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”.

Figure 5-2. Board Assembly Removing/Installing Detail

The meter is now disassembled to the point where you can check and configure jumpers and install boards.

Reinserting the Main Board Assembly into the Case

Reinsert the main board into the case once jumper s and optional boards have been configured and installed.

Spread the side-panel detents of the case and carefully slide the main board all the way in.

5.2.1 Safety Precaution/Product Id Label

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 options 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 VOLTS: entry of the Product Identification and Serial Number label. It is

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 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.

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.

You are now ready to proceed with scaling your meter to display in engineering units as described in Section 8.

8.0 METHODS FOR SCALING THE METER TO DISPLAY IN ENGINEERING UNITS

8.1 Introduction

There are two basic methods for scaling your meter to display engineering units; scaling by using measured input
values or scaling without connecting a sensor using assumed input values. Both methods use the Input Scale and
Offset (“IN.SC.OF”) method.

8.2 Setup Meter Input Type and Range

If you have received your meter setup for your required input and do not require changes or rescaling, skip this
section entirely and proceed with the normal use of your meter.

If you received your meter and you only require a scaling change, proceed with the steps in Section 8.2.2.

CF 67 21 M1291/N/0403 11279ML-02 Rev. A

If you received your meter and it is has been configured for an input other than what you require, you must proceed
with the following steps before rescaling the display:

WARNING: You must set your jumper positions at the S1 and S2 positions BEFORE proceeding. Refer to Section
6 for jumper positions.

and then will display

8.3 Scaling Your Meter Using 2-Coordinate Input Scale And Offset (IN.SC.OF) With Sensor Connected To Your Meter

The most accurate method for scaling your meter to display engineering units is by connecting your sensor to your
meter, apply two known loads, record them as INPUT1 and INPUT2 respectively and use these numbers for entry
into 2-coordinate Input Scale and Offset (“IN.SC.OF”).

The typical factory calibration and configuration is for the meter to accept a 0-100 mVdc input signal and scaled to
display 0 to 100000.

An example would be a 4-wire pressure transducer or load cell that sends an output signal of 0-100 mVdc. With a
signal input of “0 mVdc”, the display will show “000000”and when a signal input of 100 mVdc is applied, the meter
will display “100000”.

NOTE: Your display may not show exactly “000000” and may display a negative number such as “–000015” or a
positive number such as “000023”.

Using Input Scale and Offset (“IN.SC.OF”) allows you to accurately scale your input signal to display in any
engineering units you require.

NOTE: Although the full span input of your sensor signal is preferred for maximum resolution, you may record any
two points within the signal span for scaling accurately into engineering units.

The following will walk you step by step in configuring your meter for scaling your meter using the Input Scale and
Offset (“IN.SC.OF”) procedure.

“IN.SC.OF”.

8.3.2 Scaling Your Meter With Your Sensor Connected

Before proceeding, you must first apply a low input (“INPUT 1”) and a high input (“INPUT 2”) into your meter and
record the exact display shown. As explained in Section 8.3, the display you will be recording will be 0 and 100000
if your meter has not been changed from the typical factory setup and calibration. The following is an example
using the numbers below as the recorded input displayed on the meter. You should use the numbers you have
recorded:

Low input: 0 mVdc
Meter display (“INPUT 1”): 000000
High input: 100 mVdc
Meter display (“INPUT 2”): 100000

NOTE: If you are using an input signal that is reverse acting (e.g. 100-0 mVdc), then the 100 mV reading would be
“INPUT 1” and the 0 mV reading would be “INPUT 2”.

In addition to recording your display readings for your two inputs, you must also decide what you want these inputs
to display on your meter.

In order to simplify this (especially if you want to display numbers to the right of the decimal point position), you
should think of your meter as a process indicator and your decimal point as being passive or cosmetic.

As an example, if you wanted your display to read 0.000 to 68.000, you would record and enter your “READ 1”
number as 000000. and your “READ 2” number as 068000. Then after storing these numbers, you would then
place your decimal point position (refer to Section 8.3.4) so that your display would show 0.000 to 68.000.

