1, 2, 3 (Alarm 1), and 4 (Alarm 2).

3 SETPTS BUTTON

This button functions only in the run mode. When the
Setpoint/Alarm features are unlocked, pressing this button
sequentially recalls the previous setpoint settings to the display.
After the ‘MIN’ and ‘MAX’ buttons are used to alter those
values as desired, pressing the ‘SETPTS’ button, again, stores
these new values.

Unless the ‘SETPTS’ button is pressed, each of the four setpoint
values is displayed for approximately 10 seconds after the last
press of the ‘SETPTS’ button. Holding the ‘SETPTS’ button
depressed stalls this automatic sequence, retaining the most
recent setpoint number on the display.

ITEM DESCRIPTION

4  /MAX BUTTON

During run mode, pressing this button displays the “HI RDG”
(peak reading) value that has occurred up to the moment the

‘MAX’ button is pressed. This peak reading flashes, to

distinguish its value from the current readings. Since this is a
dynamic peak reading, the value will change if the value
increases while reviewing it.

To return to display of the current readings without resetting the
peak-value memory to zero (0), press the ‘MAX’ button once
again.

To reset the peak-value memory (start a new peak determining
period), press the ‘RESET’ button once.

During the configuration mode, the ‘MAX’ button is used to
change the numerical value of the flashing digit displayed. For
submenu items, such as “L1C.1=0”, pressing the ‘MAX’ button
toggles the choice from “0” to “1”.

The meter allows rapid changes of a displayed numerical value
by making “0” the first value to occur when the ‘MAX’ button is
pressed. After that, the numbers increase to “9” and then roll
over to “0” again. A negative (“–”) symbol may be displayed in
the most significant digit (i.e. the digit at the far left such as
shown here “–.8.8.8.8.8.”)

In the SETPT (SETPOINT) mode (SP1, SP2, etc), pressing the
‘MAX’ button causes the flashing digit to increment by 1 from 0
to 9.

5



/MIN BUTTON

During run mode, pressing the ‘MIN’ button recalls the “LO
RDG” (valley reading) measured since the last press of the
‘RESET’ button. This lowest value flashes, to distinguish it from
the current process display. Since this is a dynamic valley
reading, the value will change if the value decreases while
reviewing it.

ITEM DESCRIPTION

To return to the actual process display, without resetting the low­value memory, press the ‘MIN’ button once again.

To reset the memory for current-value readings (start a new
observation period), press the ‘RESET’ button once and the
meter will return to the run mode.

In the configuration mode, once in a submenu (like input type)
the ‘MIN’ button allows you scroll through the available choices
such as, 0-20 mA or 4-20 mA, etc.

In the SETPT mode, the ‘MIN’ button advances the flashing digit
to the right.

6 MENU BUTTON

In the run mode, this button terminates the measurement
process and allows you to enter the configuration mode,
advancing through the configuration menus.

In the configuration mode, this button will store changes in the
non-volatile memory at the same time advancing the display to
the next menu item.

7 RESET BUTTON

In the run mode, pressing the ‘RESET’ button once erases the
memories of peak (“HI RDG”), valley (“LO RDG”), and ALARM
latches. The display then returns to the run mode.

WARNING: Pressing the ‘RESET’ button two (2) times will
result in a hard reset of the meter. This will clear the Peak &
Valley, Alarm latches and meter reading and immediately begin
a new measurement.

In the configuration mode, pressing the ‘RESET’ button once,
displays the previous selection. For example, if you were in
“IN CNF” then pressed the ‘RESET’ button once, the display will
then show “RD.SC.OF”. Press the ‘RESET’ button two times to
return to the run mode.

5.1 CONDITIONS REQUIRING DISASSEMBLY

You may need to remove the sleeve or open the meter for several reasons:

1. To inspect the rating label on the case (not the same label as on the
sleeve) (Section 5.2.1).

2. To check or change the 115 V ac or 230 V ac or main board jumpers
(Sections 5.2.2 and 5.2.4).

3. To install optional output board(s) (Section 5.2.3).

4. To mount the meter in a panel (Section 5.2.5).

5.2 ASSEMBLY/DISASSEMBLY OPENING

OPENING THE METER

Your meter is fully assembled, but not wired. See Section 7 for wiring
connection for power and sensor inputs. In most cases, if you have ordered
optional boards with the meter, these boards will already be installed.

