About the Nemesis Radar sensor
The sensor uses radio waves to detect the interface between two materials using
the principle of FMCW radar. This detection method has advantages over
ultrasonic waves in some applications. The Nemesis Radar Sensor has several
options to ensure optimal operation for various installations and process
requirements.
The Nemesis Radar Sensor is available with three aerial/antenna options and
three signalling interface options. Please contact Pulsar for advice on the optimal
model and installation accessories for your application.
PC software is available to allow setup and monitoring via either a local RS232
port or a remote connection using Modbus, Profibus or Hart modem.
The Pulsar Radar Levelstar is a matching controller which provides a complete
user interface for the Nemesis Radar Sensor and is recommended for most
installations.
Page 2

Functional Description
A simplified diagram of the Nemesis Radar Sensor is shown below.
The Frequency Modulated Continuous Wave, Radio Detection And Ranging
principle has been developed over many years to accurately measure targets at
relatively short distances. The transmitter section generates a radio signal that is
linearly swept over the 8.9 to 10.1 GHz frequency range. This signal is beamed
by the aerial/antenna towards the target or material where it is reflected back
towards the sensor’s receiver. The receiver mixes a sample of the transmitted
signal with the received signal. The receiver output is a low frequency, linearly
dependent on the target distance. This ‘beat’ frequency is generated by the
Doppler effect and is stable and predictable.
The Doppler beat frequency is amplified, filtered and then digitised by an
Analogue-to-Digital converter (A2D). The following Digital Signal Processor
(DSP) performs a frequency analysis of the received signal to determine the target
distance and strength. The output of this Fast-Fourier Transform (FFT) process is
then passed to the post-processing algorithms to identify the correct target, which
is the contents of the container or process level.
The target-finding algorithms have been developed and optimised by Pulsar over
many years experience to reliably identify and track process levels for liquids,
sludges, powders and solids.
The Nemesis Radar Sensor signal interface communicates the measurement
information to other process equipment or the Pulsar radar LevelStar controller.

This device shall be installed and operated in a completely enclosed container to
prevent RF emission which otherwise can interfere with aeronautical navigation.
Installation shall be done by trained installers, in strict compliance with the
manufacturer’s instructions.
The use of this device is on a “no-interference, no-protection” basis. That is, the
user shall accept operations of high-powered radar in the same frequency band
which may interfere with or damage this device. On the other hand, devices found
to interfere with primary licensing operations will be required to be removed at
the user’s expense.
Changes or modifications not expressly approved by the manufacturer could void
the user’s authority to operate the equipment
RF exposure: The output power of the sensor is 1 milli-Watt. This is well below
established risk levels (Specific Absorption Rate) for RF exposure. Additionally
the equipment is intended for installation within sealed containers.

Chapter 2
Installation Guide
Power Supply Requirements
The Nemesis Radar sensor operates from a DC supply of 20 to 28V DC. The peak
power is 15W and the average power is 7W. Typical peak current draw is;
750mA @ 20V 630mA @ 24V 540mA @ 28V
When calculating the cable requirements the peak current figure should be used
and the voltage drop in the cable should be considered.
General Installation and Location
The Nemesis Radar Sensor is intended for operation within enclosed tanks or
silos. The enclosure should typically be metal or concrete. Thin plastic or fibreglass
would not normally be acceptable because the Radar emissions must not
escape or leak through the enclosure.
Outdoor operation is not permissible.
The sensor should be mounted in a manner described by the following diagrams.
The sensor shouldn’t be situated dead centre of a vessel because this makes
internal reflections worse.
The flanges should be sealed to Radio Frequency (RF) energy, typically by
adding a braided cable seal under the mounting flange(s). For a 5mm diameter
braid seal, typically common co-axial cable is OK after removing the outer
sheath, for example:
Belden RG6, Propower CBBR0123, CF0003, CF0094
Conductive graphite grease may also be employed to seal tight gaps and large
bolt threads. Many types of ‘graphite grease’ are not conductive; the following
type has been tested and proven effective by the manufacturer:
Fuchs Lubritech ZX-13
Ensure that the sensor body is not exposed to temperatures above +70 degrees
Centigrade / +158 degrees Farenheit. Where higher temperatures are expected
contact the manufacturer for advice and refer to the external mounting methods
described by the following diagrams.