CF 67 23 M1291/N/0403 11279ML-02 Rev. A

Record your “INPUT1” and “READ 1” numbers, and your “INPUT2” and “READ 2” numbers, record them below and
proceed as follows:

Example
INPUT1= 000003.
READ 1 = 000000.
INPUT2 = 100018.
READ 2 = 068000.

Measured Value

Press the ‘RESET’ button two times. The display will

currently measured values.
Your meter is now calibrated. If you need to offset your zero reading on your meter after calibration, you must
proceed with the following steps:

8.3.4 Entering Zero Offset Numbers

You have two (2) ways to enter a zero offset. The first and easiest is using the TARE function. This is accomplished
by connecting a momentary contact to the rear P2 connector at P2-1 and P2-4. Each time this momentary contact
is activated, the display will automatically display zero.

The second method for entering a zero offset number is Reading Offset (“RDG OF”).

The RDG OF (Reading Offset) menu item should be used if the meter shows a nonzero reading with zero input.
The offset value zeroes the display by canceling out the nonzero reading.

If your meter displays a positive reading at zero input, you must enter a negative offset value. If your meter displays
a negative reading at zero input, you must enter a positive offset value.

If you are using an active decimal point (RDG.2=0), your offset value will be the negative of the display reading at
zero point.

If you are using the more common independent decimal point (the factory setting, RDG.2=1), follow these
instructions to convert the display reading to the appropriate offset value:

1. Note the display reading at zero input, ignoring the decimal point. This reading represents the count value - the

number of whole counts that need to be offset.

2. Shift the count value to the left side of the decimal point.

3. If the count value is positive, make it negative by replacing the leading digit (the left-most digit) with a minus

sign. If the count value is negative, make it positive by replacing the negative sign with a zero.

Example 1: Your meter displays 000.003 when the input is zero. The count value is 000003. Shift this value to the
left side of the decimal point: 003.000. Change the leading zero to a minus sign: -03.000. This is the “converted
offset value” you will use for configuring RDG OF.

Example 2: Your meter displays -00.003 when the input is zero. The count value is -00003. Shift this value to the
left side of the decimal point: -03.000. Change the leading minus sign to a zero: 003.000. This is the “converted
offset value” you will use for configuring RDG OF.

If the nonzero reading is fluctuating between two numbers, convert the smaller count value to the offset value, then
add a 5 just right of the decimal point. This adds half a count to the offset. For example, the display is fluctuating
between 00.0001 and 00.0002. Calculate the offset using the 000001 count value. The converted offset value is -

1.0000. Add a 5 to the right of the decimal point: the final offset value is -1.5000.

‘RESET’ ‘RESET’ “RESET2”

then The
Measured
Value

NOTE: If after zeroing the display with RDF OF, the reading again drifts from zero, the required offset value is the
sum of the current RDG OF value and the current converted offset value. The examples below illustrate the

calculation of required offset values when using an independent decimal. If you are using an active decimal point,
the current converted offset value is simply the negative value of the display reading.

Example 1: You use a RDG OF value of –1.0000 to zero the meter. The next morning, the meter displays 00.0008
at zero input; you need to rezero. The current count value is 000008; shifting this value to the left of the decimal
makes it 08.0000, and making the value negative makes it –8.0000. The required RDG OF value is the sum of the
current RDG OF value (–1.0000) and the current converted offset value (–8.0000):

–1.0000 + –8.0000 = –9.0000

Example: You use a RDG OF value of –1.0000 to zero the meter. The next morning, the meter displays –0.0008 at
zero input; you need to rezero. The current count value is –00008; shifting this value to the left of the decimal
makes it –8.0000, and making the value positive makes it 08.0000. The required RDG OF value is sum of the
current RDG OF value (–1.0000) and the current converted offset value (08.0000):

–1.0000 + 08.0000 = 07.0000

If you require further configuration(s) for your specific application, refer to Sections 9 through 21.

