Chapter 1:DaqLink OverviewThis chapter provides a general overview of the DaqLinksystem.1.1. DaqLink IntroductionLight, Portable and Independent LoggingWith built-in temperature and humidity sensors, plus fourexternal probe inputs the DaqLink standalone data loggerensures a low cost, reliable and accurate solution. TheDaqLink logger is a 16-bit, mobile data acquisition device forcontinuous indoor or outdoor data monitoring.The DaqLink system is comprised of two data logger models,measuring a broad range of parameters on four externalinputs for direct measurement and recording of PT-100,thermocouple, 0 to 1 V, 4 to 20 mA, contact, frequency andpulse sensors, as well as internal temperature and relativehumidity sensors.With its high resolution and fast Analog to Digital converter(ADC), DaqLink data loggers meet the majority of dataacquisition requirements in most industrial applications. EveryDaqLink logger unit is embedded with a unique serial numberand can be loaded with a descriptive comment for safeidentification. An internal clock and calendar keeps track of thetime and date of every sample measured.DaqLink loggers can automatically activate external alarmevents when data is outside a specified range. Email and SMSnotifications can be sent to predefined contacts.1

The DaqLink system is powered by the powerful DaqLinksoftware. The Windows based software is the centralmanagement interface of the DaqLink network. Whenconnected via USB cable to the PC, DaqLink data can bemonitored online and displayed in real-time graphs or tables.Analyze data with various mathematical tools, or export datato a spreadsheet.The software also enables you to configure, calibrate orupdate the firmware of DaqLink units via direct USBconnection.Key DaqLink benefits include:• Real-time logging - Online operation with data results onscreen• Independence - Manual or PC operation with on-sitemonitoring via two-row LCD display• Intuitively - Simple keypad and easy-to-navigate menus• Long life - Low-power consumption and rechargeablebattery lasting up to six months• Flexibility - Four alarm levels with visual LCD, and audiblealarms• Non-stop logging - Continuous data storage to largeonboard memory and periodic USB downloads1.2. The DaqLink SystemThe basic DaqLink system will contain at least one of thefollowing units:• DaqLink data logger – Part Number DBSA710 orDBSA720• Mini-USB communication cable• Power adapter (one per DaqLink unit ordered)2

• DaqLink software CD containing user guide1.2.1. The Data LoggerThere are two data logger models compatible with theDaqLink system. These loggers support up to four externalsensors and two internal sensors, temperature and humidity,depending on the specific model. Data is recorded and storedto the logger’s internal memory and transmitted over thenetwork to the DaqLink software running on the PC.The data logger is programmed to consume as little power aspossible during operation, in order to conserve the battery life.When not transmitting or recording data the units are in sleepmode and they wake up when needed.The battery for the DBSA710 and DBSA720 is rechargeableand can run up to several months on one charge, dependingon the logger configuration.Refer to section 3.5.3 for more information.Note: Battery life depends on the logger sampling rate,transmission rate, type of sensor, and number of measuredsensors.3

Hardware AccessoriesThe DaqLink system includes the following accessories:• Mini-USB cable for connecting data logger to PC• Power adapter to power the data logger4

1.2.3. DaqLink SoftwareThe user interface for the DaqLink system, the DaqLinksoftware CD is provided together with the DaqLink hardwareand includes the following features:• Data display, management, storage and data diagnostics• Alarm settings: Email and SMS notifications, visual andaudible alarms• Sensor definition• Sensor calibration• Firmware update• Automatic software update (via Fourier server)The software interface is described in detail in Chapter 4.5

Chapter 2:DaqLinkImplementation GuideFourier Systems suggests first time users of the DaqLinksystem read this chapter before drilling down into the manyfeatures of the system described later in the user guide. TheImplementation Guide will give you a clear understanding ofthe basic aspects of setting up the system, and getting thedata logger up and running.2.1. Pre-setup RequirementsPrior to commencing with the DaqLink implementation youmust have the following requirements in place:PC• 24/7 availability, if online data monitoring is required• Reliable AC power• Sufficient hard disk space to store loggers’ data• One free USB portDaqLink devicesAt least one DaqLink logger DBSA710 or DBSA720Mini-USB cableThe mini-USB cable connects the data logger to the PC forlogger configuration and data download (and is supplied withthe PC Suite software kit).6