You will need to remove only the rear cover to complete wiring, but you will
have to open the meter to do one or more of the following:

WARNING!: You must disconnect and turn-off the power and connector
signals before accessing the unit and installing optional boards. Failure to do
so may result in injury!

a. Check or reconfigure the Transformer Jumpers on the Main Board so

that they correspond to your line voltage (W1 and W2 for 115 V ac, or
W3 for 230 V ac). See Section 5.2.2.

b. Install optional boards. See Section 5.2.3.

c. Access jumpers on the Main and optional boards. See Section 5.2.4.

5-1

Setup

Figure 5-1. Meter Exploded View

Using Figures 5-1 as a guide, follow these simple instructions to open the
meter:

IMPORTANT: Turn-off the power and input signals from the unit before
proceeding. Failure to do so may result in injury!

1. Remove the cover mounting screw that secures the rear protective cover
to the meter, and remove the Rear Protective Cover.

If you are simply wiring the meter–but not checking jumpers or installing
or removing boards–this is as far as the meter needs to be
disassembled. Go to Section 5.2.1.

2. Remove all wiring connectors from the rear of the meter.

3. Remove the two thumbnuts that secure the case to the sleeve.

4. Remove the sleeve completely by sliding it back from the front bezel.

To look at the Rating/Product ID label on the case, you must follow the first
step as described in Section 5-2. Refer to Figure 5-2 for the location of the
Product Identification label.

The meter is protected in accordance with Class I of EN61010. Refer to
Safety Considerations page.

WARNING: If your meter is to be wired to sensors to control inputs that
could be hazardous potentials, these potentials will be carried to the 20-pin
output connector (P2) at the rear. They will also be present on the meter’s
circuit boards. Follow all instructions carefully BEFORE connecting the
meter to any source of power.

DO NOT contact any exposed metal parts, install optional board(s), change
jumpers, or in any way disassemble or assemble the meter while it is
connected to AC voltage.

Note the following information and guidelines for safe operation of your
meter:

Power Voltage

Your power source voltage rating should agree with the voltage under which
the meter has been configured to operate. The first thing you should do is
verify this.

The meter’s operating voltage is shown in the VOLTS: entry of the Product
Identification and Serial Number Label. It is located on the case, as shown in
Figure 5-2, and is clearly visible on the meter packing box.

5.2.2 Main Board Power Jumpers

To check voltage jumpers or to change from 115 V ac to 230 V ac:

CAUTION: The meter has no power-on switch; it will be in operation as soon
as you apply power. To change the factory preset jumpers, disconnect the
power from the unit. Failure to do so may result in injury! The jumpers must
be changed by specifically trained personnel.

1. “Reveal the Main Board” (refer to Section 5.2, Disassembly).

2. Locate the main board assembly and position it in front of you the same
way as shown in Figure 5-3.

3. On the main board, locate the transformer jumpers W1, W2, and W3
near the transformer T1.
If your power requirement is 115 V ac, jumpers W1 and W2 should be
installed. (DO NOT INSTALL W3)

5.2.5 PANEL-MOUNT ASSEMBLY

The meter can be mounted in a panel so that the front of the meter is flush
with the vertical panel surface. Panel mounting can be seen as simply
“sandwiching” the panel between the inner case and the outer sleeve in the
last phases of assembly. Figure 5-14 shows the panel cutout dimensions,
and the dimensions for the panel thickness. It requires that the following
already be done:

1. Your line voltage rating has been checked against the meter rating on
the Product ID and serial number label on the meter case. See Section

5.2.1.

2. You have configured all jumpers–those on the main board as well as
those on any optional boards. See Section 5.2.2 for main board jumper
configuration and the appropriate sections for optional board jumper
configuration.

