3. PRODUCT INTRODUCTION
Our digital panel meters are versatile, cost effective solutions to a wide variety of monitoring
and control applications. Depending on the choice of signal conditioner, they are easily set up
for an accurate display of temperature, pressure, flow, weight, voltage or current, all in
appropriate engineering units and with zero and span adjustment when needed. Setup can be
via front panel pushbuttons or the meter’s serial interface. Selective security lockout of the
front panel keys protects against accidental changes to meter setup.
High read rates up to 60 per second (50 for 50 Hz operation) are made possible by
Concurrent Slope Conversion (Pat 5,262,780), which integrates the signal over an AC power
line cycle for maximum noise rejection. High read rates provide accurate peak and valley
capture, and quick response for control applications. An adaptive digital filter supplies a time
constant for the encountered signal noise level, yet responds rapidly to changes that exceed a
selected threshold. Self-calibration occurs automatically after every 17th reading.
The standard power supply is a high-efficiency switching unit that operates from AC or DC,
and allows the meters to be powered from worldwide AC without changes. A low-voltage
supply is optional for power from 10-48V batteries or from 12-30 Vac. Both supplies provide an
isolated 5, 10 or 24Vdc transducer excitation output.
The meter case conforms to the 1/8 DIN size standard. It is made of high impact, 94V-0 ULrated plastic and is watertight to NEMA-4 (IP65) when panel mounted. Mounting is from the
front of the panel and requires less than 110 mm behind the panel. Power and signal wiring is
via removable plugs conforming to UL61010C safety standards. All output options are isolated
from meter and power ground to 250 Vac.
Extended meter versions can linearize nonlinear inputs. Up to 180 data points may be
linearized by a computer program that stores setup parameters in nonvolatile memory.
Extended meters can also display rate of change, for example to display flow rate based on
changing tank level.
Alarm or setpoint control is provided by an optional relay board with two or four Form C 8A
mechanical relays or two or four Form A 120 mA solid state relays. The setpoints may be
latching or non-latching, be energized above or below the setpoint, or operate in a fail-safe
mode. The relays can operate from the filtered signal to reduce relay chatter or from the
unfiltered signal for fastest response. Snubber circuits and a programmable relay switching
time delay extend relay contact life.
An isolated analog output of 4-20 mA, 0-20 mA, 0-10V or -10 to +10V can be provided by an
optional analog output board. The output is linearized to the display and can operate from the
filtered or unfiltered signal input. It can be scaled via front panel pushbuttons or the meter’s
serial interface.
Ethernet USB, RS232, or RS485 (2-wire half-duplex or 4-wire full-duplex) serial communications options are available with the Modbus protocol or a simpler custom ASCII protocol.
Modbus operation includes RTU or ASCII modes, up to 247 digital addresses, and up to 32
devices per RS485 line without a repeater. Ethernet-to-RS485 and USB-to-RS485 converter
boards allow a meter to be interfaced to a PC and to multiple meters on an RS485 network.
Meter programming can be via the meter’s front panel or a PC running Windows based
Instrument Setup Software (serial interface option required).

8. FRONT PANEL SETUP KEYS
Meter Front Panel
There are four front panel keys, which change function for the Run Mode and Menu Mode,
effectively becoming eight keys. The keys are labeled with alphanumeric captions (MENU,
PEAK, RESET, ALARMS) for the Run Mode and with symbols (
right triangle,
FRONT PANEL LOCKOUT
up triangle,
left arrow) for the Menu Mode.
right arrow,
The Menu Mode will not work with most meters as received from the factory, since all menu
items have been disabled in software and a lockout jumper is in place. That jumper needs to
be removed for the Menu Mode to work, and menu items under Loc 1, Loc 2 and Loc 3 then
need to be set to "0" via the front panel for these menu items to be unlocked See Section 9.
The paragraphs below assume that all menu items have been unlocked.
MENU MODE KEY ACTION
In the Menu Mode, pressing a key momentarily advances to the next menu item. Holding
down a key automatically advances through multiple menu items for fast menu navigation.
KEYS IN RUN MODE
MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing
MENU repeatedly will step the meter through the various menu items (if these have not
been locked out) and then back to the Run Mode.
PEAK Key. Pressing PEAK normally causes the peak value of the input signal to be
displayed. The peak display then blinks to differentiate it from the normal present value
display. Pressing PEAK again returns the display to the present value. The PEAK key
can also be programmed to display Valley, alternating Peak or Valley, or to Tare the
reading to zero. When Peak or Valley is selected, periodic horizontals bars at the top of
the display indicate Peak, and periodic horizontals bars at the bottom indicate Valley.
RESET Key. Pressing RESET with PEAK resets peak and valley values. Pressing
RESET with ALARMS resets latched alarms. Pressing RESET with MENU performs a
meter reset (same as power on). Meter reset can also be applied via a rear panel
connect or a serial ASCII command.
ALARMS Key. Pressing ALARMS once displays the setpoint for Alarm 1. Pressing it
again displays the setpoint for Alarm 2. Pressing it again returns to the present value.

9. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of meter operation, any or all
menu items may be disabled or "locked out" so that they are no
longer accessible from the front panel. Each function to be
disabled can be set to "1" under menu headers Loc 1-3, while
each function to be enabled can be set to "0." Access to the
menu headers Loc 1-3 can in turn be locked out by installing a
hardware jumper on the power supply board. With the jumper
installed, the operator only has access to previously enable
menu items, not to the menu headers Loc 1-3 and hence not to
the menu items below. With the jumper removed, the operator
has access to menu headers Loc 1-3 and hence to the menu
items below.
SETTING HARDWARE LOCKOUT JUMPER
To access the lockout jumper, remove the rear panel per Section
9 and locate jumper “a” in the lower portion of the power supply
board next to the input connectors (see figure at right).
Check lockout status. Many Laurel meters are shipped with lockouts in place.
This causes menu items described later in this manual not to appear.
SETTING SOFTWARE LOCKOUTS
To set up a meter, it may be necessary to enable
menu items by setting lockout digits to “0”. Following
setup, reset the digits to "1" if you do not want the
menu item to be changed by an operator.

10. METER SCALING THEORY
User scalability is a standard feature of all of our analog input meters, with the exception of
thermocouple and RTD meters. It allows electrical signals to be converted to readings in
engineering units. These readings can have up to 5 digits, a user specified decimal point,
and a user specified polarity. For example, the same 4-20 mA signal from a pressure
transducer can be scaled for display as 80.00 to 120.00 psi or 551.6 to 827.4 kPa.
Three scaling methods are user selectable under the meter SEtuP programming item:
1) Scale and Offset Method, which specifies a straight line of the type y = mx + b
2) Coordinates of 2 Points Method, which fits a straight line between two data points (low
in, low read, and high in, high read).
3) Reading Coordinates of 2 Points Method, which uses actual signal inputs instead of
manually entered low and high input signals.
Select the scaling method which is most convenient. If you know that the straight line
passes through zero, you may wish to use the Zero and Offset Method by entering an offset
of zero and the required scale factor. If you are using calibrated 4-20 mA transducer, you
may wish to use the Coordinates of 2 Points Method by entering the readings for 4 mA and
20 mA. If you have a load cell meter and a known 50.000 kg weight, you may to use the
Reading Coordinates of 2 Points Method by entering 0.0000 for no load and 50.000 with the
reference weight in place.
Counts, which are properly rounded integers, are used for scaling regardless of the scaling
method used. The decimal point is not used in calculations, only as a decoration.
The number of inputs counts is the number generated by analog-to-digital conversion.
The maximum 20,000 for the signal span from 0 to full scale (FS), except as noted. This
means that one count is 1 mA for the 20.000 mA scale (which includes 4-20 mA), and 0.01V
for the 200.00V scale. Exceptions are as follows. With the load cell signal conditioner, one
count is 10 µV for the 250.00 mV and 500.00 mV scales. With the DC signal conditioner,
one count is 0.1V for the 300.0V and 600.0V scales, since these are really the 2000.0V
scale, and one count is 1 mA for the 5.000A scale, since this is really the 20.000A scale.
Our meter cannot be rated for these high ranges.
The number of output counts is the number that is displayed on the meter, is output as
serial data, is used to generate the meter’s analog output, and is used for relay setpoint
comparisons. The number of output counts is obtained by multiplying the number of input
counts by the scale factor SCALE and adding the offset value OFFst .
To increase output resolution and add displayed digits after the decimal point, multiply the
input counts by a factor of 10 for each additional digit, then move the decimal point one
position to the left for each additional digit. For example, if you want to display 517.13 kg
instead of 517 kg from a load cell input, increase the scale factor by a factor of 100 to
increase the counts to 51713, then move the decimal point to the left by two positions. This
change in scaling can also be achieved by entering larger readout numbers using the Coordinates of 2 Points Method or Reading Coordinates of 2 Points Method.
To decrease resolution, for example to display 15,547 mv as 15.5V, divide the scale factor
by 10 for each digit to be eliminated. For this example, apply a scale factor of 0.01 to
change the counts to 155, and move the decimal point one position to the left.

11. DC VOLTS, AMPS, PROCESS, DC RATIO
The DC Volts, Amps, Process and Strain meters utilize the DC signal conditioner board, which
needs to be configured via jumpers for the desired voltage or current range. All signal ranges
are factory calibrated with calibration factors stored in EEPROM. The meter software
recognizes the board and will bring up the appropriate menu items for it; however, it does not
recognize the jumper settings. Please see further manual sections for setup of relay outputs,
analog output, communications, and excitation output.

Notes: Jumpers are to cover gaps marked by a letter. Store spare jumpers on unused jumper
posts. Please contact us for board revisions earlier than Q.
For DC voltmeters & ammeters, a scale factor of 1 and an offset of 0 are used for direct
readings in (milli)volts or (milli)amperes. Decimal point selection does not affect the displayed
digits. A full scale reading is 20000 counts. This may be displayed as 20.000 mA or 20000 µA.
Use with a current shunt requires a scale factor to be set. For example, for a 500-100 (500A,
100 mV) shunt, divide 5000 (the desired full scale display with 0.1A resolution) by 10000
(displayed value with 100 mV when the scale factor is 1.0) for a scale factor of 0.5.