Cable.
Pulsar can supply a four-core screened cable suitable for most installations up to
85m from the power supply or controller. When calculating the voltage drop
along the cable, remember the ambient temperature and that current draw
increases at lower voltages.
Typical specification at 50 o C / 122 o F ambient, based on 4V loss in the cable;
Maximum cable run: Each conductor: Conductor area:
85m / 280’ 16/0.2mm 0.5mm 2 , standard
128m / 420’ 24/0.2mm 0.75mm 2
170m / 560’ 32/0.2mm 1mm 2
Cable Preparation
For installation of the cable please refer to the mounting options shown in the
previous diagrams, as the cable may need routing via the mounting flange(s),
aimer and conduit before finalising cable installation in the sensor as described
below.
The cable described is standard Pulsar four core screened cable. Identification

How To Use Your Nemesis Radar Sensor
In order to view or change parameter values one of the following methods
must be used:
PC Handheld Programmer (Standard)
Your Nemesis Radar Sensor comes complete with the Blackbox PC
Handheld Programmer software, contained on CD. Insert the CD into the
CD drive of the PC intended to be used to carry out the programming of the
Nemesis Radar Sensor and install the software, following the on screen
instructions. Once the software is installed connect the computer via its
serial port to the Nemesis Radar Sensor RS232 serial interface RJ11
connector, located on the terminal board underneath Nemesis Radar
Sensor’s top cap, to access remove the cap as per Chapter 2 Installation
Guide – Cable Preparation.
Double click the ‘Handheld Programmer’ icon, installed on your desktop
and the PC will automatically connect to the Nemesis Radar Sensor. Once
connected you will briefly see the message illustrated on the display below
which, after connecting successfully, will then change to display the current
measurement, dependent on mode and measurement unit's chosen. When
using the PC Handheld Programmer software, keypad input can be achieved
by using a ‘mouse’ or similar device to place the cursor over the relevant
key followed by a ‘left’ click, alternatively numeric detail can be entered
directly from the PC keyboard as can ‘ENTER’ and ‘CANCEL’ (Esc. Key).
Page 33

Communication Port Configuration
If the PC Handheld Programmer fails to connect to the Nemesis Radar
Sensor you may need to change the communications port that is being
used, to do this ‘right click’ on the PC Handheld Programmer keypad and
a ‘pop up’ menu will appear allowing you to select the appropriate
communications port.
Handheld Communicator (Optional)
The optional Handheld communicator can be used to program any number
of Nemesis Radar Sensors and works in a similar way to the PC Software.
Connect the Handheld Communicator, with the cable supplied, to the RS232
interface via the RJ11 connector, located on the terminal board underneath
Nemesis Radar Sensor’s top cap, to access remove the cap as per Chapter 2
Installation Guide – Cable Preparation.
Once connected you will briefly see a message, similar to that as seen when
using the PC Software which, after connecting successfully, will then
change to display the current measurement, dependent on mode and
measurement unit's chosen.
Page 34

Radar Level Star (Optional)
When installed and connected to the optional Radar Level Star, the Nemesis
Radar Sensor can be programmed directly via the Level Star’s integral
keypad. See Radar Level Star manual for full details
Operating the Controls
Display
The display of both the PC Handheld Communicator and the Hand Held
Calibrator (optional) is identical.
While in the Run Mode it will display the current level reading and its units
of measure, along with status messages with regards to the Transducer, Echo
reception and Fail Safe Mode. When in the Program mode the display is
used to read information on the Menu System, Parameter Number and

Page 36

Menu Keys
The menu keys are used to navigate around the built in menu system and
have the following functions:
Menu Key
Function
1) Arrow keys for moving left and right around the menu
system.
2) Used in test mode to simulate the level moving up and
down.
1) Used to confirm each action (for example select a
menu option) or when entering a parameter number or
value.
2) Used to confirm questions asked by your Nemesis
Radar Sensor such as before restoring factory defaults.
Used to navigate up a level in the menu system, and back
to run mode.
Used to cancel a value entered in error.
Numeric Keys
These keys are used for entering numerical information during
programming.
Page 37