3. You have installed all optional boards and inserted the main board
assembly back into the case. See Section 5.2.3.

4. You have wired P1, the AC power connector, and P2 the input output
control connector; connectors are not installed in the meter, but are
ready to be installed. See Section 7.

5. You have wired all connectors for optional boards; connectors are not
connected to the meter, but are ready to be installed.

If all of these steps are done, use Figure 5-14 as a guide:

CAUTION: Connectors with the wiring connections will be installed after
mounting the unit.

11. Set P1, the AC power connector, aside and connect or reconnect all
other connectors to the back of the meter using Figures 4-3 and 4-4 in
Section 4.2 as guides.

Connect P1 last.

NOTE: The P1 connector is “keyed”; it is shaped in such a way that it fits
only the J1 male pins.

12. Replace the rear protective cover and secure it with the cover mounting
screw.

Your meter is now ready for operation and you can turn-on the power.

The meter display should light, and pass through “RESET 2” to run or
display mode. If the meter flashes an overscale or overload message, press
the ‘MENU’ button to advance to the configuration mode. Do not be
concerned about overloads (the +S input can stand 120 V continuously and
current inputs can handle ten times rated current).

Jumper Positions

6-1

6.1 INTRODUCTION

This section is for the configuration and setup of your jumper positions for
readrate, unipolar or bipolar signal input, sensor input signal jumpers, sensor
excitation jumpers, pushbutton lockouts and lockout of lockout configuration
menus.

6.2 S1 JUMPER POSITIONS FOR READRATE AND UNIPOLAR OR
BIPOLAR INPUT(S)

The typical readrate for your meter is 3/per second. This requires that no
jumper has been installed in the S1A position and Input Configuration
(“IN CNF”) bit “INP.2” has been set to equal “0”. Your meter is capable of a
fast readrate of 13/per second. This requires that you install a jumper in the
S1A position and the Input Configuration (“IN CNF”) bit “INP.2” has been set
to equal “1”. Refer to Figure 6-1 for the location of the S1 jumpers.

The typical setting for your meter is unipolar. For unipolar input, no jumper is
installed in the S1B position and Input Configuration (“IN CNF”) bit “INP.3”
must be set to equal “0”. For bipolar inputs, install a jumper in S1B and set
Input Configuration (“IN CNF”) bit “INP.3” to equal “1”.

6.3 S2 JUMPER POSITIONS FOR INPUT RANGES

The following are the input signal jumper positions required to be installed in
the “S2” position on your meter for the CURRENT or VOLTAGE input ranges
you require. These jumper positions include those that are required for
sensor excitation. Jumpers S2-N & S2-T are for either 1.5 to 11 Vdc or
24 Vdc sensor excitation. To select desired excitation see Section 6.4. Refer
to Figure 6-1 for the location of the S2 jumpers.

8. Methods for Scaling the Meter to
Display in Engineering Units

8.1 INTRODUCTION

This section is for scaling the meter to read in desired engineering
units. This meter is capable of producing any engineering units up
to 6 digits regardless of decimal point. Even though this is a strain
gauge input meter it is capable of working with high voltage, current
and potentiometric inputs. The difference between strain gauge
input and a voltage input is ratiometric versus non-ratiometric
inputs. A strain gauge based sensor is ratiometric which means its
output is directly proportional to the supply voltage powering it.
Most millivolt sensors are ratiometric (strain gauge input)

The decimal point is completely programmable.

Performing the following steps will ensure that the meter is prop­erly scaled.

1. Make sure that all jumpers are in their correct location(s). (Refer
to Section 6)

2. Provide AC power to the instrument (Refer to Section 7.3)

3. Check with a multimeter that the proper sensor excitation exists.

4. Wire the sensor to the meter (Refer to Section 7.2)

5. Program the unit for the desired display with strain gauge inputs
(Bridge inputs, refer to Section 8.2), Voltage inputs (Refer to
Section 8.3), Current inputs (Refer to section 8.4), or Potenti­ometer inputs (Refer to Section 8.5).

8.2 STRAIN GAUGE (BRIDGE) INPUT, PROGRAMMING THE
METER FOR A DESIRED DISPLAY

An easy way to program your unit is to follow the example and step
by step procedure below and just modify it for your exact require­ments.