8.4 Scaling Your Meter Without Connecting A Sensor Using Calculated Values

Your meter can be scaled without connecting a sensor and taking measured values using Input Scale and Offset
(“IN.SC.OF”).

The typical configuration and scaling of your meter is a 0-100 mVdc input with a display equal to 0 to 100000. If
your meter has not been rescaled and your input is 4-20 mAdc, you can use the factory scaling “0” as your
“INPUT1” and “100000” as your “INPUT2” and proceed with the step-by-step procedure in Section 8.4.1.

If you need to change your input signal, you must rescale your meter as described in the following steps:

8.4.1 Preparing Your Meter For Scaling With Input Scale And Offset

If you are changing your input signal you must follow the instructions for installing the correct jumper positions as
described in Section 6 and the sensor connections as described in Section 7.

WARNING: Do not connect your AC meter power until all input jumpers and sensor input connections are
completed. Failure to do so could result in damage to your sensor and/or the meter.

The following procedure will direct you step by step in preparing your meter for rescaling using Input Scale and
Offset (“IN.SC.OF”).

NOTE: The following procedure will scale your meter to display in microvolts and insure that your final scaling is as
accurate as possible.

You may need to enter a zero offset after scaling your meter. There are two (2) ways to enter a zero offset. The
first and easiest is using the TARE function. This is accomplished by connecting a momentary contact to the rear
P2 connector at P2-1 and P2-4. Each time this momentary contact is activated, the display will automatically
display zero.

8.4.4 Entering Zero Offset Numbers

The RDG OF (Reading Offset) menu item should be used if the meter shows a nonzero reading with zero input.
The offset value zeroes the display by canceling out the nonzero reading.

If your meter displays a positive reading at zero input, you must enter a negative offset value. If your meter displays
a negative reading at zero input, you must enter a positive offset value.

If you are using an active decimal point (RDG.2=0), your offset value will be the negative of the display reading at
zero point.

If you are using the more common independent decimal point (the factory setting, RDG.2=1), follow these
instructions to convert the display reading to the appropriate offset value:

1. Note the display reading at zero input, ignoring the decimal point. This reading represents the count value - the

number of whole counts that need to be offset.

2. Shift the count value to the left side of the decimal point.

3. If the count value is positive, make it negative by replacing the leading digit (the left-most digit) with a minus

sign. If the count value is negative, make it positive by replacing the negative sign with a zero.

Example 1: Your meter displays 000.003 when the input is zero. The count value is 000003. Shift this value to the
left side of the decimal point: 003.000. Change the leading zero to a minus sign:
–03.000. This is the “converted offset value” you will use for configuring RDF OF.

Example 2: Your meter displays –00.003 when the input is zero. The count value is –00003. Shift this value to the
left side of the decimal point: –03.000. Change the leading minus sign to a zero: 003.000. This is the “converted
offset value” you will use for configuring RDG OF.

If the nonzero reading is fluctuating between two numbers, convert the smaller count value to the offset value, then
add a 5 just right of the decimal point. This adds half a count to the offset.

For example, the display is fluctuating between 00.0001 and 00.0002. Calculate the offset using the 000001 count
value. The converted offset value is -1.0000. Add a 5 to the right of the decimal point: the final offset value is -

1.5000.

‘RESET’ ‘RESET’ “RESET2” then

the Measured
Value

NOTE: If after zeroing the display with RDF OF, the reading again drifts from zero, the required offset value is the
sum of the current RDG OF value and the current converted offset value. The examples below illustrate the

calculation of required offset values when using an independent decimal. If you are using an active decimal point,
the current converted offset value is simply the negative value of the display reading.