There are two main operating modes for your Nemesis Radar Sensor, Run
Mode and Program Mode. There is also a Test Mode, used for checking
the set-up. All modes are now described.
Run Mode
This mode is used once the Nemesis Radar Sensor has been set up in
program mode. It is also the default mode that the unit reverts to when it
resumes operation after a power failure.
When the Nemesis Radar Sensor is switched on for the first time, it will
provide an output proportional to the distance from the transducer to the
target, in metres. All relays by default are switched off.
If either the PC Handheld Programmer software (standard), or the Hand
Held Calibrator (optional), are connected to the Nemesis Radar Sensor, via
the RS232 interface, while the Nemesis Radar Sensor is in the RUN mode
then the current measurement will be displayed, dependent on mode and
measurement units chosen.
Program Mode
This mode is used to set up the Nemesis Radar Sensor or change
information already set. You must use either the PC Handheld software
supplied (standard), or alternatively the unit can be set up with a Hand Held
Calibrator (optional), both of which must be connected to the Nemesis
Radar Sensor via the RS 232 Serial Interface.
Entering a value for each of the parameters that are relevant to your
application provides all the programming information.
How to Access Program Mode
To enter program mode, you simply enter the passcode, via the keypad on
the PC Handheld Programmer software (standard), or Hand Held Calibrator
(optional), followed by the ENTER key. The default passcode is 1997, so
you would press the following:
Page 38

Note
There is a time-out period of 15 minutes when in program mode, after
which time run mode will be resumed if you do not press any keys.
There are two means of editing parameters, directly or using the menu
system. Each is now described.
Using The Menu System
The menu system has been designed to make the changing of parameters
very simple. There are two levels of menu: Main Menu and Sub Menu.
On the display there is a line of text that shows the menu system. Pressing
the arrow keys scrolls the display between the top-level menu items, (as
shown below, starting at Application).

Test
Service
As you press the cursor keys to scroll left and right between these, you can
press ENTER at any time to select it and take you to the sub-menu.
Each of these options, along with their sub-menus are described in Chapter
5, Parameter Guide. When you move down into the sub-menu, you can
scroll round using the arrow keys, press ENTER to go to the required section
of parameters.
Once you have reached the relevant section, scroll through the parameters,
and enter the necessary information. To enter the information, use the
numeric keys and press ENTER and you will see the message “Saved!”, if
you press CANCEL, then no change will be made, and the message
“Unchanged!!” will be displayed.
Page 39

When you have finished, press CANCEL to go back to the previous level.
When you have reached the top level, then the Nemesis Radar Sensor will
ask for confirmation before allowing you to go back into run mode. This is
done by pressing ENTER at the display prompt.
Directly Editing Parameters
If you already know the number of the parameter, that you wish to look at or
edit, simply type the number in at any time while you are in the menu
system. Thus, if you are in either the menu or sub-menu level by pressing a
numeric key, you can enter the parameter number directly and jump straight
there. You cannot type a parameter number while at parameter level, only at
one of the two menu levels.
When you are at a parameter, the text line rotates automatically displaying
the parameter name, number, the applicable units and the maximum and
minimum figure you can enter. The top line shows the value you are setting.
Once you have accessed a parameter, you can just look at it, or change it.
Once a parameter has been changed, press ENTER and you will see the
message “Saved!” If you press CANCEL, then no change will be made, and
the message “Unchanged!!” will be displayed.
TIP
You can jump straight to the
last parameter you edited, by
pressing ‘+/-’ when you first
enter program mode.
Test Mode
Test mode is used to simulate the application and confirm that all parameters
and relay setpoints have been entered as expected. During simulation, there
is a choice of whether the relays will physically change state (hard
simulation) or not (soft simulation), the LED’s will always change state to
indicate that the relay setpoints have been activated, and the output will
change in accordance to the chosen mode of operation. If you wish to test
the logic of the system that the relays are connected to then select hard
simulation, but if you don’t want to change the relay state, then select a
soft simulation.
Page 40

There are two simulation modes, automatic and manual. Automatic
simulation will move the level up and down between empty level and
maximum span, whereas manual simulation will allow you to move the
level up and down using the arrow keys.
To enter simulation, first go to program mode. Then, using the menu
system, select menu item ‘Test’ then sub-menu item ‘Simulation’. Simply
change the value of the parameter P980 to one of the following:
1= Manual
2= Automatic
To return to program mode, press CANCEL and test mode will end.
When in manual simulation, by default test mode will move the level by
0.25m steps. Altering the increment (P981) will change this value.
In automatic mode, the rate at which the level moves up and down is set by
the increment (P981) in metres. To make the simulated level move slower,
decrease the value in increment (P981). To make the simulated level move
faster, increase the value in increment (P981).
Using the RS232 Serial Interface
The RS232 serial interface is used to program the Nemesis Radar Sensor,
and communicate between the Nemesis Radar Sensor and a PC using the
optional Nemesis PC and other associated Pulsar software packages, to
obtain information such as data logging and view echo traces upload,
download and save parameter files. In addition it can also be used to control
or obtain information using a standard PC or other computer based
equipment. To do so, the settings for control are as follows: baud rate
19,200, 8 data bits, no parity, 1 stop bits.
The device should be connected to the RS232 Interface via the RJ11
connector as shown in Chapter 2 Installation.