For process & strain meters, scaling is normally set up from the front panel using the
keys, but can also be set up via a serial connection and Windows based Instrument Setup
Software (available at no charge). A full scale reading is 20000 counts. Three scaling methods
are selectable: 1) Scale and offset, 2) Coordinates of 2 points, and 3) Reading coordinates of 2
points. Only menu items applicable to the selected method are presented.
For DC ratio (or potentiometer follower) operation, the meter displays the ratio of the signal
and applied excitation voltage, so that the reading is unaffected by changes in the excitation
voltage. This capability is used for resistive bridge sensors and voltage dividers, such as
potentiometers which track wiper position. To implement, set _InPut to _rAtio (next page). For
bridges and potentiometers, make P5 Signal Input connections as shown under Connector
Wiring Information (page 6).

Reading Coordinates of 2 Points Scaling Method
This scaling method applies a straight line fit between two points, which are based on actual
transducer signals. A low input signal, such as the signal with zero weight, and a high input
signal, such as the signal with a known weight, are applied to the meter. The corresponding
desired low and high readings are then entered from the front panel. The meter applies straight
line fit between these low and high calibration points. This scaling method has the advantage
of calibrating the transducer and meter as a system. The actual voltages or currents at the two
endpoints do not need to be known. This method can be used with DC, process and load cell
meters when known inputs are available. It is also available for AC meters, but not thermocouple or RTD meters.

or 20000 µV.
For ratiometric readings with bridges, such as load cells, select _Strn under _InPut.
Scaling is normally set up from the front panel using the

How to Maximize Accuracy of Load Cell Measurements
1. Avoid plated connectors or terminal blocks, since dissimilar metals can set up thermoelectric voltages in the millivolt range. If possible, use copper wiring throughout. If you
have to use a junction box, have copper wire touch copper wire.
2. With long cable runs, use six-wire hookup, where the extra two wires are used to sense
the excitation voltage at the load cell. This allows ratiometric meter operation to correct for
voltage drops in the excitation wires.
3. Use twisted, shielded wire from the meter to the load cell to minimize pickup of electrical
noise. Connect the shield to signal input ground at the meter. Do not connect the other
end of the shield.
4. Do not run low-level signals in the same cable tray as electrical power to minimize pickup
of electrical noise carried by power lines.
5. If pickup electrical noise is unavoidable, use the digital filtering capability of our meter to
apply a time constant that averages out random noise over time.
6. Use 5V excitation, not 10V excitation, with miniature or button-type load cells. Even
though small 350-ohm bridge load cells may be rated for 10V, the higher voltage will
produce four times as much self-heating and will cause thermal errors.
7. Operate load cells within their linear range. Do not exceed specified maximum operating
limits so as not to damage the load cell.
8. Operate load cell along their principal axis. Do not apply lateral or twisting forces, as
these will cause deformation and produce non-intended electrical signals.

13. AC TRUE RMS VOLTS & AMPS INPUT
Voltage Ranges
AC voltage or current measurement utilizes the True
RMS signal conditioner board which uses precision
circuitry to compute the root-mean-square of complex
waveforms from 10 Hz to 10 kHz. Accurate measurements are obtained with spikes up to 3 times the
maximum of each range. The input can be AC
coupled to read only the AC component, such as
ripple on a power supply, or DC coupled to read AC
plus DC. The board needs to be configured via
jumpers for the desired voltage or current range, and
for AC or DC coupling. All signal ranges are factory
calibrated with calibration factors stored in EEPROM.
The meter software recognizes the board and will bring up the appropriate menu items for it;
however, it does not recognize the jumper settings. These need to be set manually. Please
see further manual sections for setup of the following features: relay output (16), analog output
(17), and communications (18).

METER SCALING
Refer to the above tables for the full scale counts (or displayed digits) produced by the
available full scale input ranges with a scale factor of 1 and an offset of 0. The decimal point
can be set for direct readout in (milli)volts or (milli)amperes. Decimal point selection does not
affect the counts. For example, a 20V input may be displayed as 20.000V or 20000 mV.
The 5A range, designed for use with a 5A current transformer (CT), is scaled to produce 5000
counts with a scale factor of 1 and an offset of 0. Use with a specific CT will require the scale
factor to be set. For example, for an 800A input, 5A output CT, set a scale factor of 1.6. This is
the desired 8000 count display at 5A divided by the default 5000 count display at 5A. Then set
the decimal point to display to 800.0 at 5A.
All scaling methods applicable to DC, process, strain and load cell meters are available with
AC RMS meters.
INTERNAL SHIELD
To reduce noise pickup inside the meter or transmitter, the
RMS board is fitted with a flexible plug-on shield. If necessary,
This shield may be removed for jumper setting, but must be
reinstalled before closing the instrument.

