Allow at least 30 minutesfor warm-up.• Do not wire to unused controller terminals.• Make sure to wire properly with correct polarity ofterminals.Publication 900-UM003C-EN-E - January 2004

Preparations 2-9• Separate input leads and power lines in order to protect theBulletin 900-TC32 and its low voltage sensor and communication linesfrom external noise.• Use AWG 24…14 leads for terminals 1…6 and AWG 28…22 leads forterminals 7…9.• Tighten the terminal screws using a torque no greater than 0.24 Nm(2.12 lb-in.) for terminals 1…6 and a torque no greater than 0.13 Nm(1.15 lb-in.) for terminals 7…9. Loose screws may cause a malfunctionif the wires come out of the terminal.WiringPower SupplyThe controller requires an external power source for operation. Connect toterminals 1 and 2. The following table shows the specifications.Table 2.AInput Power Supply100…240V AC, 50/60 Hz24V AC, 50/60 Hz24V (not polarity sensitive)Bulletin 900-TC324.3 VA @ 120V, 7 VA @ 240V4.0 VA2.5 WATTENTION!Use a power supply matched to the power specifications ofthe Bulletin 900-TC32. Also, make sure that rated voltage isattained within 2 seconds of turning the power ON.Standard insulation is applied to the power supply I/O sections. If rein forcedinsulation is required, connect the input and output terminals to a devicewithout any exposed current-carrying parts or to a device with standardinsulation suitable for the maximum operating voltage of the power supplyI/O section.When mounting a noise filter on the power supply, make sure to first check thefilter’s voltage and current capacity, and then mount the filter as close aspossible to the Bulletin 900-TC32.Publication 900-UM003C-EN-E - January 2004

2-10 PreparationsWiring Input/Sensor DevicesConnect sensors to terminals 7…9 as follows according to the input type.Figure 2.87 8 9– +Thermocouple7 8 9A B BPlatinum resistancethermometer7 8 9– +VAnalog inputInput/Sensor Wiring Considerations• When the thermocouple leads are extended, make sure to usethermocouple extension wire matched to the type of thermocouple.• For a thermocouple, make sure to follow the polarity color codeconvention.• If there is a large error in the measurement values, make sure that inputcompensation has been properly configured.• RTDs can be either 2- or 3-wire types. If a 3-wire type is used, thecontroller provides lead wire resistance compensation up to 5 Ωresistance. If using 24 AWG lead wire, this is approximately 59 m ofwire. Use larger gauge wire if longer length is required.• For RTDs, the controller source is approximately 1 mA of current.• If a cooling fan is used in the panel enclosure, prevent only the terminalblock from being cooled when using thermocouples. Otherwise, thismay result in a measurement error.• To reduce induced electrical noise, the leads on the temperaturecontroller’s terminal block must be wired separately fromlarge-voltage/large-current power leads. Also, avoid wiring leads inparallel with power leads or in the same wiring path. Other methodssuch as separating conduits and wiring ducts, or using shield wire arealso effective.• When the platinum resistance detector leads are extended, use the leadhaving the smallest resistance to equalize the resistance of the threeleads.Publication 900-UM003C-EN-E - January 2004

The following diagram shows theavailable hard contact or fixed voltage (SSR) outputs and their internalequalizing circuits.Figure 2.9+VGND3 4 3 4LRelay output+ –LVoltage output (SSR)The following table shows the specifications for each output type.Table 2.BOutput TypeRelayVoltage (PNP type)SpecificationsSPST-NO, 250V AC @ 2 A, 30V DC @ 2 A (max. resistive load);electrical life: 100,000 operations, min. load 1V @ 1 mA12V DC, 21 mA (with current limit protection)Output Wiring Considerations• The PNP voltage output (control output) is not electrically isolated fromthe internal circuits. When using a grounding thermocouple, do notconnect the control output terminals to the ground. If the controloutput terminals are connected to the ground, errors will occur in themeasured temperature values as a result of leakage current.• The life expectancy of the output relays varies greatly with the switchingcapacity and other switching conditions. Always use the output relayswithin their rated load and electrical life expectancy. If an output relay isused beyond its life expectancy, its contacts may become fused orburned.• Use the Bulletin 900-TC32 Temperature Controller outputs within therated load. Not doing so may cause damage or fire.• About 4 seconds are required for outputs to turn ON when thecontroller power is turned ON. Take this into consideration when thetemperature controller is incorporated into a sequence circuit.Publication 900-UM003C-EN-E - January 2004