Parameter Defaults
Factory Defaults
Factory Defaults
When first installing the Nemesis Radar Sensor, or subsequently
moving or using the unit on a new application, before proceeding to
program the unit for its intended application it is recommended that
you ensure that all parameters are at their default values by
completing a Factory Defaults P930, as described in Chapter 5
Parameter Guide.
When you first switch the Nemesis Radar Sensor on it will provide an
output proportional to the distance from the sensor the surface of the
material.
The date (P931) and time (P932) in the Nemesis Radar Sensor were set at
the factory, but may need checking, and amending if, for example the
application is in a time zone other than GMT, see Chapter 5 Parameter
Guide for full details.
TIP
In some applications it is simplest to empty the
vessel, take a reading from the Nemesis Radar
Sensor for distance and then setup the empty
level to this figure.
Once you are satisfied with the installation, and the Nemesis Radar Sensor is
reading what you would expect in terms of distance from the face of the
transducer to the material level, then you can proceed with programming,
for the intended application. It is sensible to program all of the required
parameters at the same time. The system will be then set-up.
Note that the span is automatically calculated from the empty level, so the
empty level should be entered first.

P103 Waveguide Extension
This parameter sets the extension length of the waveguide. Default is 0.
The effective distance change is automatically calculated by the software.
Page 55

Distances
P104 Measurement Units
This parameter sets the units you want to use for programming and display
Option
Description
1 = metres (Default) All units of measure are METRES
2 = cm All units of measure are CENTIMETRES
3 = mm All units of measure are MILLIMETRES
4 = feet All units of measure are FEET
5 = inches All units of measure are INCHES
P105 Empty Level
This parameter is to be set to the maximum distance from the flange of the
sensor to the empty point, in P104 Measurement Units.
Note this value affects span as well, (see important information below), so
should be set before span.
P106 Span
This parameter should be set to the maximum distance from the Empty
Level (P105) to the maximum material level. It is automatically set to be
equal to the Empty Level (P105) less the Near Blanking distance (P107),
when you set the empty level.
P107 Near Blanking Distance
This parameter is the distance from the flange of the sensor, and is pre-set to
the minimum value. It should not be set to less than this figure, but can be
increased, typically to ignore close in obstructions. The default is defined by
the aerial/antenna type.
P108 Far Blanking Distance
This is the distance (as a percentage of empty level P105) beyond the
empty point that the unit will be able to measure, and by default is pre-set to
20% of the empty level.
If the surface being monitored can extend beyond the Empty Level (P105)
then the far blanking distance can be increased to a maximum of 100% of
empty level provided it does not exceed the maximum range of the sensor.
This parameter is always entered as a % of empty level.
Page 56

The following diagram illustrates the above parameter definitions and their
reference point.

Display Parameters
Options
P801 Decimal Places
This parameter determines the number of decimal places on the reading
during run mode.
Minimum = 0 (No decimal places), Maximum 3 = (3 decimal Places)
Default = 2 (2 decimal Places)
Failsafe
P808 Fail-safe Mode
By default, if a fail-safe condition occurs, then the display, relays and the
mA output are held at their last known values until a valid reading is
obtained.
If required, then you can change this so that the unit goes to high (100% of
span), or low (empty) as follows:
Option
Description
1 = Known (Default) Remain at the last known value
2 = High Will fail to the high value (100% of Span).
3 = Low Will fail to the low value (empty)
See Also P840 mA Output Fail-safe
Important Information
In the event of a fail-safe condition occurring, the mA Output can be
configured to fail to a condition which is independent of each other. To set
independent mA Output Failsafe see P840.
P809 Fail-safe Time
In the event of a fail-safe condition the fail safe timer determines the time
before fail-safe mode is activated. Default = 2mins
If the timer activates, the unit goes into fail-safe, as determined by P808
and P840 (mA Output). When a valid measurement is obtained the mA
output is restored and the timer reset.
Page 60

mA Output Parameters
Range
P830 mA Range
This parameter determines the range of the mA output, from the following.
Option
Description
0= Off mA output disabled.
1= 4 to 20 mA mA output directly proportional to the mA mode
(Default) (P831), so if the reading is 0% the output is 4 mA. If
the reading is 100% the output is 20 mA.
2= 20 to 4 mA mA output inversely proportional to the mA mode
(P831), so if the reading is 0% the output is 20 mA. If
the reading is 100% the output is 4 mA.
Operation
P831 mA Mode
This parameter determines how the mA Output relates to what is measured.
By default it operates exactly the same as the display (P100), but it can be
set to operate as follows:
Option
Description
0 = Default mA output relative to Mode P100
1 = Distance mA output relative to distance.
2 = Level mA output relative to level.
3 = Space mA output is relative to space.
4 = Volume mA output is relative to volume.
Page 61