Shielding for noise reduction
AC RMS measurements are susceptible to signal noise. This is especially true when the instrument has a wide bandwidth. To minimize noise pickup, the input signal wiring should utilize a
shielded twisted pair, and the shield should be connected to signal low at the meter, as
illustrated. If signal low is close to earth ground, such as within 2V, signal low can further be
connected to earth ground at the meter, as illustrated.
PROVISION FOR SIGNAL LEVELS CLOSE TO ZERO
It difficult to obtain meaningful RMS readings of 0 or close to 0 because of electrical noise
pickup. To avoid erroneous very low readings, the RMS board has been programmed to return
0 counts for readings less than 15 counts.
The maximum number of counts is 20000 for the 200.00 mV, 2.0000V, 20.000V, 200.00V,
2.0000 mA, 20.000 mA, and 200.00 mA ranges. The maximum number is 6000 for the 600.0V
range (which is the 2000.0V range for counts purposes), so that 1 count is 0.1V. The maximum
number is 5000 for the 5.000A range (which is the 20.000A for counts purposes), so that 1
count is 1 mA. If needed, the 15-count limit can be changed using the Custom ASCII protocol.

Reading Coordinates of 2 Points Scaling Method
This scaling method applies a straight line fit between two points, which are determined from
actual transducer signals and the desired corresponding meter readings. A low input signal,
such as the output of a pressure transducer at zero pressure, and high input signal, such as
the output of the same transducer at a known high pressure, are applied to the meter. The
desired corresponding low reading and high reading are then entered from the front panel.
The meter then applies straight line fit between the high and low calibration points. This
scaling method has the advantage of calibrating the transducer and meter as a system. The
actual voltages or currents the two points do not need to be known. This method is used with
DC, process and load cell meters when known inputs are available. It is also available for AC
meters. It is not available with thermocouple or RTD meters.

14. THERMOCOUPLE INPUT
PNP transistor
The thermocouple signal conditioner board used for temperature measurement can be configured via jumpers for either type J, K, E, N thermocouples or type T, R, S thermocouples, and
for upscale or downscale open sensor indication. The meter software recognizes the thermocouple board and will bring up the appropriate menu items for it; however, it does not
recognize jumper settings.
For each jumper selection, the thermocouple type, display in °C or °F, and resolution of 1°,
0.1° or 0.01° are user program selectable. High resolution should only be used for relative
readings, not absolute readings. Although available, 0.01° resolution is not recommended for
thermocouples. Offset adjustment is available for thermocouples and is normally set to 0000.0.
If °C is selected, entering an offset of 0273.2 will change the display to Kelvin. If °F is selected,
entering an offset of 0459.7 will change the display to Rankin.
The addition of a relay output board turns the thermocouple meter from a temperature indicator
into an on/off temperature controller. Please see further manual sections for setup of the
following features: relay output (Section 16), analog output (17), and communications (18).

THERMOCOUPLE READING ERRORS
The following types of thermocouple errors need to be combined:
1. Conformity error. The difference between the meter reading and the temperature
stated in NIST Monograph 125 (IPTS-68) for a specified thermocouple type, the thermoelectric voltage in mV, and a cold junction reference temperature of 0°C. For our
meters, this error is typically less than 0.2°C across the entire thermocouple range.
2. Voltage measurement error at 25°C. With our meters, this is less than 0.01% of full
scale at a meter temperature of 25°C, and hence also less than 0.01% of the temperature reading. This error is negligible.
3. Voltage measurement span tempco error. With our meters, this error is less than
±0.003% of the voltage reading/°C as the temperature of the meter changes, and hence
Find Quality Products Online at: sales@GlobalTestSupply.com
also less than ±0.003% of the temperature reading/°C. This error is negligible.

4. Reference junction error.

Temperature
Standard Limit

J
S or R
Our meters do not use an actual cold junction in ice water as
the thermoelectric reference, but they calculate an offset by measuring the voltage drop
across the PN junction of a PNP transistor in close proximity to the junction of the
thermocouple wires and the meter terminals. The voltage drop changes by -2.2 mV/°C.
We specify the reference junction error as 0.5°C for an ambient temperature of 10°C to
40°C.
5. Thermocouple wire errors.
This the largest source of thermocouple reading errors,
and is caused by variations in the alloys found in commercial thermocouple wires. There
are variations from manufacturer to manufacturer, from batch to batch, and within
batches. Shown below are the American Limits of Error ASTM E230-ANSI MC 96.1.
These are the error limits imposed on manufacturers of thermocouple wire, not error
limits applicable to a meter used with ideal thermocouple wire. The “Special Limit of
Error” applies to more expensive “Special Limits of Error” (SLE) thermocouple wire.

The “Limit or Error” tolerance to be used is the listed temperature or percentage,
whichever is greater. Tolerances expressed in °F are 1.8 times those in °C. Percentage
based tolerances are to be computed from temperatures expressed in °C.
Tolerances in the above table apply to new, essentially homogeneous thermocouple
wire, normally 0.25 to 33 mm in diameter (30 to 8 AWG) and used at temperatures not
exceeding the upper temperature limits listed. If used at higher temperatures, these
tolerances do not apply. Thermocouples degrade with time, temperature, and exposure
to the environment.