2.2. Launching the Software1. Install the DaqLink software on the PC workstation. Referto section 4.1: Installing DaqLink Software on page 38 formore details.2. Once the software and associated components havebeen installed, launch DaqLink from your DaqLinkdesktop shortcut .3. The main DaqLink window is launched. The default viewis called Map View.Figure 1: Main DaqLink window7

4. Check for DaqLink updates. Go to Help > Check forUpdates from the DaqLink main menu to check for newerversions of DaqLink software and firmware released sinceyou purchased your system. For more details on theUpdate feature go to Chapter 5: Updating DaqLinkSoftware and Firmware.2.3. Connecting the LoggerNote: Only one DaqLink logger will be detected by the PC ata time.1. Only once the DaqLink software and USB driver havebeen installed, connect the DaqLink data logger(DBSA710 or DBSA720) to the Fourier-supplied poweradapter.Note: Only use adapters provided by Fourier Systems. Use ofthe wrong adapter could damage your DaqLink units.2. Turn on the unit by pressing the Scroll button onthe front keypad. The unit will beep when turned on.3. Connect the mini-USB cable to the computer and to thedata logger’s mini-USB port.4. From the DaqLink main menu, go to Logger > DetectLogger. The data logger icon will appear in the Map Viewindicating that the logger is detected.8

Figure 2: Adding data logger icon to Map ViewNote: If the logger is not recognized by the software tryconnecting the mini-USB cable to another USB port on thePC. Or select Logger > Detect Logger again in the mainmenu.Should you disconnect the logger’s USB cable or poweradapter (and the battery eventually dies), the logger iconwill be grayed out:Note: You can move the logger icon elsewhere on the screenby going to Tools > Lock Map View and unselecting thisoption.2.4. Charging DaqLink LoggersThis section refers to charging the DBSA710 or DBSA720loggers.Note: Only use adapters provided by Fourier Systems. Use ofthe wrong adapter could damage your DaqLink units.If the loggers will run from the battery supply make sure to firstcharge each of the loggers for 16 hours before use in ordermaximize the battery life. A fully charged battery can lastseveral months, depending on your logger configuration.9

If the loggers will run from the AC power supply, when firstconnected to the AC adapter the logger will always initiate the16 hour charge cycle.Note: For loggers measuring data with the internaltemperature sensor, it is critical to note that during the chargecycle the logger will heat up thereby causing the internaltemperature sensor reading to rise up to 10 ˚C above ambienttemperature. Once the charging process is complete, thelogger will cool down and the internal temperature sensorreadings will return to normal.For loggers remaining connected to AC power, to prevent thelogger from heating up again following the initial charge cycle,the logger will receive a one minute trickle charge each dayrather than stay continually charged. This is sufficient toensure the logger doesn’t self-discharge and will maintain thelogger’s full charge status.Refer to section 3.5.1 for more details on the DaqLink loggers’power supply.2.5. Loading Map ViewBackgroundLoad an image into the DaqLink software showing a map ofyour facility in order to place the Logger icons in their relativepositions. As you deploy more standalone loggers, this willprove very helpful.• Double click the Map View background to browse to theimage directory and load the image.

You may onlyconfigure In-4, or configure In-1 and In-3, for example, whensetting up the logger via the software.21

3.3.4. External PT-100 SensorConnectionThe PT-100 sensor, as supplied by Fourier Systems, comespre-wired to the data logger’s terminal block.The PT-100 positive polarity (red) and ground (white) wiresare connected to the + input of the terminal block. Thenegative polarity (black) wire is connected to the – input onthe terminal block.3.3.5. Programming Limitations forDBSA710 and DBSA720The standard sampling rate for all sensors on all inputs is froma maximum of one sample every second to a minimum of onesample every 18 hours. However, there are certain limitationsusing a specific combination of sensors, which must be takeninto account when programming the DaqLink data loggers.Note: The software integrates all programming limitationsautomatically when configuring the loggers.Please refer to the table below for DaqLink programminglimitations, where:PT100, Thermocouple J, K or T = AInternal Digital Temperature (on DBSA720) = BSensorCombination3 x A4 x AA + BMaximumSampling RateOne sample everythree secondsExample SetupIn-1: PT-100In-2: TC-JIn-3: TC-J22