8

Scaling to
Display
Engineering
Units

EXAMPLE: An end user wants to scale the meter for a 200 PSI,
0-100 mV voltage output, pressure transducer. You want the meter
to display in hundreds of a PSI from 0 to 200.0 PSI. The pressure
sensor requires 10 Vdc excitation power.

8-1

The two most common methods of scaling, Method I scaling
without simulating a known load, and Method II scaling by simu­lating known loads will be demonstrated. Sometimes end users
simulate known voltages instead of known physical standards
(pressures); this is covered in Method II. A third method is for a
unique case where you are scaling with a known load and you want
the display to have 3 or more decimal places. Method III is a little
complicated and should only be used, if you are looking for really
accurate results and you desire a display with 3 or more places to
the right of the decimal point.

A. Set the correct jumpers on the meter. (Refer to Section 6).

Install jumpers S3A & S3C and S4A & S4C on the main board.
Installing jumpers S4A and S4C will provide a factory set 10 Vdc.
Adjusting R38 will vary the excitation. Use a multimeter while
adjusting R38.

position(“0”). Refer to Section 9.1 for information on lockout
bytes.

If the unit has been programmed previously make sure that at least
the following lockout bytes are unlocked. If they are Not unlocked
you will not be able to scale the meter.

MENU SUBMENU

Scroll to the menu by pressing the ‘MENU’ button. Enter a
submenu by pressing the ‘MIN’ button. select “0” or “1” by pressing
the ‘MAX’ button. Always press the ‘MENU’ button when leaving
a submenu to store the values you entered.

METHOD I: SCALING WITHOUT SIMULATING A KNOWN LOAD.

NOTE: All of the following steps are accomplished by using the
front panel buttons.

1. Scale the instrument by entering only 3 parameters.

The 3 parameters are “RDG SC” (Reading Scale), “RDG OF”
(Reading Offset), and “DEC PT” (Decimal Point).
Calculate “RDG SC” using the following formula:

8-4

RDG SC= display span/((sensor’s mV/Voutput) (natural gain))
RDG SC= 200/(10 x 10000) = 0.002
Where: display span= 200 – 0 = 200
Sensor’s output = 100 mV/10V EXC =10 mV/V
Meter’s natural gain= 10000 (Obtained from Table 8-1)

Pressing the ‘MENU’ button will take you through all the different
menus listed below. When you wish to enter a menu, to the
submenu 1 stage, press the ‘MIN’ button. To make a selection, in
submenu 1, press the ‘MAX’ button. If the submenu has more than
one item to select use the ‘MIN’ button to scroll to the next item of
choice and again use the ‘MAX’ button to make your selection.

After making all your choices, in submenu 1, enter these selections
by pressing the ‘MENU’ button which will momentarily flash
“STORED” on the display. If the item selected in submenu 1 has a
submenu 2 associated with it, press the ‘MIN’ button to go to
submenu 2. Select your choice by pressing the ‘MAX’ button and
enter your choice by pressing the ‘MENU’ button. Pressing the
‘RESET’ button one time brings you back one ‘MENU’ item,
pressing it a second time returns you to the run mode.

2. Now you are in the run mode and the transducer is connected to
the meter. Simulate two loads on the transducer and record the
meter display as “INPUT1” and “INPUT2” and record what
each of these readings (“READ 1” and “READ 2”) should display
on a piece of scrap paper or in the space provided below. These
numbers will be the INPUT values entered in the “IN.SC.OF”
scaling. Normally the two points that are calibrated are the no
load condition and 3/4 full scale. However, you may use any two
measurements.

“INPUT1” “INPUT2”

“READ 1” “READ 2”

Assume that you simulate no load and the display indicates “13”,
and when you simulate 160 PSI the display indicates “80567”.

The following data will now be entered into the 2-point scaling
“IN.SC.OF” method.