Example 1: You use a RDG OF value of -1.0000 to zero the meter.
The next morning, the meter displays 00.0008 at zero input; you need to rezero. The current count value is 000008;
shifting this value to the left of the decimal makes it 08.0000, and making the value negative makes it -8.0000. The
required RDG OF value is the sum of the current RDG OF value (-1.0000) and the current converted offset value (-

8.0000):

-1.0000 + -8.0000 = -9.0000

Example 2: You use a RDG OF value of -1.0000 to zero the meter.
The next morning, the meter displays -0.0008 at zero input; you need to rezero. The current count value is -00008;
shifting this value to the left of the decimal makes it -8.0000, and making the value positive makes it 08.0000. The
required RDG OF value is sum of the current RDG OF value (-1.0000) and the current converted offset value
(08.0000):

-1.0000 + 08.0000 = 07.0000

• display brightness [RDG.3]

• leading zero suppression on your meter display [RDG.4]

Direct scale and Offset: these two values are used in the straight line equation, y = mx + b. (RD.SC.OF)

Display = m times input plus b or [ m (input) + b ] (where m is the RDG SC and b is the RDG OF).

The 2-data-point method allows the user to use two known points to convert from one scale to another. For
example, to convert from degrees Fahrenheit to degrees Celsius, enter two (2) known points, such as 32°F = 0°C
and 0F = 17.77°C. The meter will automatically compute scale and offset and display the correct value.

9.2.3 RDG SC (Reading Scale) AND RDG OF (Reading Offset)

Typically, this would be used only when you cannot connect a known load to your meter, you require a display with
3 or more positions to the right of the decimal point position, you have scaled your meter using Input Scale and
Offset (“IN.SC.OF”) and want to enter a constant multiplying factor, or you have an extremely large offset.

If “RDG.1=0” were chosen, then you go automatically into “RDG SC” and “RDG OF” where:
“RDG SC” is reading scale from -99999 to +499999 where you set the display to “1.00000” and “RDG OF” is
reading offset from -99999 to 999999 when you set the display to “000000”.
When “RDG SC” is displayed, press the ‘MIN’ button to see the previously-set value. Process measurement scale
is set to “1.00000” using the ‘MIN/MAX’ buttons. Store by pressing the ‘MENU’ button.

CF 67 35 M1291/N/0403 11279ML-02 Rev. A

For “RDG OF”, you may choose to enter a reference temperature offset here (e.g., “-100.00”) so that the display will
read deviation of the input from the boiling point (or some other temperature).

If “RDG.1 = 1” were chosen, then you go automatically into “RD.SC.OF”.

NOTE: Direct reading offset “RDG OF” now has programmable decimal point position. This makes the decimal
point independent of the display decimal point and allows larger offset values.

9.2.4 IN CNF (Input Configuration)

Input configuration is used to select:

• 50 or 60 Hz line frequency [INP.1]

• slow or fast read rate [INP.2]

• unipolar or bipolar inputs

• cold junction compensation [INP.5]

INP.1 and INP.2 are related to each other. If your power requirements require 50 Hz, you can have optimum
integration in FAST read mode (12/sec). In the FAST mode, you need a jumper in the
S1A position on the vertical Signal Input Board. If you set the SLOW read rate, this jumper should be removed to
avoid overloading the integrator. SLOW read rate produces less noise.

Count by is used to round off the meter values by 1’s, 2’s, 5’s, 10’s, 20’s, 50’s, or 100’s. This feature is normally set
to “001” so that the display shows all possible values for the least-significant digit.

If the combination of input-signal noise and selected resolution is high, however, your meter can round off the
display to the nearest 2, 5, 10, 20, 50 or even 100 digits. This can eliminate annoying display jitter without
introducing any filter time delays.

9.2.8 FIL.CNF (Filter Configuration)

Filter configuration is used to select:

• Adaptive Bandwidth Control (ABC) filtering or moving average filter [FIL.1]

• whether the value displayed on the meter is filtered or unfiltered [FIL.2]

• whether the value sent to the optional analog output is filtered or unfiltered [FIL.3]

“FIL.1=0” for Adaptive Bandwidth Control (ABC filtering, which averages over a larger number of samples when the
input is not moving, but drops down to no averaging for systematic input changes). “FIL.1=1” is for averaging over a
fixed number of samples. The number of samples to be used is selected in “FIL TI”.