3-10 Configuration and Basic OperationConfiguring the Input TypeThe Bulletin 900-TC32 supports four input/sensor types: platinum resistancethermometer, thermocouple, non-contact temperature sensor, and 0…50 mVanalog inputs. Configure the input type matched to the sensor used in theInput Type parameter (see Table A.B, List of Input Types). TheBulletin 900-TC32 general controller specifications support two types ofinputs, platinum resistance thermometer and thermocouple temperaturesensors, whose Set Values differ. Check the type of Bulletin 900-TC32 atpurchase (see Table 1.A).Input TypeExample Operation Procedure — Configuring the Input Type ThermocoupleK-20.0…500.0°C1. Press the key for at least 3 seconds to move from the Operationfunction group to the Initial Setting function group.Figure 3.7Operation function groupInitial setting function groupInput type2. Press the U key to configure the Set Value for the desired sensor.Entering the Set Value will configure the controller for the applicableinput type and range. Example: When you use K thermocouple(–20.0…+500.0°C), enter 1 as the Set Value.Figure 3.8Note: The selected Set Value is loaded into controller memory if you donot operate the keys on the front panel for 2 seconds after changing theparameter, or by pressing the or M keys. This applies to changing allvalues and/or parameters.Selecting °C/°FTemperature UnitThe Bulletin 900-TC32 allows you to select either °C or °F as the temperatureunit.Configure the temperature unit in the Temperature Unit parameter of InitialSetting function group. Note: The default is °C.Publication 900-UM003C-EN-E - January 2004

The upper display (No. 1 display) shows the process value (PV),and the lower display (No. 2 display) displays the set point (SV or SP).Changing the SPThe set point cannot be changed when the Operation/Adjustment Protectionparameter is set to 3. For details, see p. 4-23, Using the Key Protect Function Group.To change the set point, press the U or D key in the PV/SP parameter(Operation function group), and load the desired value. The new set point isloaded into memory 2 seconds after you have specified the new value.Publication 900-UM003C-EN-E - January 2004

The set point is 0°C.Figure 3.13Operation function group2. Press the U or D key until the set point changes to 200°C. To load thevalue into controller memory, either press the key or wait 2 seconds.Figure 3.14Selecting PID Control orON/OFF ControlOverviewThe Bulletin 900-TC32 supports two control methods, 2-PID control andON/OFF control. The control method is selected by the PID/ON/OFFparameter in the Initial Setting function group. When this parameter is set topid, 2-PID control is set, and when set to onof, ON/OFF control is set.Note: The default is ON/OFF control.2-PID ControlPID control parameters are set by AT (auto-tuning), ST (self-tuning), ormanual setup. For PID control, set the PID constants in the ProportionalBand (P), Integral Time (I), and Derivative Time (D) parameters. For moredetails, see p. 3-18, Determining PID Constants (AT, ST, Manual Setup).ON/OFF ControlIn the ON/OFF control method, the control output (MV) is turned ON whenthe process value is lower than the current set point, and the control output isturned OFF when the process value is higher than the current set point. Thisis known as reverse operation. Direct operation refers to control where themanipulated variable is increased according to the increase in the processvalue.Publication 900-UM003C-EN-E - January 2004

Configuration and Basic Operation 3-13Configuring the OutputParametersControl PeriodThe Control Period parameter is used in the PID control method and allowsyou to adjust the minimum amount of time between ON cycles of theON/OFF output (MV).Figure 3.15Controlperiod(OUT1)• A shorter period may provide better ON/OFF control performance.However, for electromechanical relay outputs we recommend setting thecontrol period to 20 seconds or more. In the case of anelectromechanical relay output, doing this will increase its lifeexpectancy. If necessary, readjust the control period by trial operation tomeet the needs of the application.• Set the control period in the Control Period (OUT1) parameter (InitialSetting function group). Note: The default is 20 seconds.Note: The Control Period parameter allows what is typically called “timeproportioning” ON/OFF control to be done in the 2-PID method.Direct/Reverse OperationFigure 3.16Direct operation refers to control where the manipulated variable (MV) isincreased according to the increase in the process value (PV). Alternatively,reverse operation refers to control where the manipulated variable is decreasedaccording to the increase in the process value (see Figure 3.10). Direct/reverseoperation can be used in ON/OFF or PID control.Publication 900-UM003C-EN-E - January 2004