External Alarm OutputThe DaqLink system supports connection of an external alarme.g. siren, audible alarm, to In-1 of the DBSA710 andDBSA720 data loggers.When connected to the logger, the external alarm will beactivated only when that logger is in alarm status.Once there is no alarm status, the external alarm will bedeactivated.Data Logger External AlarmIn-1 of the DBSA710 and DBSA720 serves either as astandard sensor input or as an external alarm output. Ensurethe logger is connected to AC power if connected to anexternal alarm.Configure In-1 as Alarm Normally Open or Alarm NormallyClosed in the logger Setup window in the DaqLink software.23

Normally Open will result in the alarm being activated duringalarm status (the circuit will be closed).Normally Closed will result in the alarm being activated whenlogger is not in alarm and therefore deactivated when there isan alarm (the circuit will be opened).Connect In-1 to your external alarm device and connect thelogger to AC power.Use the Alarm Setup tab in the Setup dialog to define thelogger alarm settings. If these settings are breached then thealarm will be activated.External Alarm SchematicSee the schematic below explaining how to hook up anexternal alarm to the DaqLink unit.- +- +Relay- +Alarm device(e.g. siren)+-3-4 V batteryto power relayFigure 12: External alarm schematic24

PolarityCurrent, voltage, thermocouples and user defined sensorshave distinct polarity. Be careful to connect them in the rightpolarity.3.3.8. Frequency/Pulse CounterConnect the signal wires to In-4 terminal blocks, and selectFrequency or Pulse counter for Input 4 from the loggerSetup window in the DaqLink software. Inputs 1 to 3 are stillavailable for other sensors.The Frequency/Pulse counter is optically isolated from theinternal circuitry and can simultaneously measure a signalsource, together with another input.3.3.9. User Defined SensorsDaqLink provides a simple and straightforward tool fordefining a limited number of custom sensors. Almost anysensor or transducer with 0 – 1 V or 4 – 20 mA output is25

accepted by the DaqLink logger and its electrical units areautomatically scaled to meaningful user-defined engineeringunits.The sensor definitions are stored in the logger’s memory andare added to the sensors list. The sensor’s readings aredisplayed in the user defined units only in the DaqLinksoftware. Future versions will also support displaying the userdefined engineering units on the logger LCD.Refer to section 4.5.1 for more details.3.3.10. Sensor AlarmsVia the software, users can define minimum and maximumalarm levels for each input individually. Users can define prelowand pre-high alarm levels, for an additional level of safetyin case the logger is approaching an actual breach of alarm.The DaqLink logger display indicates when the sensor readingis in alarm of any type. The symbols AL-H, AL-L, AL-P-H orAL-P-L are visible next to the corresponding input readings.Refer to section 4.12 for more details.3.3.11. Sensor CalibrationThe DaqLink data logger is shipped fully calibrated. However,further calibration can be applied via the DaqLink software.The calibration parameters are sent to the data loggers viaUSB connection and stored in the logger’s memory.Users may calibrate individual inputs as well as all inputs atonce. Calibration settings may be saved and then loaded intothe logger at a later date if the calibration settings havechanged.Refer to section 4.12.4 for more details.26

3.4. Unit Serial Number andCommentEvery DaqLink data logger unit is embedded with a uniqueserial number.The data logger only can be loaded with a descriptivecomment to identify its task and location. You may add or editthe logger comment via the DaqLink software.Every time data is transferred to the computer it is labeledboth with the logger’s serial number and comment and isdisplayed in the graph or data table view.The unit serial number is also marked on a sticker on the backof the product.3.5. Power Supply3.5.1. DBSA710 and DBSA720 DataLoggersThe DBSA710 and DBSA720 data loggers run from aninternal NiMh rechargeable battery as well as from externalAC power supply. Depending on the logger configuration,from a fully charged battery, the data logger can run for up toseveral months. Refer to section 3.5.3 for more details onbattery life.Note: Charge the data logger units for 16 hours before usingthem for the first time.When connected to external power supply, the data loggerbattery will not be charged when the unit is turned off. This willallow the system to protect the battery from overheating.27