SIGNAL SHIELDING
200 kΩ ranges and above measurements are susceptible to signal noise. To minimize noise
pickup, the input signal wiring should utilize a shielded twisted pair and the shield should be
connected to signal low and earth ground at the meter, as illustrated. Use 2-wire hookup.

RTD & RESISTANCE CONNECTION
With the appropriate jumper settings, RTD
and resistance measurements allow 2, 3 or 4wire RTD hookup to the J5 connector, as
illustrated. The meter applies a fixed excitation current.
In 4-wire hookup,
lead resistance is not a
factor, since different pairs of wires are used
for excitation and sensing.
In 3-wire hookup,
the meter automatically
compensates for lead resistance by measuring the voltage drop in one current-carrying
lead and assuming that the voltage drop in
the other current-carrying lead is the same.
In 2-wire hookup,
the meter senses the
voltage drop across the load and both lead
wires. The effect of the lead wires can be
measured and subtracted by shorting out the
load during meter setup. The short should be
as close as possible to the load. Ambient
temperature changes will still cause some
error in the readings -- the higher the lead
resistance, the greater the error.
To eliminate lead wire resistance, follow this procedure:
1.
Set the InPut menu item and jumpers for the desired range
2.
Set COnFG to 00011.
3.
Short the two leads at the sensor end.
4.
When the display has settled, push the
key. The meter will then store a value propor-
tional to lead resistance, automatically change COnFG to 00010, and then reset. The same
result is obtained by grounding a Control Input that has been selected for Peak or Valley
(SEtuP 00_0Y, where Y = 1, 2, 4, A, C ).
5.
Remove the short and connect the sensor. The meter now processes the sensor resistance
only.
If the range and associated jumpers are subsequently changed, the above procedure must be
repeated. This procedure is also available through Instrument Setup software, Revision 2.7.0
or later.

RS485 Modbus (with dual RJ45 connectors), USB, USB-to-RS485 converter, Ethernet, and
Ethernet-to-RS485 converter. The dual connectors of RS485 boards are wired in parallel to
allow daisy chaining of addressable meters without use of a hub. Three serial communication
protocols are selectable for all serial boards: Custom ASCII, Modbus RTU, and Modbus ASCII.
may be connected to the meter main board at plug position
A USB-to-RS485 converter board
to be interfaced to a computer and be the device server for a network of up to 31 other meters
on an RS485 bus, while itself retaining all capabilities of a meter. The remote meters need to
be equipped with our RS485 digital interface board with dual 6-pin RJ11 jacks, not our RS485
digital interface with dual 8-pin RJ45 jacks. The dual 6-pin RJ11 jacks on the RS485 board are
wired in parallel to allow multiple meters to be daisy-chained using 6-wire data cables with no
need for hand-wiring or an RS485 hub. The outer two wires are used for ground.
Use 6-wire, straight-through data cables,
all the way from the device server to the last device on the RS485 bus. Connect ATX to ATX,
BTX to BTX, etc., with no crossover as you go from device to device.
To connect a meter with a USB board to a Windows PC,
Type B connectors. Upon first connection, your computer may display “Found new Hardware”
and automatically download and install the required USB driver from the Internet. If installation
is not automatic, download the driver file (with a name like CDM v2.10.00 WHQL Certified.zip)
from
directory as the location of the driver. You will need to use Device Manager (accessible from
Control Panel) to determine the com port. Go down the device list and click on Ports (COM &
LPT) and USB serial port (com #). Note the com port # for use with communications to your
meter, then exit Control Panel. If you later need to change the Com port, right-click on USB
serial port (com #), then on Properties, Port settings, and Advanced. Change port to the
desired number, click OK, then exit Control Panel.

host computer and is used to configure our Ethernet Nodes. It automatically discovers all
Nodes on a LAN or WAN, plus any devices connected to Server Nodes via an RS485 bus. It is
used to configure each Node, such as setting communication parameters, naming the Node
and associated devices, entering email addresses for alarm notification and data requests,
selecting the Node's time zone for time-stamping of emails and streaming data, and upgrading
firmware. Once configuration data has been stored in flash memory of all Nodes, Node