3-16 Configuration and Basic OperationExecuting the ON/OFFControl MethodOverviewIn the reverse operation ON/OFF control method, the control output (MV)turns OFF when the controlled temperature (PV) reaches the user-defined setpoint. When the control output (MV) turns OFF, the controlled temperaturebegins to fall and the control output turns ON again. This operation isrepeated at a certain point. At this time, how much the temperature must fallbefore the control output turns ON again is determined by the Hysteresis(OUT1) parameter. Also, how much the manipulated variable must be adjustedin response to the increase or decrease in the process value is determined bythe Direct/Reverse Operation parameter.ON/OFF Control ParametersSwitching between 2-PID control and ON/OFF control is carried out by thePID/ON/OFF parameter (Initial Setting function group). When thisparameter is configured to pid, 2-PID control is selected, and whenconfigured to onof, ON/OFF control, is selected. Note: The default isonof.HysteresisIn the ON/OFF control method, the hysteresis is used to provide amargin/differential for switching the control output ON when the controlledtemperature moves away from the required set point. The Hysteresisparameter is used give stability to the output around the set point.The hysteresis value for the control output (OUT1) function is set by theHysteresis (OUT1) parameter. In standard hysteresis value for the heating orcooling control, the Hysteresis (OUT1) setting is used as the hysteresis setting(Adjustment function group) regardless of the control mode, heating control,or cooling control.Figure 3.24 Reverse OperationReverse operationONHysteresis (OUT1)OFFSet pointPVPublication 900-UM003C-EN-E - January 2004

The difference between the controlledtemperature at start of programexecution is larger than the currentproportional band (1.27+4°C) or the STstable range, whichever is larger.3. The controlled temperature at the startof program execution is smaller than theset point during reverse operation, and islarger than the set point during directoperation.4.

During reverse operation, the new setpoint is larger than the set point beforethe change; and during direct operation,the new set point is smaller than the setpoint before the change.4. The temperature is in a stable state (seeNote 2). (An equilibrium state [seeNote 3] is acceptable when the output is0% when the power is turned ON.)Note 1: The previous SRT-implemented set point is called the set pointobtained by calculating the PID constant by the previous SRT.Note 2: In this state, the measurement point is within the ST stable range.Note 3: In this state, the change width of the PV every 60 seconds is at the STstable range or less.New PID constants are not calculated by self-tuning (ST) for the currentlyconfigured set point in the following instances:• When the PID constants have been changed manually with ST set toON.• When auto-tuning (AT) has been executed.Self-Tuning (ST) Stable RangeThe self-tuning (ST) stable range is a mechanism which allows you todetermine the condition under which the ST (self-tuning) function occurs.In this example, set the ST stable range will be configured to 20°C.Example Operation Procedure1.

Chapter 4Parameter Adjustments and ApplicationConsiderationsShifting Input ValuesOverviewThe Input Shift parameter allows you to configure the controller tocompensate for possible deviation of the measured temperature (PV) to theactual temperature at the source (control target). The controller supports twotypes of input shifts: 1-point and 2-point. The input shift type is automaticallymatched to the sensor currently selected by the Input Type parameter (setvalue — see Table A.B, List of Input Types).1-Point (Uniform) ShiftOverviewFigure 4.1With 1-point shift operation, the Temperature Input Shift parameter(Adjustment function group) is applied to the entire temperature input rangein a uniform or consistent manner. In other words, the adjusted value isapplied equally to each input/sensor value read by the controller and displayedas such. For example, if the input shift value is set to 1.2°C, the process value istreated by the controller as 201.2°C after input shift is applied when themeasured process value is 200°C. (See Figure 4.2.)Figure 4.2 One-Point ShiftTemperatureUpper-limitvalueLower-limitvalue0After shiftBeforeshiftInput shift value100Input4-1 Publication 900-UM003C-EN-E - January 2004