First Time ChargingFrom a fully drained battery, you must charge the battery for16 hours to bring it to a full charge. Once the charge cycle iscomplete, the logger will run from the external power supply,without draining (or charging) the internal battery. In order tomaintain a fully charged battery and ensure the batterydoesn’t self-discharge, the battery charger will daily chargethe unit for one minute to maintain the battery capacity.Note: Before storing the DaqLink units make sure you haveunplugged all the sensors and turned the units off via thekeypad.Standard ChargingWhenever a logger is reconnected to the charger it will beginthe 16-hour charge cycle, no matter what the status of thebattery. Once the charging cycle is complete the logger willrun from external power supply.Effect of Charging Battery on TemperatureSensorFor loggers measuring data with the internal temperaturesensor, it is critical to note that during the charge cycle thelogger will heat up thereby causing the internal temperaturesensor reading to rise by up to 10 ˚C above ambienttemperature. Once the charging process is complete, thelogger will cool down and the internal temperature sensorreadings will return to normal.For loggers remaining connected to AC power, to prevent thelogger from heating up again following the initial charge cycle,the logger will receive a one minute trickle charge each dayrather than stay continually charged. This is sufficient toensure the logger doesn’t self-discharge and will maintain thelogger’s full charge status.28

3.5.2. Power AdapterThe DaqLink power adapter is used to power the DBSA710and DBSA720 units. The mains adaptor (AC/DC adaptor)converts mains power (from a wall outlet) to a voltage suitableto the DaqLink hardware unit.• Output: Capacitor filtered 9 to 12 VDC, 300 mA• Female plug, center negativeNote: Only use Fourier-supplied power adapters to avoiddamaging the units with incorrect power supply.3.5.3. Data Logger Battery LifeBattery life depends on the logger sampling rate, type ofsensor, and number of measured sensors.DBSA710 and DBSA720 can last up to six months on acharged battery depending on logger configuration.3.6. USB Communication CableA mini USB communication cable is supplied as part of theDaqLink PC Suite. This cable connects the DaqLink datalogger to the DaqLink PC workstation. When connected to thePC the logger can communicate with the software forconfiguration and data download purposes, for example.The USB cable also powers the logger when connected to thePC but it does not charge the internal battery.29

Note: The USB driver is installed as part of the softwareinstallation process. Without this driver the PC won’t detectthe logger.

The sampling ratewill vary depending on the number and type of sensors yousetup. Refer to section 3.3.5 on page 22.Memory StateFrom the drop-down menu you have the following options:• Online Mode: For working with logger connected to PC.Data will be transmitted in real-time i.e. at the same timeas the sampling rate.• Optimized Memory Mode: For working with the loggeras a standalone device, not connected to the PC. In thismode, the memory is more efficiently managed as thedata does not need to be transmitted together with thesampling rate. Use the Transmissions intervalparameter in the Setup window to see the rate at whichthe data will be displayed on the logger or in the software.Note: If used when connected to the PC, the data will notbe transmitted in real-time.Cyclic ModeIf this checkbox is not selected, the logger will stop recordingdata when the memory capacity is filled.Enabling Cyclic mode will result in the oldest samples in thememory being overwritten by new samples once the memoryis full. This allows continuous data logging.73