20. INSTRUMENT SETUP VIA PC
Instrument Setup software is a PC program which is much easier to learn than front panel
programming. It is of benefit whether or not the meter is connected to a PC. With the meter
connected to a PC, it allows uploading, editing and downloading of setup data, execution of
commands under computer control, listing, plotting and graphing of data, and computer
prompted calibration. With the meter unconnected to a PC, it provides quick selection of
jumper locations and a printable display of menu selections for front panel setup.
SOFTWARE INSTALLATION
Under Windows 7 or 8, first set User Account Control (UAC) to “Never Notify” so that the
software can write files. Download IS2*.exe onto your PC from our website. Double-click on
the downloaded file to unzip it into a directory, such as c:\temp. Within that directory,
double-click on setup.exe, which will install the software on your PC.
PREREQUISITES FOR CONNECTED USE
1)
PC with an available RS232 or USB port.
2)
Meter to be set up.
3)
RS232 or USB board in the meter. This board
can be removed following meter setup.
4)
RJ11-to-DB9 cable from the meter to a PC
RS232 com port, or a USB cable to a PC USB
port (see Section 1, Ordering Guide).
5)
Instrument Setup software.
ESTABLISHING COMMUNICATIONS
Connect the meter and PC. Apply power to the meter. Be sure that the meter is in Run
Mode, not Setup Mode. To start the software from Windows, click on Start => Programs =>
IS2 => IS2. Click on RS232 => Establish. The program will temporarily set the selected Com
port to the required baud rate, parity, data bits and stop bit. Once communications have
been established, click on Main Menu. The software will sense the type of meter and
installed boards, but it cannot sense jumpers positions nor set jumpers for you. If the
computer is not connected to a meter, select DPM and Series 2.

SETUP OF CONNECTED METER
A setup file can be retrieved from the meter (DPM => Get Setup), be edited (View =>
Setup), be saved to disk (File => Save Setup), be retrieved from disk (File => Open Setup),
and be downloaded into one or multiple meters (DPM => Put Setup). Downloading of setup
files from a PC can be a major time saving when multiple meters have to be set up in the
same way.
You will find that Instrument Setup software is very user friendly, with separate tabselectable windows for Input+Display, Scaling, Filter, Relay Alarms, Communications,
Analog Out, and Lockouts. If the required hardware, such as the analog output board, is not
sensed, the corresponding tab will be grayed out.
ADDITIONAL FEATURES
•
The Commands pull-down menu
allows you to execute certain meter functions by using
your computer mouse. You can reset individual meter functions, display current or peak
readings, and enter numbers to be displayed remotely by the DPM. The first position of a
transmitted number must be a blank, + sign or - sign. Five digits and a decimal point must
be transmitted. Leading 0’s serve as blanks. The Commands pull-down menu will be grayed
out unless a Get Setup has been executed.

the type of board, then prompts you to apply
specific jumpers and calibration signals. Press
Ready to take a reading. Press Repeat to take
more readings. When you have decided on
which reading to accept, press on the number
1 through 10 of that reading. Additional calibration software is available online.
METER SETUP WITH AN UNCONNECTED PC
Instrument Setup software is also of benefit when the
PC is not connected to a meter. Upon launching the
software, click on None for Communications, then on
DPM and Series 2. Click on File => Default Setup to
retrieve a default setup file from disk, or on File => Open
Setup to retrieve a previously saved setup file from disk.
To enter new setup information, click on View => Setup,
then make your screen selections as if you were
connected to a meter. Tabs will be grayed out if you
have not selected the required hardware under the
Input+Display tab. When done, press on Main Menu,
then on View => Menu. The selections made under
Setup will now be shown in the form of the required front
panel programming sequence, where each row corresponds to a menu item selected by the
key, and the seven data columns correspond to values entered via the
and
keys.
Click on any step in the sequence to bring up a detailed help window.
Click on Print for a hardcopy, which you can then use as an instruction sheet to program
your meter via its front panel.
Click on Main Menu => File => Save Setup As to save your setup to disk and have an
electronic record.

21. CUSTOM CURVE LINEARIZATION
Curve.exe is a DOS-based, executable PC program used to set up an Extended meter so that
the readings have a user-defined, non-linear relationship with the input signal. The calculated
linearizing parameters are downloaded into non-volatile memory of the meter. For example, it
allows a meter to correct for transducer nonlinearity or to display volume of an irregularly
shaped tank based on liquid level. The curvefitting algorithm uses quadratic segments of
varying length and curvature, and provides
diagnostics to estimate curve fitting errors.
The program is self-prompting, avoiding the
need for a detailed printed manual. This
manual section is only intended as an introduction and get-started guide.

22. METER CALIBRATION
All analog input and analog output ranges
factory prior to shipment using calibration equipment certified to NIST standards. Calibration
constants are stored digitally in non-volatile memory in EEPROM on the signal conditioner
board and analog output board. This allows the boards to be changed without requiring meter
recalibration. Digital calibration also eliminates much of circuitry that would be associated with
analog calibration, providing superior long term accuracy and stability.
If periodic recalibration is required,

or Ethernet interface board must be installed in the meter for communication to the PC. This
board may be removed following calibration. A certified, calibrated signal source is also
required. The Calibration screen of Instrument Setup Software is accessed by clicking on
Calibration at the top of the DPM Main Menu screen. The PC first recognizes the type of
board, then prompts you to apply specific jumpers and specific known signals for each range.