“INPUT1”: 13 “READ 1”: 000000

2. Now you are in the run mode and the load cell is connected to
the meter. Simulate two loads on the transducer and record the
meters display as “INPUT1” and “INPUT2” and record what
each of these readings (“READ 1” and “READ 2”) should display
in the spaces provided below. These numbers will be the INPUT
values entered in the “IN.SC.OF” scaling. Normally the two
points that are calibrated are the no load condition and 3/4 full
scale. However, you may use any two measurements.

“INPUT1” “INPUT2”

“READ 1” “READ 2”

Assume that you simulate no load the display indicates “–55.6”,
and when you simulate 4.0000 pounds the display indicates
“16136.6”.

8-12

The following data will now be entered into the 2-point scaling
“IN.SC.OF” method.

“INPUT1”: –55.6 “READ 1”: 00000.0
“INPUT2”: 16136.6 “READ 2”: 04000.0

Ignore the decimal point position for the read values. Just note how
many zero’s (or places to the right of the decimal) you need.

In this example there were 4 decimal places needed and there are 4
zeros after the “4” in the READ 2 value (ignore the decimal point).

You must alter the “RDG SC” factor as follows. Note that the
decimal point above in the “READ 1” and “READ 2” values is not
in the correct position. You need to move it 3 places to the left to
make it correct.

By looking at Table 8-2 below, you can see that a value of 0.00100
must be entered for a new “RDG SC” value.

8.3 VOLTAGE INPUT (NON RATIOMETRIC),
PROGRAMMING THE METER FOR A DESIRED DISPLAY

An easy way to program your unit is to follow the example and step
by step procedure below and just modify it for your exact require­ments.

EXAMPLE: An end user wants to scale the meter for a 4000 PSI,
1-5 Vdc voltage output, pressure transducer. You want the meter to
display in tenths of a PSI from 0 to 4000.0 PSI. The pressure sensor
requires 12-30 Vdc excitation power.

The two most common methods of scaling, Method I scaling
without simulating a known load, and Method II scaling by simu­lating known loads will be demonstrated. Sometimes end users
simulate known voltages instead of known physical standards
(pressures); this is covered in Method II. A third method is for a
unique case where you are scaling with a known load and you want
the display to have 3 or more decimal places. Method III is a little
complicated and should only be used, if you are looking for really
accurate results and you desire a display with 3 or more places to
the right of the decimal point.

A. Set the correct jumpers on the meter. (Refer to Section 6)

8.4 CURRENT INPUT, PROGRAMMING THE METER FOR A
DESIRED DISPLAY

An easy way to program your unit is to follow the example and step by
step procedure below and just modify it for your exact requirements.

EXAMPLE: An end user wants to scale the meter for a 5000 PSI,
4-20 mA current output, pressure transmitter. He wants the meter
to display in tenths of a PSI from 0 to 5000.0 PSI. The pressure
sensor requires 12-30 Vdc excitation power.

The two most common methods of scaling, Method I scaling without
simulating a known load, and Method II scaling by simulating known
loads will be demonstrated. Sometimes end users simulate known
currents instead of known physical standards (pressures), which is
covered in Method II. A third method, Method III, is for a unique
case where you are scaling with a known load and you want the
display to have 3 or more decimal places. Method III is a little
complicated and should only be used, if you are looking for really
accurate results and you desire a display with 3 or more places to the
right of the decimal point.

All of the following steps are accomplished by using the front panel
buttons.

1. Scale the instrument by entering only 3 parameters. The 3
parameters are “RDG SC” (Reading Scale), “RDG OF” (Reading
Offset), and “DEC PT” (Decimal Point).

Calculate your “RDG SC” (Reading Scale) using the following
formula:

RDG SC= display span/ ((sensors span normally 16 mA) (5000))

RDG SC= 5000/(16 x 5000) = 0.06250
Where: display span= 5000 – 0 = 5000
Sensor’s output span= 20 mA – 4 mA = 16 mA

Pressing the ‘MENU’ button will take you through all the different
menus listed below. When you wish to enter a menu, to the
submenu 1 stage, press the ‘MIN’ button. To make a selection, in
submenu 1, press the ‘MAX’ button. If the submenu has more than
one item to select use the ‘MIN’ button to scroll to the next item of
choice and again use the ‘MAX’ button to make your selection.