“FIL.3=0” removes the selected filtering from the analog output (if that option is installed in your meter). “FIL.3=1”
puts the selected filtering on that output. Usually you choose “FIL.3=0”, relying on the signal conditioning available
at the device receiving the analog output data.

9.2.9 FIL TI (Filter Time Constant)

Filter time constant is used to determine the number of readings the meter will average before displaying an input
value. The choices are 001, 002, 004, 008, 016, 032, 064, or 128.

For fixed filtering, the averaged number of samples is fixed; for Automatic Bandwidth Control, the chosen value is
the maximum number of samples in the average computed by ABC when the input is not changing significantly
(ABC, for slowly-moving signals, filters by averaging the “TI” number of samples, but follows signal changes rapidly
by decreasing that averaging number).

Pressing the ‘MENU’ button stores your selection and moves on to “RESET 1” and then to “RUN” (unless setpoints,
outputs, or communications have been unlocked for programming change).

10.0 SETPOINTS/ALARMS

Setpoints 1 through 4 can be configured for a very large variety of zone and level signaling.

SP1 and SP2 have balanced configurable hysteresis and are non-latching, suitable for control-level signaling. SP3
and SP4 are often used as ALarm 1 and ALarm 2, because they have single sided hysteresis and can be
configured for latching action.

The levels of these setpoints are entered during run mode via the front-panel pushbuttons (refer to Section 10.11).
Many performance options are entered during the configuration mode (refer to Sections 10.2 through 10.10).

CF 67 49 M1291/N/0403 11279ML-02 Rev. A

10.1 Features Overview

1. Four full-range levels with many menu programmable features.

2. Independent operation or ganged action (including guard-band assignments).

3. Active above or below level, outside or inside band.

4. SP1 and SP2 have configurable hysteresis, 50% on either side of setpoint.

5. SP3 and SP4 have configurable hysteresis, 100% on inactive side.

6. SP3 and SP4 is configurable for latching action.

7. Setpoint levels can be compared to the unfiltered or filtered input signal measurements.

8. Configurable delays in alarm action.

9. Individual front-panel LED indicators.

10. Four (4) open-collector transistor outputs with clamping diodes, are isolated from signal input.

11. Setpoints can be displayed and reset as desired without interrupting measurements.

Setpoints 1 and 2 have selectable hysteresis, allocated 50% on either side of the setpoint level. A single setpoint
can now generate on/off control signals for an operating region defined by the hysteresis. Refer to Figures 10-1 and
10-2 to understand how hysteresis works:

Figure 10-1. Setpoints 1 & 2 Action (Setpoint at 100 with 4% hysteresis)

These two setpoints have selectable single-sided hysteresis. When used as alarms, the action is immediate (unless
a delay is programmed) going into the alarm zone but turning off is deferred (if latching is not programmed) by the
hysteresis amount.

Figure 10-2. Setpoints 3 & 4 Action (for Low Alarm with Relay on at -100, relay off at –96 with a hysteresis of 4)

You are now able to program the setpoint features (as described in the following sections).

10.2 Unlocking The Features

All setpoint values and features can be set via the front-panel buttons or the optional serial communications boards
(RS-232 or RS-422/485). Control from the front-panel buttons can be locked out by jumpers on S3A and S3C on
the main board or by setting lockout bits “L3C.2”, and “L3C.6” in Lockout configuration “L3 CNF”.

1. Check that main board jumpers S3A and S3C are installed (to permit memory storage of program and data

along with button controls).

NOTE: Jumper S3B should NOT be installed. This jumper is reserved for factory recalibration!

recommended only when other external over-range indicators are present).

10. Press the ‘MENU’ button to store your selections and advance to “AL CNF” (Alarm Configuration).

10.4 Deviation Function For Alarms

Deviation functions apply to Alarms 1 and 2 (Setpoints 3 and 4) and act as buffer zones to control setpoint action.
The Alarm 1 deviation is the sum of the Alarm 1 value plus the Setpoint 1 value; the Alarm 2 deviation is the Alarm
2 value plus the Setpoint 2 value. The four types of deviation functions are Process (no deviation), High, Low, and
Deadband. The following illustrate the ways in which the deviation function alters the alarm response.

last bit, which controls “SP 3” and “SP 4” LATCH reset.