Averaging PointsYou can choose have online averaging of up to 10 pointsaround the real value in order to smooth the data readings, ifthey are a little noisy. The recommended averaging is 4samples.Note: If configuring Alarm duration with averaging pointsselected, the alarm will be counted from the time of the lastsampling point used to calculate the average.Temperature UnitsToggle between °C and °F. This applies to the readingsdisplayed on the logger LCD as well as in the software.Anti Tamper ModeTo prevent tampering with the DaqLink logger, selecting thisoption will disable the following features on the logger menu:• Pause• Reset• Stop and turn off unitActive SensorsDepending on the logger model, you can activate up to twointernal sensors and four external sensors. Simply select theinputs you want to use and then select the sensor types fromthe adjacent drop-down menu. You don’t have to select theexternal sensor input in any order. You may select only Input4 if you desire.Note: On the DBSA720 you cannot run the humidity sensorwithout running the temperature sensor in parallel.74

This is because when using the DBSA720 data logger andselecting the internal humidity sensor in the Device Setupdialog, the internal digital temperature sensor willautomatically be selected as well. This sensor provides thetemperature compensation necessary for the humidity sensorto reach the 3% accuracy as stated in the sensorspecifications. It is not used for recording temperature. Theinternal digital sensor is used to record temperature on theDBSA720.Custom Sensor NamesYou can also give the sensor a custom name, which willappear in the software when viewing the data. This isconvenient when using several of the same type of sensorsand you wish to differentiate between them in terms of theirenvironment or material it is measuring.Recording TimeThis field displays the length of time the logger memory will beable to record for depending upon the number of sensorsused and sampling rate.Setup and RunClicking Setup and Run will send the setup to the logger andimmediately start logging data.Setup OnlyClicking Setup Only will send the setup to the logger but it willnot actually start logging data. You will need to select Runfrom the Logger context menu or go back into the Setupdialog.75

CloseClicking Close will close the Setup dialog without saving anyof your configurations.Note: Running the logger clears the logger memory. Allpreviously recorded data will be erased when you begin a newlogging session.4.11.2. Alarm Setup TabA major feature of the DaqLink system is the ability toconfigure alarm levels into the loggers so any breach of theselevels as recorded on the data logger is monitored by thesoftware, and the user is notified via Email/SMS/audible andvisual indicators.The Alarm Setup tab lets you configure each sensor for thefollowing alarms:• Low• Pre-Low• Pre-High• High• Contact Open / Contact Close (when the Contact sensoris selected)Using the Pre Alarms gives the user ample warning of apossible breach of real alarm levels, so necessary measurescan be taken to prevent such a breach.Simply select the check box for the type of alarm you wish tobe notified. You can select all alarms too. Enter the alarmvalue in the text box.76

Figure 30: Alarm Setup tabAlarm Delay and Pre-alarm DelayThe time until the alarm (or pre-alarm) is activated. You maynot want to have the alarm sound immediately after the alarmlevel is breached as you are only interested in a conditionwhere the alarm level lasted a certain amount of time.For example, if monitoring change of temperature in a freezer,you would only be interested in a High alarm which lastedmore than one minute as anything else could just be causedby the freezer door opening for a few seconds, as opposed toa power failure leading to rise in temperature.77

Alarm DurationThe duration of the alarm that is set off by one or moresensors breaching the alarm level.Note: Ensure Averaging is set to zero when enabling theAlarm Duration feature.Sound Alarm during Pre-alarmYou also have the option to sound the alarm in the softwareduring a pre-alarm scenario, not just for a standard alarm.Once you have configured your alarms, you may return to theDevice Setup tab or click one of the Setup buttons at thebottom of the tab.4.12. Alarm Notifications SetupOnce you have completed the logger alarm setup in section4.11.2 above, you can now configure DaqLink to send alarmnotifications via Email or SMS.From the Tools menu select one of the following options,depending on the type of notifications required:• Email Alarm Notification• SMS Alarm NotificationOr click the Email or SMS icons located in the uppertoolbar in order to launch the notification dialog.Note: To enable sending of Email or SMS first define theEmail and SMS settings in the Tools > Options dialog.Connect a GSM modem to the PC if sending SMS’s. Refer tosection 4.6 on page 58 for more details.78

The Alarm Notifications dialog also lets you manage yourcontact list of alarm notification recipients.Figure 31: Alarm Notifications Setup dialogAs the Email and SMS Alarm Notifications must be definedseparately, they each have separate dialogs. However theinterface is identical and the contacts are stored in the samedatabase.The Email/SMS Notifications dialog is divided into thefollowing tabs:• Notifications Setup• Contacts tab• Groups tab79