Parameter Adjustments and Application Considerations 4-3• The input temperature range of non-contact temperature sensors can beshifted by setting an individual value for the upper and lower end pointsof the sensor range. This means that the shift can be applied equallyacross the range with separate values for each end of the range. Forexample, if the upper-limit value is set to 2°C and the lower-limit value isset to 1°C, the sensor range is shifted by an average of 1.5°C at 50%input.• Set the upper-limit value in the Upper-Limit Temperature Input ShiftValue parameter and the lower-limit value in the Lower-LimitTemperature Input Shift Value parameter.Figure 4.8 Two-Point ShiftTemperature Upper-limit temperature input shift valueUpper-limitvalueAfter shiftBefore shiftLower-limit value0Lower-limit temperatureinput shift value100InputHow to Calculate Input Shift Values (2-Point Shift)When a non-contact temperature sensor (for example, OMRON ES1Asensor) is connected to the Bulletin 900-TC32, an offset of several degrees toseveral tenths of a degree can occur. For this reason, it may be desirable tooffset the readout value by 1-point or 2-point shift as described here.Note: 2-point shift can be carried out only on non-contact temperaturesensors, and cannot be set for other input types.Preparations1. Set to the temperature range matching the input specifications of thenon-contact temperature sensor (see Table A.B, List of Input Types). Thenon-contact infrared sensor is supported only in thermocouple inputtype Bulletin 900-TC32 controllers. (See Table 1.A.)Publication 900-UM003C-EN-E - January 2004

4-4 Parameter Adjustments and Application Considerations2. Prepare a thermometer (B) capable of measuring the temperature of thecontrol target (C) as shown in Figure 4.9 so that 1-point shift or 2-pointshift can be carried out.Figure 4.9 Configuration when Compensating a Non-Contact Temperature SensorNon-contacttemperaturesensor(C) Control target(B) Thermometer(A) 900-TC32Using the 1-Point Shift Method1. In the temperature control configuration shown in Figure 4.9, bring theset point to near the value at which the temperature of the control targetis to be controlled. Assume that the control target temperature (C) andthe control target temperature (B) match.Figure 4.102. Check the control target temperature (B) and the controller readout (A).Take the value from the following equation as the Input Shift Value, andconfigure the same numerical values to cns.

Parameter Adjustments and Application Considerations 4-53. After you have configured the 1-point input shift value, check controllerreadout (A) and control target temperature (B). If they are almost thesame, this completes temperature input shift.Figure 4.11 One-Point Temperature Input ShiftController readout (A)Temperature readoutafter shift (e.g. 120°C)Temperature readoutbefore shift (e.g. 110°C)After shiftInput shift value (e.g. 10°C)Before shift0Near set point(e.g. 120°C)Temperature readout ofcontrol target (B)Using the 2-Point Shift MethodUse the 2-point input shift method if you want to increase the accuracy of thereadout values across the range of a non-contact sensor.1. When using the 2-point shift method, shift the controller readout at twopoints: the first, near room temperature, and the second, near the valueat which the temperature of the control target is to be controlled.Therefore, for this procedure, bring the control target temperature tonear room temperature and to near the set point, and check controltarget temperature (B) and controller readout (A) (see Figure 4.9).2. Using equations 1 and 2 (p. 4-6), calculate the upper- and lower-limittemperature input shift values from the readout and temperature to beshifted that you obtained in step 1.Figure 4.12 shows the effect of shift by 2-point temperature input shift.Publication 900-UM003C-EN-E - January 2004

Although the input shift was carried out at two points, close to roomtemperature (ambient temperature), and near to the set point, you maywant to consider selecting points close to each end of the sensor rangeto improve accuracy across the full range of the sensor measurementrange.Note: Before selecting these values, check that they will not damage thecontrol application if applied.Publication 900-UM003C-EN-E - January 2004

Parameter Adjustments and Application Considerations 4-7EXAMPLEIn this example, we use the non-contact (infrared) sensortype K thermocouple 0…260°C specification. Therefore,this is a 2-point shift.YL and YH in equations 1 and 2 are set temperature lowerlimit (YL = 0°C) and set temperature upper limit (YH =260°C). Check the temperature of the control target.When the room temperature (X1) is 25°C, the readout onthe controller (Y1) is 40°C, and when the temperature nearthe set point (X2) is 110°C, the readout on the controller(Y2) becomes 105°C.Lower-limit temperature input shift value:Adjustment function groupLower-limittemperatureinput shift valuecnsl =0 – 40------------------- × {( 110 – 105) – ( 25 – 40)} + ( 25 – 40)=105 – 40–27.3°CUpper-limit temperature input shift value:Upper-limittemperatureinput shift valuecnsh =260 – 40------------------- × {( 110 – 105) – ( 25 – 40)} + ( 25 – 40)=105 – 40–52.7°CAlarm Functions/ParametersAlarm HysteresisYou can configure/program how much deviation (hysteresis) is allowed fromthe alarm value before the alarm comes on and resets.The hysteresis of alarm outputs, or when alarms are actually switchedON/OFF can be set as follows:Publication 900-UM003C-EN-E - January 2004