1.“ALC.1=0” makes Alarm 1 (Setpoint 3) active above the Setpoint value.

“ALC.1=1” makes Alarm 1 (Setpoint 3) active below the Setpoint value.

When Alarm 1 (Setpoint 3) is assigned to place a band about the Setpoint 1 level (by setting “ALF.1=3”, described
in Section 10.6), “ALC.1=0” makes Alarm 1 (Setpoint 3) active ABOVE and BELOW the band (OUTSIDE the band),
with the chosen hysteresis for Alarm 1 (Setpoint 3) now inside the band. If “ALC.1=1”, Alarm 1 (Setpoint 3) is active
INSIDE the band, with the chosen hysteresis for Alarm 1 (Setpoint 3) now outside the band.

then “RUN” and proceed with normal operation (go into run mode).

CF 67 54 M1291/N/0403 11279ML-02 Rev. A

10.11 Entering Setpoint Levels (In Run Mode)

When you have completed selecting the setpoint(s) (and other features), the last press of the ‘MENU’ button stores
any changes and the meter will automatically return to the run mode (the display will momentarily display
“RESET2”). The stored values are placed into operation, and the meter proceeds with normal measurements.

Now you can view and reset all four setpoint levels.

1. Press the ‘SETPTS’ button. The meter now starts its setpoint display cycle; every 15 seconds, the display

flashes the SP number, and then displays the value of that setpoint, with a flashing left-hand digit.

2. You can restart the time-out of any of these display intervals by pressing the ‘MIN’ button (to shift the flashing

[alterable] digit position), or by pressing the ‘MAX’ button (to increment the value of that digit).

3. When you change the value of any setpoint and then decide to revert to the original value instead, just press

the ‘RESET’ button or allow the display to return to “RUN” at the end of its cycle. The meter does not store a
new value for the setpoint in either case.

4. To save a newly entered setpoint value, press the ‘SETPTS’ button again.

5. You may return to viewing the measurements by pressing the ‘RESET’ button or repeatedly pressing the

‘SETPTS’ button (or by letting the meter complete its setpoint display cycle).

11.0 PEAK AND VALLEY READINGS

The meter examines every new reading to see if it is greater than the stored PEAK or less than the stored VALLEY
readings.

If you have unlocked access to these values with “L1C.5=0” and “L1C.6=0” (part of the first lockout byte “L1 CNF”),
you can view the PEAK (“HI RDG”) by pressing the ‘MAX’ button, or the VALLEY (“LO RDG”) by pressing the ‘MIN’
button while in the run mode.

Selection of either PEAK or VALLEY causes the display to flash giving the indication that it is NOT the current
measurement value. If the meter measures a more extreme value while displaying the PEAK or VALLEY
measurement, the new value will immediately replace the old.

Unlike the setpoint display, there is no time out period. Press the ‘SETPTS’ button or ‘MENU’ button to return to
current value display WITHOUT resetting the PEAK or VALLEY memory.

Press the ‘RESET’ button to return to run mode and start a new PEAK/VALLEY measurement period.

The BCD option can be programmed to read the PEAK (but not the VALLEY) instead of the current measurement
(refer to Section 13).

Both PEAK and VALLEY readings (and/or a PEAK/VALLEY status summary character) can be transmitted by the
RS-232 or RS-422/485 digital communications (refer to Section 15).

The PEAK or VALLEY value can be transmitted via the optional analog output board (refer to Section 12).

12.0 ANALOG OUTPUT OPTION

If you received your meter with the optional analog board installed, you should not have to enter the trim data as
described in Section 12.5.

CF 67 55 M1291/N/0403 11279ML-02 Rev. A

Your meter converts display readings into an independently-scaled and-offset isolated voltage and/or current
analog output. Isolation is accomplished via opto-isolators on the board. Your meter has the capability of
transmitting SIMULTANEOUS voltage and current outputs although when this is done, the current analog output is
not as accurate.