4.12.1. Contacts TabThe first step is to create the contacts who shall be receivingthe notifications. The ability to manage contacts is possiblefrom both the Email and SMS Notifications dialogs.1. Click the Contacts tab and then click Add Contact.Figure 32: Adding a contact2. In this dialog you must first enter the contact name in theName field. That is the only mandatory field but if youdon’t enter at least the phone number or Email then theywon’t receive any alarm notifications.The other fields in the dialog are as follows:• Title: Corporate position• Phone number: The number the DaqLink softwarewill use to send the SMS notification.80

Note: The phone number field supports the followingcharacters: 0-9, # , *, -, ( ), +• Email: The address the DaqLink software will use tosend the Email notification.• Workday Start and End: You can define the hours inwhich the contact will be eligible to receive thenotifications i.e. so they don’t receive SMS or Emailwhile in the office, or vice versa.• Vacation: You can define when the contact is onvacation so they won’t receive any notifications overthis period.• Number of SMS resends: The number of timesDaqLink will send follow-up SMS’s with the alarmnotification. The maximum is nine resends per alarm.The gap between each resend is five minutes.Note: In order to stop receiving SMS resends, you cansimply send an SMS with ‘OK’ in the message body tothe GSM SIM card’s phone number.3. When the contact details have been entered, click OK.4. The contact will be added to the Contacts tab. You maychoose to add another contact, edit an existing contact orremove a contact from the list.4.12.2. Groups Tab1. Click the Groups tab and then click Add Group. TheGroup Details dialog will open.81

Figure 33: Adding a group2. Enter a Group name and add your existing contacts to thegroup by selecting the checkbox next to the Contactname.3. Click OK to create the Group. In the Groups tab you maychoose to add a group, edit an existing group or remove agroup from the list.4.12.3. Notifications Setup Tab1. Once the contacts have been created you may startdefining which contacts should receive the alarmnotifications.2. The pane on the left-hand side of the Notifications Setuptab displays all loggers, which have been configured inyour facility. You must define the alarm notifications foreach unit in turn. Select the first unit you wish to define.3. The Email or SMS tab is now active for the unit selectedin step 1 above. In this tab, select the type of alarm for82

which the notification should be sent in the event that thepredefined alarm level is breached.4. Only the sensors which were configured in the loggerSetup, with alarms levels, are enabled in this tab.5. Select the checkboxes according to the type of sensoralarm for which notifications should be sent.You may also select a Normalized alarm. A notificationwill be sent when the logger returns to normal levelshaving previously been in alarm state.6. Click the Contact button adjacent to each of the sensorswhich have defined alarms. In the Select Contact dialog,select the contact and/or group that will receive thenotification.7. You can also click Check All to select all the sensoralarms for notification.Note: In Optimized Memory Mode, when the loggertransmission rate is slower than the sampling rate, analarm notification is still sent even if the loggertransmission time hasn’t passed. For example, if thesampling rate is every 5 minutes, and the transmissionrate is every 10 minutes, if a logger reaches a high alarmafter 7 minutes a notification will be sent. The systemwon’t wait until the scheduled transmission time.83

4.12.4. Email and SMS NotificationFormatsEmail Notification FormatWhen the Email notification is sent the recipient receives theEmail in the following format:Email Header:DaqLink Alarm Internal Temperature (Last recorded 25.47C)Low AlarmEmail Body:DaqLink AlarmComment: Factory 1/FS/N: 80893208-07-09 13:53:41Internal Temperature Low AlarmLast recorded 25.47 CThe Email header contains the sensor type, last recordedsample, and alarm type.In addition the Email body contains the logger comment, serialnumber, time stamp of last sample and value of last sample.SMS Notification FormatWhen the SMS notification is sent the recipient receives theSMS in the following format. (The logger comment isdisplayed in the first row).Factory 1/FSensor: Internal Digital Temperature – HighAlarm last recorded 29.59 C84