Note: The default is 0.2 EU (°C or °Fdepending on your units selection).Standby Alarm SequenceStandby alarm sequence is a function which allows you to configure the alarmoutputs to be temporarily disabled until after the first alarm condition occurs.From then on, the alarm output is active for all future alarm conditions.For example, in a standard heating application, if you used the standard lowalarm configuration, the alarm would be active as soon as you switch thecontroller ON. However, with standby sequence, the alarm output is disabledduring the first warm-up, and the temperature has to rise above the alarm setpoint before the alarm can become active. Then, if the temperature falls belowthe alarm set point, the output is active.RestartAs mentioned above, the standby sequence is canceled after the first real alarmclears. If desired, it can be restarted later by the Standby Sequence parameter(Advanced Setting function group). For details, see p. 5-31, Standby SequenceReset Method.Alarm LatchAlarm latch is a function where you can configure the alarm output onceturned ON to stay ON regardless of the process temperature.• The alarm latch function can be canceled by turning the power OFF.(Note, however, that it can also be canceled by switching to the InitialSetting function group, Communications Setting function group,Advanced Setting function group, or Calibration function group.Publication 900-UM003C-EN-E - January 2004

Parameter Functions and Definitions 5-13Temperature Input ShiftConditions of Use: The Input Type parameter must be configured as atemperature input. However, this excludes a non-contact temperature sensor.Function: Sometimes an error may exist between the measured temperature(PV) and the actual temperature at the control target. To offset this error, addyour configured input shift value to the input (PV). The result is displayed onthe controller as the new measurement value (PV) and used for control.Note: The entire input range is shifted by the input shift value (1-point shift).If the input shift value is set to –1°C, the process is controlled to a valueobtained by subtracting 1°C from the actual temperature (see Figure 4.2).Table 5.MConfigurable Range Units Default Value–199.9…+999.9 °C or °F 0.0Related ParameterInput Type (Initial Setting function group) (p. 5-20)Upper-Limit Temperature Input Shift Value,Lower-Limit Temperature Input Shift ValueConditions of Use: The Input Type parameter must be configured to thenon-contact temperature sensor.Publication 900-UM003C-EN-E - January 2004

5-14 Parameter Functions and DefinitionsFunction: Whereas the entire input range is shifted by a fixed value (1-pointshift) in the Temperature Input Shift parameter, this function shifts the inputrange by two points (2-point shift) at the upper and lower limits. 2-point shiftis useful for non-contact temperature sensors since the end point (0 andSPAN) difference is typically not the same. (See Figure 4.8.)This parameter sets input shift values for each of the upper and lower limits(2-point shift) of the input range.Table 5.NConfigurable Range Units Default Value–199.9…+999.9 °C or °F 0.0Related ParameterInput Type (Initial Setting function group) (p. 5-20)Proportional Band,Integral Time,Derivative TimeConditions of Use: The control method must be 2-PID control.Function: These three parameters configure the PID value parameters. Notethat PID is automatically set when either Auto-Tune (AT) and Self-Tune (ST)are executed.Proportional action: P refers to control in which the ManipulatedVariable/value (MV) is proportional to the deviation (control error).Integral action: I gives a control action that is proportional to the timeintegral of the control error. With proportional control, there is normally anoffset (control error). So, proportional action is used in combination withintegral action. As time passes, this control error disappears, and the set pointcomes to agree with the control temperature (process value).Publication 900-UM003C-EN-E - January 2004

Parameter Functions and Definitions 5-15Derivative action: D gives a control action that is proportional to the timederivative of the control error. As proportional control and integral controlcorrect for errors in the control result, the control system will be late inresponding to sudden changes in temperature. Derivative action enablescontrol that is proportional to a predicted process output to correct for futureerror.Table 5.OParameter Configurable Range Units Default ValueProportional Band 0.1…999.9 EU 8.0Integral Time 0…3999 Second 233Derivative Time 0…3999 Second 40Related ParameterAT Execute/Cancel (Adjustment function group) (p. 5-11)Cooling CoefficientConditions of Use: The control mode must be heating and cooling controlwith the 2-PID control method configured.Function: If the heating and cooling characteristics of the control target differgreatly, preventing satisfactory control characteristics from being obtained bythe same PID parameters, adjust the proportional band (P) at the controloutput 2 side by adding the cooling coefficient to balance control between thecontrol output 1 and control output 2 sides (see Figure 4.26).In the heating and cooling control mode, control output 2 side P is calculatedby the following formula to set the cooling coefficient:Table 5.PControl output 2 side P = Cooling coefficient x P (proportional band)Configurable Range Units Default Value0.01…99.99 None 1.00Related ParameterProportional Band (Adjustment function group) (p. 5-14)Publication 900-UM003C-EN-E - January 2004