After making all your choices, in submenu 1, enter these selections
by pressing the ‘MENU’ button which will momentarily flash

If the item selected in submenu 1 has a submenu 2 associated with
it, press the ‘MIN’ button to go to submenu 2. Select your choice
by pressing the ‘MAX’ button and enter your choice by pressing
the ‘MENU’ button.

Pressing the ‘RESET’ button one time brings you back one
‘MENU’ item, pressing the ‘RESET’ button two times returns you

Ignore the decimal point position for the READ values. Just note
how many zero’s (or places to the right of the decimal) you need.

In this example there were 4 decimal places needed and there are
4 zeros after the “2” (in the “READ 2” value).

You must alter the “RDG SC” factor as follows. Note that the
decimal point above in the “READ 1” and “READ 2” values is not
in the correct position. You need to move it 3 places to the left to
make it correct.

8.5 POTENTIOMETER, PROGRAMMING THE METER FOR
A DESIRED DISPLAY

An easy way to program your unit is to follow the example and
step by step procedure below and just modify it for your exact
requirements.

EXAMPLE: An end user wants to scale the meter for a 200 PSI,
0-500 ohms output, pressure transducer. You want the meter to
display in hundredths of a PSI from 0 to 200.00 PSI. The pressure
sensor requires 10 Vdc excitation power.

The two most common methods of scaling, Method I scaling
without simulating a known load, and Method II scaling by simu­lating known loads will be demonstrated. Sometimes end users
simulate known voltages instead of known physical standards
(pressures); this is covered in Method II. A third method is for a
unique case where you are scaling with a known load and you want
the display to have 3 or more decimal places. Method III is a little
complicated and should only be used, if you are looking for really
accurate results and you desire a display with 3 or more places to
the right of the decimal point.

8-40

A. Set the correct jumpers on the meter as shown in Figure 8-10.
(Refer to Section 6 for additional information)

Configure jumpers on S1 and S2 as shown in Section 6.

Install jumpers S3A & S3C and S4A & S4C on the main board.
S4A & S4C will provide a factory set 10 Vdc. Adjusting R38 will
vary excitation. Use a multimeter when adjusting R38.

METHOD I: SCALING WITHOUT SIMULATING A KNOWN LOAD.

All of the following steps are accomplished by using the front panel
buttons.

1. Scale the instrument by entering only 3 parameters. The 3
parameters are “RDG SC” (Reading Scale), “RDG OF” (Reading
Offset), and “DEC PT” (Decimal Point).

Calculate “RDG SC” using the following formula:

RDG SC= display span/((sensor’s output span) (natural gain))

RDG SC= 200/(10 x 10000) = 0.002
Where: display span= 200 – 0 = 200
Sensor’s output span= 10 volts
Meter’s natural gain= 10000 (from Table 8-5)

MIN/MAX/MENU These are the buttons on the meter you are to

press to access the parameters given in the
same column.

MAIN MENU/ These are headings for the table columns.
SUBMENU:

DISPLAYED These are parameters seen on the display
INFORMATION: after pressing either ‘MIN’, ‘MAX’, or ‘MENU’

button(s).

NOTE: If you press the ‘RESET’ button two times while the meter is in the
run mode, all Setpoints, Alarms, Peak & Valley will be reset and the meter
will begin new measurements.

If you press the ‘RESET’ button one time while in the configuration mode,
you will move one MAIN MENU backwards and any selection will not be
saved. If you press the ‘RESET’ button two times while in the configuration
mode, you will reset the meter and only those menu items saved by pressing
the ‘MENU’ button will be saved.

9.1 Individual Lockout Information

To restrict access to different parameters of the program in the meter, you
may want to lockout parts of the meter. When you lock out a parameter, it
will no longer appear when you scroll through the menu. To lock out specific
parameters of the meter (setpoint, scaling), refer to the following tables.

Once set (to unlock useful features for a given application and to lock out
any features), these four “L1C”, “L2C”, “L3C”, and “L4C” can be rapidly
skipped over by pressing the ‘MENU’ button four times.