4.13. CalibrationThe DaqLink data loggers are shipped fully calibrated with acalibration certificate. However, DaqLink does provide asimple and efficient process for users wishing to calibrate theDaqLink data loggers themselves. The process itself can beperformed when the logger is connected to the PC via USB. Acalibrator or other type of calibration instrument is necessary.The Calibration options are accessible via the Logger contextmenu in the Map View (right-clicking the Logger icon).Before performing logger calibration, the logger must be inStop mode. In addition, all of the calibration options areaccessible with a password making it difficult for nonauthorizedusers of the system to tamper with the loggers’calibration settings.Note: The default password is 1234. The password can bechanged in the password dialog box.The Calibration option menu options are:• Calibration: Opens the main Calibration dialog• Save Calibration: Saves the logger’s current calibrationsettings• Load Calibration: Loads a logger’s previously savedcalibration settings.• Reset Calibration: Resets the logger’s calibrationsettings so that the raw hardware data is obtained,without any software calibration applied to these values.• Restore Factory Calibration Default: Restores thelogger’s calibration settings to the factory calibration i.e.85

the calibration settings it received prior to shipment fromFourier.4.13.1. Introduction to DaqLinkCalibrationAlthough the DaqLink data loggers come fully calibrated, thesoftware enables you to calibrate any of the DaqLink sensors,on any input. The calibration parameters are sent to the datalogger and stored in its memory.DaqLink employs two different calibration methods: Twopointcalibration and Offset calibration.Each sensor can be calibrated using the Two-point calibrationmethod, and then tweaked using offset calibration, except forthe Thermocouples. These sensors require offset calibrationonly.Sensor Type CalibrationMethodTwo-pointCurrent4 – 20 mAcalibrationTwo-pointHumidity (Internal) DigitalcalibrationTemperature(Internal)Temperature(Internal)TemperatureDigitalPT-100PT-100 2-wireTwo-pointcalibrationTwo-pointcalibration andoffsetTwo-pointcalibration andoffsetTemperature Thermocouple J Offset calibration86

Temperature Thermocouple K Offset calibrationTemperature Thermocouple T Offset calibrationVoltageVoltage0 to 1 V0 to 50 mVTwo-pointcalibrationTwo-pointcalibrationCalibration TipsPrior to any two-point calibration it is recommended to restorefactory calibration defaults.Prior to calibrating any of the thermocouple sensor types,calibrate the Voltage 50 mV sensor as this will set the gain(slope) of all thermocouple sensor types.After calibrating 50 mV, TC-J, TC-K or TC-T sensor types forall inputs you can refine the offset calibration for each inputindividually.You may calibrate all thermocouple sensor types at once, orindividually.Prior to calibrating the PT-100 input, you must first performReset Calibration in the Calibration dialog.Two-point CalibrationThe two-point calibration sets the gain (slope) and offset(intercept) of the sensor's conversion function.Use the two-point calibration to calibrate all DaqLink sensorsexcept for the Thermocouples. In some cases you may needto refine your calibration using the fine offset tuning tool.87

Offset CalibrationTo calibrate the Thermocouple temperature sensors: TC-J,TC-K and TC-T, first calibrate the 50 mV sensor type. That willset the slope for all Thermocouple temperature sensors. Thenproceed to adjust the offset using the Offset calibrationtechnique.4.13.2. Calibrating the Data LoggerFigure 34: Calibration dialog1. From the Map View, open the Logger context menu andselect Stop.2. Select Calibration > Calibrate and enter the password inthe Password dialog.88