Chapter 6Troubleshooting and Error IndicationWhen an error has occurred, the No. 1 display alternately indicates error codestogether with the current display item.This section describes how to check error codes on the display, and the actionsyou must take to remedy the problem.Input ErrorMeaning• The input value has exceeded the control range.– Platinum resistance thermometer, thermocouple input:Temperature setting lower limit –20°C to temperature setting upperlimit +20°C (temperature setting lower limit –40°F to temperaturesetting upper limit +40°F)– Non-contact input: Same as input indication range– Analog input: –5%…+105% of scaling rangeActionCheck the wiring of inputs for miswiring, loose connections, short-circuits,and the input type. If no abnormality is found in the wiring and input type,turn the power OFF then back ON again. If the display remains the same, theBulletin 900-TC32 must be repaired. If the display is restored, then a probablecause can be electrical noise affecting the control system. Check for sources ofelectrical noise.Operation at Error• After the error occurs, the error is displayed, and control outputfunctions turn OFF.• Alarm outputs function as if the upper limit value has been exceeded.6-1 Publication 900-UM003C-EN-E - January 2004

Appendix CCalibrationParameter StructureThe Bulletin 900-TC32 is correctly calibrated before it is shipped from thefactory, and normally need not be calibrated by the user. If, however, it mustbe calibrated by the user, use the parameters for calibrating temperature inputand analog input.Note: Rockwell Automation cannot ensure the results of calibration by theuser. Also, factory calibration data is overwritten with the user’s settings andthe factory. Default calibration settings cannot be returned after usercalibration.• To calibrate the Bulletin 900-TC32, enter the password 1201 at the Moveto Calibration Function Group parameter in the Advanced Settingfunction group. adj is displayed.• However, note that the Move to Calibration Function Group parametermight not be displayed when, for example, the user is calibrating theBulletin 900-TC32 for the first time. If this happens, set theInitial/Communications Protection parameter in the Protect functiongroup to 0 before moving to the Advanced Setting function group.• The calibration mode is quit by turning the power OFF.C-1 Publication 900-UM003C-EN-E - January 2004

C-2 Calibration• The parameters in the Calibration function group are structured asfollows:Figure 3.1Advanced setting function groupThese parameters are automatically moved according to the event input.Once the user has calibrated the Bulletin 900-TC32, a dot will be displayedwhen moving to the Calibration function group, to indicate that theBulletin 900-TC32 has already been calibrated by the user.Figure 3.2Dot is displayed.Publication 900-UM003C-EN-E - January 2004

Calibration C-3User CalibrationCalibrating InputWhen the user calibrates the Bulletin 900-TC32, the input type currentlyselected in parameters is calibrated. The following 24 input types can becalibrated.• Thermocouple: 14 types• Non-contact temperature sensor: 4 types• Analog input: 1 type• Platinum resistance thermometer: 5 typesRegistering Calibration DataThe new calibration data for each item is temporarily registered. It can beofficially registered as calibration data only when all items have been calibratedto new values. So, make sure to temporarily register all items when youcalibrate the Bulletin 900-TC32.When calibration data is registered, it is registered regardless of whether or notthe Bulletin 900-TC32 has been calibrated by the user.Prepare separate measuring devices and equipment for calibration. For detailson how to handle measuring devices and equipment, see the respectiveinstruction manuals.Calibrating Thermocouples• Calibrate according to the type of thermocouple, thermocouple 1 group(input types 0, 2, 5, 6, 8), and thermocouple 2 group (input types 1, 3, 4,7, 9, 10, 11, 12, 13, 14, 15, 17, 18).• When calibrating, do not cover the bottom of the Bulletin 900-TC32.Also, do not touch the input terminals (nos. 8 and 9) or compensatingconductor on the Bulletin 900-TC32.Publication 900-UM003C-EN-E - January 2004