Setpoint
Limits
By default the mA Output will represent the empty (4mA) and 100% of the
operational span (20mA), but you may wish to have the output represent a
section of the operational span. For example, the application has an
operational span of 6 metres but output is to represent empty (4mA) to a
level of 5 metres (20mA). If so P834 (Low Level) should be set to 0.00
metres and P835 (High Level) should be set to 5 metres.
P834 mA Low Level
This parameter sets the level, distance or space, depending on the selected
mA Out Mode (P831) at which the low mA output will occur (4mA)
Default = 0.000m
P835 mA High Level
This parameter sets the level, distance or space, depending on the selected
mA Out Mode (P831) at which the high mA output will occur (20mA).
Default = 63.500m
P836 mA Low Limit
This parameter sets the lowest level that the mA output will drop to, the
default is 0mA, but you can override this if the device you connect to cannot
for example accept less than 4mA. Default = 0.00mA
P837 mA High Limit
This parameter sets the highest level that the mA output will rise to, the
default is 20 mA, but you can override this if the device you connect to
cannot for example accept more than 18 mA, yet you want to use the 0-20
mA range. Default = 20.00mA
Page 62

Trim
P838 mA Low Trim
If the device you are connected to is not calibrated, and not showing the
correct low value (reading), then you can trim it using this parameter. You
can either type in the offset directly, or use the arrow keys to move the
output up and down until you get the expected result (reading) on the device
that is connected.
P839 mA High Trim
If the device you are connected to is not calibrated, and not showing the
correct high value (reading), then you can trim it using this parameter. You
can either type in the offset directly, or use the arrow keys to move the
output up and down until you get the expected result (reading) on the device
that is connected.
Failsafe
P840 mA Fail-safe Mode
This parameter determines what happens to the mA output in the event of
the unit going into fail-safe mode. The default is to do the same as the
system fail-safe (P808), but this can be overridden to force the mA output
to an independent fail-safe mode as follows:
Option
Description
0 = Default mA output will fail as per P808.
1 = Hold mA output will retain its last known value.
2 = Low mA output will fail to its low (4mA)
condition.
3 = High mA output will fail to its high (20mA)
condition.
4 = Very Low mA output will fail to its low fault
(3.5mA) condition.
5 = Very High mA output will fail to its high fault
(22mA) condition.
Page 63

Compensation Parameters
Offset
P851 Measurement Offset
The value of this parameter is added to the measured distance, in
Measurement Units (P104).
This Offset will be added to the level, as derived from the radar sensor, and
will affect everything including the mA output.
Stability Parameters
Damping
Filters
Damping is used to damp the display, to enable it to keep up with the
process but ignore minor surface fluctuations.
P870 Fill Damping
This parameter determines the maximum rate at which the unit will
respond to an increase in level. It should be set slightly higher than the
maximum vessel fill rate. Default = 10m/min
P871 Empty Damping
This parameter determines the maximum rate at which the unit will
respond to a decrease in level. It should be set slightly higher than the
maximum vessel empty rate. Default = 10m/min
The following three parameters can be used to filter out unwanted changes
of level caused by a ‘rippled’ or agitated surface.
P881 Fixed Distance
This parameter determines the width of gate to be used in tracking an echo
and under normal circumstances will not require changing, but it can be
increased in the cases where the surface is moving extremely fast (in excess
of 10m/min) to ensure smooth processing of the changing level.
Page 64