3. Select the sensor you wish to calibrate from the Sensordrop-down menu.4. If calibrating an external sensor, select the inputs tocalibrate. Select All or an individual input, 1 to 4.5. Click Setup to send the sensor setup to the logger.Note: The calibration process does not delete the logger’ssetup prior to calibration. Once Calibration is complete theoriginal logger setup will be restored.6. If you selected All inputs, then by default the logger willbe setup to log data on Input 1 during the calibrationprocess. Otherwise, if you selected a specific input, it willsetup the logger to calibrate on that input.Logger Data PaneThe Logger Data pane displays real-time readings on thelogger, at a default sampling rate of one per second. You canalso view the logger’s general status. Use the Logger Datapane to verify your logger is properly calibrated.The Calibration dialog will enable either Two-point or Offsetcalibration, or both, depending on the sensor selected.Note: The calibrated sensor parameters will be saved both inthe DaqLink logger and in the software memory, so there is noneed to calibrate the logger every time you run the software.4.13.3. Performing a Two-pointCalibrationTo perform a two-point calibration, you must have tworeference points to input against the real logger sensorvalues.89

Figure 35: Two-point calibration window1. In the Point #1 field, enter the first Reference Value andthe corresponding Logger Value.2. In the Point #2 field, enter the second Reference Valueand the corresponding Logger Value.Note: If you are using a calibrator and the logger is currentlydisplaying the real value to be calibrated, press the Copybutton to copy the real value to the Logger Value text box.3. Press Send Calibration to send these values to thelogger memory.4. Compare the real value in the Logger Data pane to thereference value. If the values are within an acceptablemargin of error you may close the Calibration window, ormove on to the next sensor or input.5. If the values are still not accurate enough, you canperform Offset calibration to tweak with values further.Note: Fourier strongly recommends calibrating using thedefault Reference values that appear in the two Referencevalue text boxes for each sensor.90

4.13.4. Performing an OffsetCalibrationIf, after the Two-point calibration procedure, the logger stillexhibits some offset value use the Offset calibration tool tocorrect it.The offset value is the difference between the value displayedby the DaqLink logger and the reference value. For example ifthe calibrator is set to 0 °C and the logger reads 1 °C theoffset value is +1, but if the logger reads −1 °C then the offsetvalue is −1.To perform an Offset calibration, simply select the Offsetcalibration radio button to enable the Offset text box. ForThermocouples you will only have the option to perform anOffset calibration.Enter the offset value in the text box and click SendCalibration. Continue to adjust the offset accordingly untilsatisfied with the readings.4.13.5. Setting the Offset to a SpecificInputAfter setting the offset to all inputs simultaneously, you canset the offset of each input separately for even betteraccuracy.To set the offset of a specific input:1. Measure two known reference values making sure to usethe input you need to calibrate.2. Enter the offset value as described in section 4.13.4above, making sure to select the correct input numberinstead of All.91

3. You can repeat the procedure for every input.4.13.6. Calibrating the InternalTemperature Sensor on theDBSA710The DBSA710’s internal temperature sensor is a PT-100sensor. Calibration of this sensor is performed by calibratingthe external PT-100 input i.e. two-point calibration followed byoffset calibration.1. In the Calibration dialog, select PT-100 in the Sensordrop-down menu and select All inputs.2. Press Setup to proceed.3. Connect a calibrator or an actual PT-100 sensor to Input-1. Calibrate the input using the reference values.Once this calibration procedure is complete both the logger’sinternal temperature sensor (PT-100) and external PT-100inputs will be calibrated.4.13.7. Calibrating the External PT-100Sensor InputPT-100 calibration is a standard 2-point calibration followed byoffset calibration. Once the PT-100 sensor has been selectedin the Sensor drop-down menu, click the Reset Calibrationbutton. Then proceed with the 2-point calibration procedure.Before each calibration this step must be performed otherwisethe calibration will not be accurate.92

4.13.8. Saving Calibration SettingsAt any time you may manually save the logger’s calibrationsettings locally to your PC.1. Open the logger context menu, select Calibration > SaveCalibration and enter the password to access thisfeature.2. The Save As dialog will open. Name the calibration file(with extension .dcf) and save it either in the defaultCalibration folder in the DaqLink directory or in a folder ofyour choice.4.13.9. Loading Calibration SettingsYou can load a previously saved DaqLink .dcf calibration fileat any time to restore a logger’s specific calibration settings.1. Open the logger context menu, select Calibration > LoadCalibration and enter the password to access thisfeature.2. In the Open dialog, browse to the calibration file you needand click Open. The logger will be updated with the newcalibration settings.4.14.