Adaptive Filter Threshold
Alarm, Latched
Alarm, Non-latched
A threshold which causes an adaptive moving average filter to be reset to the
latest reading when the accumulated difference between individual readings
and the filtered reading exceeds that threshold. Adaptive moving average
filtering allows a meter to respond rapidly to actual changes in signal while
filtering out normal noise. The accumulated difference is also reset to zero
when the latest reading has a different polarity than the filtered reading. A low
adaptive filter threshold is normally selected. A high filter threshold should be
selected if the signal has large transients.
An alarm which stays actuated until reset.
Latched alarms can shut down machinery or
a process when an operating limit has been
exceeded, or maintain an alarm condition
until acknowledged by an operator.
An alarm which changes state automatically
when the reading rises above a specified limit
and changes back automatically when the
reading falls below a limit.
24. GLOSSARY OF TERMS
Autofilter
Auto-tare
Batch Average Filter
Counts
Custom ASCII Protocol
A selectable digital filter mode which automatically selects an appropriate moving average filter time constant from 0.08 sec to 9.6
sec for the encountered noise condition.
A selectable meter operating mode, where
the first reading following power-on or meter
reset is used to zero the display. Further
readings are then relative to this new zero.
A digital filter mode which averages 16 readings and then displays the average.
Readings are taken at 60/sec with 60 Hz power and 50/sec with 50 Hz power.
The reading displayed on the panel meter ignoring the decimal point. One
count = one unit of resolution.
A simplified, short protocol for use with these
panel meters. It allows 31 digital addresses.
Not an industry-standard protocol, like the
more complex Modbus protocol, which is also
offered with the meters.
Deviation Band
Find Quality Products Online at: sales@GlobalTestSupply.com
A band in counts which controls relay action
symmetrically around a setpoint. The relay
- 59 -
www.GlobalTestSupply.com
actuates when the reading falls within the deviation band, and de-actuates
when the reading falls outside. A limit (e.g., 50 counts) is set up around both
sides of the setpoint to create a deviation band (e.g., 100 counts). Setting up a
passband around a setpoint is often used for component testing. Deviation
limits are programmed by entering menu item dEU1b for Alarm 1 and dEU2b
for Alarm 2. The deviation band equals two limits.
Display Blank
A rear panel input which blanks the display when the input is tied to logic
ground by a switch or when 0V is applied (logic level true). The meter display
will light when the input is open or is held at +5V (logic level false).
Extended Meter
A digital panel meter with an enhanced firmware that provides added
capabilities, namely linearization of nonlinear inputs and display of rate of
change from successive readings.
Full Scale
The maximum input signal range for which the meter has been configured. For
example, the most sensitive full scale for the load cell meter is ±20 mV (signal
range from -20 mV to +20 mV).
Function Reset
The action of resetting Peak, Valley, and latched alarms. Takes about 20 msec.
Normally achieved by an external pushbutton switch, which connects a control
input 1 or 2 at the rear of the meter to digital ground. The functions of control
inputs are programmed under Setup. Peak and Valley can also be reset by
simultaneously pressing the RESET and PEAK keys. Latched alarms can also
be reset by simultaneously pressing the RESET and ALARM keys.
Ground Loop
A closed conductive path in external ground wiring that allows stray currents to
flow in ground wiring, creating ground noise. The meters in this manual
minimize ground loop problems by mutually isolating the grounds associated
with meter power, signal input, and all output and communication options.
Jumper
A push-on component which provides a short between two adjacent posts on a
circuit board. Jumpers are used to configure signal conditioner boards for
specific signal types and full scale ranges, and to configure power supply and
communications boards for various modes of operation. Unused jumpers are
stored by pushing one side over an unused post.
Hysteresis, Split
Relay operation is specified symmetrically
around a setpoint. The relay closes (or
opens) when the reading rises above the
setpoint plus one hysteresis limit, and opens
(or closes) when the reading falls below the
setpoint less one hysteresis limit. A narrow
hysteresis band can be used to minimize
relay chatter. A wide hysteresis band can be
used for control.

Hysteresis, Span
Same relay operation as for split hysteresis,
but specified differently. Here the setpoint is
the upper control limit, and the lower control
limit is the setpoint less the hysteresis band.
Menu Mode
Meter Hold
Meter Reset
Modbus
The meter programming mode used for input
and range selection, meter setup, and meter
configuration. Entered into from the Run
mode by pressing the MENU key. The Menu
mode can be locked out completely by a
jumper.
A rear panel input which freezes the meter display and all meter outputs while
that input is tied to logic ground by a switch or is held at 0V (resume operation
when the input is allowed to float or is held at +5V (logic level false).
Causes the meter to reinitialize and take a tare reading when set up for auto-
tare. Takes about 2-3 sec. rESEt is displayed briefly. Achievable by removing
and reapplying power to the meter, by simultaneously pressing the RESET and
MENU keys, by supplying an ASCII command, by stepping through all top-level
menu choices, or by grounding a rear panel control input 1 or 2 if so programmed under Setup.
An industry-standard serial communications protocol which allows devices by
different manufacturers to be digitally addressed by a PC on the same communication line, with up to 247 digital addresses. More complex than the Custom
ASCII protocol, which is also supported by these meters.
Moving Average Filter
A digital filter mode which displays a weighting moving average of readings.
Readings are taken at 60/sec with 60 Hz power and 50/sec with 50 Hz power.
Display update rates remain 3.5/sec with 60 Hz power and 3.0/sec with 50 Hz
power. There are eight moving average modes:
Old average x 1/2 + new reading x 1/2 (equivalent to 0.08 sec RC time constant).
Old average x 3/4 + new reading x 1/4 (equivalent to 0.15 sec RC time constant).
Old average x 7/8 + new reading x 1/8 (equivalent to 0.3 sec RC time constant).
Old average x 15/16 + new reading x 1/16 (equivalent to 0.6 sec RC time constant).
Old average x 31/32 + new reading x 1/32 (equivalent to 1.2 sec RC time constant).
Old average x 63/64 + new reading x 1/64 (equivalent to 2.4 sec RC time constant).
Old avg. x 127/128 + new reading x 1/128 (equivalent to 4.8 sec RC time constant).
Old avg. x 255/256 + new reading x 1/256 (equivalent to 9.6 sec RC time constant).
Offset
A constant adder used for the displayed reading. This is the term b in the
straight line formula y = mx + b, where y is the displayed reading in counts, m
is the scale factor, x is the measured reading in counts, and b is the offset. For
direct readout in (milli)volts or (milli)amps, offset is 0.
Peak Display
The maximum (or most positive) reading since that maximum was last reset.
Reset can be via the meter front panel, an external input, or a software
command. The displayed value can reflect the filtered or unfiltered readings.