P882 Process Filter
This parameter determines the number of ‘cycles’ that will be taken before a
change in level is processed and the display updated.
Option
Description
1 = Fast level will be updated every cycle
2 = Medium level will be updated every 8 cycles
3 = Slow (Default) level will be updated every 16 cycles
Echo Processing Parameters
Sensor Status
P900 Sensor Status
This parameter shows the current state of the radar sensor as follows;
Option
Description
0= OK Sensor working correctly.
1= DSP Data Error Sensor fault. Data from DSP is incorrect
2= DSP Timed out Sensor fault. No response from DSP board
P901 Echo Confidence
This parameter displays the most recent echo confidence from the radar
sensor. It is useful to help find the best mounting location for the sensor,
where you should aim to get the highest figure. It is a percentage of
confidence that the echo reporting the level is the correct one.
P902 Echo Strength
This parameter displays the most recent echo strength figure for the sensor,
where a higher figure indicates a better returned echo.
P903 Average Noise
This is the mean noise reading for the sensor. It is measured while the sensor
is transmitting, and gives an indication of the average amount of electrical
noise present in the application environment.
P904 Peak Noise
This is the peak noise reading for the sensor. It is measured while the
transducer is transmitting, and gives an indication of the maximum amount
of electrical noise present in the application environment.
Page 65

P905 Sensitivity
This is the minimum level for datem.
P906 Side Clearance
This is the margin on either side of the echoes to allow for fluctuation in
receiving signals.
System Parameters
Passcode
P921 Enable Code
Enables the passcode (P922), which means the passcode must be entered to
go into program mode. If disabled (set to 0), then no passcode is required,
and ENTER is used to enter program mode. Default =1 (Enabled)
P922 Passcode
This is the passcode that must be used to enter program mode. The default
is 1997, but this can be changed to another value from 0 to 9999.
System Information
The following three parameters do not affect how the unit performs, but details,
contained in them may be required by Pulsar when making technical enquiries.
P926 Software Revision
This parameter will display the current software revision. It is read only.
P927 Hardware Revision
This parameter will display the current hardware revision. It is read only.
P928 Serial Number
This parameter will display the serial number of the unit. It is read only.
P929 Site Identification
This parameter allows you to give each unit an individual reference number,
for identification purposes. You can set any number between 1 and 99999.
Page 66

P930 Factory Defaults
This parameter resets all parameter values to the original Factory Set values
that were installed when the unit was tested, before despatch to you.
To reset parameters, enter 1 (Yes), and press ENTER, then you will see a
message “Entr if sure”, you should press ENTER again. If you press any
other key at this point, the parameters will not be reset, and you will see a
message confirming this.
Once you have done this, program the unit for the desired application.
Date & Time
The date and time is used, to control specific relay functions and date stamp
certain events that are contained in the Data Logs. It is also used in
conjunction with the system watchdog that keeps an eye on the times the
unit has started.
P931 Date
This parameter display the current date, in the format as set by P933 (Date
Format), and can be reset if required.
P932 Time
This parameter displays the current time and can be reset if required, in the
format HH: MM (24-hour format). This is set initially at the factory for UK
time.
P933 Date Format
This parameter allows you to alter the format that the date is displayed to
your choice of DD: MM: YY, MM: DD: YY or YY: MM: DD. The default
is DD: MM: YY.

Test Parameters
Simulation
P980 Simulate
Test mode is used to simulate the application and confirm that all parameters
and mA output have been entered as expected. There are two simulation
modes, automatic and manual. Automatic simulation will move the level
up and down between empty level, if you wish to change the direction of the
level movement, this can be done by using the arrow keys. In manual
simulation, using the arrow keys will allow you to move the level up and
down as required.
The choices for you to enter are as follows.
1= Manual simulation
2= Automatic simulation
To return to program mode, press CANCEL and test mode will end.
P981 Increment
By default, simulation mode will move by 0.1m steps in manual simulation
and by 0.1m/min in automatic simulation. Altering the increment can change
this value.
Hardware
P992 mA Out Test
This parameter will allow you to force a specified current on the mA output,
to test the equipment that it is connected to, and to make sure the unit is
working correctly. The figure you enter will be generated by the mA output.

Troubleshooting
This section describes many common symptoms, with suggestions as to
what to do.
Symptom
Incorrect reading being displayed for
current level.
Material level is consistently incorrect
by the same amount.
Signal level is low and jumps in level.
Signal level is high with spurious
echoes
What to Do
Measure actual distance from
sensor head to surface of
material. Enter Program Mode
and directly access P21 (Set
Distance) type in the
measured distance, ENTER,
ENTER again when
prompted, wait until SET
displayed and return to Run
Mode, display should now
update to correct reading.
Check empty level, (P105)
and measurement offset
(P851).
Increase gain parameter P31
(Please seek advice from
Pulsar before adjusting)
Reduce gain parameter P31
(Please seek advice from
Pulsar before adjusting)
