4.0 PARTS OF THE METER
4.1 Front Of The Meter
The following is a brief description of each part of the front of the meter.
ITEM DESCRIPTION
.8.8.8.8.8. or 8.8.8.8.8.8.
1
6-digit, 14 segment, alphanumeric 0.54" high
LED display with programmable decimal point.
SETPOINT LED
2
These LEDs, labeled 1 through 4, display the status of setpoints 1, 2, 3 (Alarm 1), and 4 (Alarm 2).
SETPTS BUTTON
3
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.
Figure 4-1. Front Detail
CF 67 4 M1291/N/0403 11279ML-02 Rev. A
S /MAX BUTTON
4
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.
X /MIN BUTTON
5
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.
To return to the actual process display, without resetting the low-value 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.
MENU BUTTON
6
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.
RESET BUTTON
7
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).
CF 67 7 M1291/N/0403 11279ML-02 Rev. A
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 t115 V ac, or W3 for 230 V ac). See Section 5.2.2
b. Install optional boards.
c. Access jumpers on the main and optional boards. See Section 5.2.4
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 form the front bezel.
5. Using Figure 5-2 as a guide, bend the side-panel detents on the case outward and pull the board assembly out
of the case by the mounting screw stem.
NOTE: From this point forward, these 5 steps are referred to as “Reveal the main board”.

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 presser jumper, disconnect the power from the init. 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). If your power
requirement is 230 V ac, jumper W3 should be installed. (DO NOT INSTALL W1 OR W2)

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.
CF 67 13 M1291/N/0403 11279ML-02 Rev. A
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.
Figure 5-14. Panel Mounting Assembly
6. Punch or cut a hole in the panel using the panel cutout dimensions in Figure 5-14. Remove burrs and paint the
panel as required
7. Insert the panel-mount gasket around the rear of the case and slide it forward to the bezel (if it’s not already in
place).
8. Working from the front of the panel, insert the case assembly, rear end first, all the way into the panel cutout
such that the gasket firmly backs the panel surface.
9. Working from the rear of the panel, slide the sleeve forward over the case and up to the panel surface. The
panel should now be sandwiched between the bezel-backed gasket in front and the sleeve in back.
10. Replace the thumbnuts that secure the sleeve tabs to the case.
WARNING: Do not “turn-on” the ac power and input signals until all connections are connected to the meter.
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.
Your meter is now ready for operation and you can turn-on the power.
CF 67 14 M1291/N/0403 11279ML-02 Rev. A
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).
6.0 JUMPER POSITIONS
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 S2B 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.