Process Signal
A signal whose display requires setup of scale and offset settings for display
in engineering units. A classical process signal is 4-20 mA, where the 4 mA and
20 mA end points can each correspond to a desired meter reading.
Rate of Change Meter
A configuration mode of the Extended meter which allows the display of rate
based on successive readings. The conversion to engineering units is achieved
with the combination of a multiplier from 0.1 to 10,000 and a scale factor.
Reading
The value displayed by the meter. “Taking a reading” is the action of the meter
to make an analog-to-digital conversion. Readings are taken at 60/sec with 60
Hz power or 50/sec with 50 Hz power, and are displayed with an update rate of
3.5/sec with 60 Hz power or 3.0/sec with 50 Hz power.
Remote Display
A display mode which allows the meter to serve as a remote display to another
meter when connected to it by a 4-wire phone cord. Also allows the meter to
transmit raw measurement data to a computer and then display processed data
from the computer. A serial communications option board is required in the
meter. If such a board is not installed or no serial data is received, the meter
displays rESEt.
Reset
RS485 Half Duplex
See “Function Reset” and Meter Reset.”
Serial communications implemented with two wires, allowing data transmission
in both directions, but not simultaneously.
RS485 Full Duplex
Serial communications implemented with four wires, allowing data transmission
in two directions simultaneously.
Run Mode
The normal operating mode of the meter, where readings are taken, as
opposed to the menu mode.
Scale
A constant multiplier used to go from A/D
converter counts to displayed counts. This is
the slope term m in the straight line formula y
= mx + b, where y is the displayed reading in
counts, m is the scale factor, x is the
measured reading in counts, and b is the
offset. For direct readout in (milli)volts or
(milli)amps, scale is 1.
Scaling
The process of setting scale and offset so
that the meter converts analog-to-digital conversion counts to engineering units (such as psi).
Scaling, Coordinates of 2 Points Method
A scaling method where four numbers are entered manually: low input, desired
reading at low input; high input, and desired reading at high input. The meter
then applies a straight line fit. The decimal point is set by the separate dEC.Pt
menu item.

Scaling, Scale and Offset Method
A scaling method where scale and offset are entered manually.
Scaling, Reading Coordinates of 2 Points Method
A scaling method, where the low and high input values are determined from
actual signals. A known low signal is first applied to the meter. That signal is
captured as the low input value, and the desired low reading is entered. A
known high signal is then applied. That signal is captured as the high input
value, and the desired high reading is entered. The meter then applies straight
line fit. This scaling method has the advantage of calibrating the transducer and
meter as a system. The actual voltage or current at either point does not need
to be known. The decimal point is set by the separate dEC.Pt menu item.
Setpoint
Span
Tare
Valley Display
Zero
A value compared to the reading to determine the state of a relay. Term often
used interchangeably with “alarm setpoint.” The relay action can by latching or
non-latching, utilize a hysteresis band, or utilize a deviation band. Hysteresis
bands and deviation bands are specified by two symmetrical limits around the
setpoint.
The number of counts corresponding to a given signal range.
A rear panel input which causes the display to be set to zero when the input is
momentarily tied to logic ground by a switch or is held at 0V (logic level true).
When the input is allowed to float or is held at +5V (logic level false), the meter
displays readings relative to this new zero. A common application is in
weighing, where an external Tare button is pressed to read the weight of an
empty scale (tare), and tare is then automatically subtracted as a constant from
gross weight for display of net weight. Tare can also be used for other applications where a reading relative to starting point is desired.
The minimum (or most negative) reading since that minimum was last reset.
Reset can be via the meter front panel, an external input, or a software
command. The displayed value can reflect the filtered or unfiltered readings.
When used with process meters, zero is an adjustment so that a given low
transducer output reads zero on the meter. Zero is adjusted by programming
offset.