12.1 Features Overview

1. Precise analog levels are generated from digital code using a proprietary ASIC chip.

2. Voltage (to 10 V) is available at the same time as current (to 22 mA), but the total current drawn should not

exceed 24 mA.

3. Load resistance for the voltage output can be as low as 500 ohms (20 mA at 10 V out) when current output is

not used.

4. Loop resistance for the current output can be as high as 600 ohms (12 volts compliance) with negligible current

from the voltage output.

5. Both outputs are galvanically isolated from both power and measurement circuits of the meter: 354 V per IEC

spacing, 500 V test.

6. Precision calibration is applied by the meter to either the voltage output or the current output (but not to both

simultaneously). When both outputs are used simultaneously, the non-calibrated output is stable but does
require external adjustment if fine-trimming is required.

7. Independent, 15-bit resolution OuTput SCale and Offset (OT.SC.OF) can convert a wide range of meter

readings to the desired current or voltage output span.

8. The output resolution permits good accuracy for turndown ratios (offset/span) as high as 100:1.

9. 50°to 104°F (10°to 40°C) accuracy within 0.1% after installation calibration.

10. 10% to 90% step response time is 50 milliseconds (plus filter delay, if any, programmed for the analog output).

11. Configurable so that output will track the PEAK or VALLEY measurement.

12.2 Unlocking

1. Press the ‘MENU’ button until “L3 CNF” is displayed, then press the ‘MIN’ button until “L3C.7” is displayed.

2. Press the ‘MAX’ button (if required) to set “L3C.7=0”, unlocking the choice of current or voltage as the

calibrated output.

3. Press the ‘MIN’ button (and the ‘MAX’ button if required) to set “L3C.8=0”, unlocking OT.SC.OF.

4. Press the ‘MENU’ button to store these choices.

5. If your analog board is NEWLY INSTALLED, you will need to enter the four trimming constants (refer to the

one-time only procedure in Section 12.5). To unlock this feature, press the ‘MIN’ button and then the ‘MAX’
button to set “L4C.6=0” and store by pressing the ‘MENU’ button.

12.3 OUT.CNF: Configuring The Output

1. Press the ‘MENU’ button until “OUT.CNF” is displayed, then press the ‘MIN’ button to display “OUT.1=0” or

“OUT.1=1”.

2. Press the ‘MAX’ button to set “OUT.1=1”if you wish the analog output to be driven at once when you return to

run mode. (You can leave this as “OUT.1=0” and complete all the other programming if you wish to activate the
analog output at a later time by returning to this configuration bit).

3. Press the ‘MIN’ button (and the ‘MAX’ button if required) and set “OUT.2=0” for calibrated VOLT output (0-1 V,

0-5 V, 1-5 V, or 0-10 V) or “OUT.2=1” for calibrated CURRENT (0-20 mA or 4-20 mA) output.

4. Press the ‘MENU’ button to store these choices (the rest of the “OUT.CNF” byte controls BCD and display-

flashing features).

After pressing the ‘MENU’ button again, you advance to “OT.SC.OF” (Output Scale and Offset).

12.4 OT.SC.OF: Setting Output Scale And Offset

Any two data points can be used here: a data point is specified by a value of the display (“READ”) and the desired
output (“OUTPT”) for that display.

1. Press the ‘MIN’ button to see “READ1” and then use the ‘MIN’ and ‘MAX’ buttons to enter a small display value,

for example, “000.000”, where the center decimal point position is used as an example.

2. Store this value by pressing the ‘MENU’ button and then you see “OUTPT1”. Use the ‘MIN’ and ‘MAX’ buttons

to specify the desired output value, for example, “04.0000” if current calibration had been selected (“OUT.2=1”),
or “00.0000” for voltage.

CF 67 56 M1291/N/0403 11279ML-02 Rev. A

3. Store this value by pressing the ‘MENU’ button and then advance to “READ2”. Use the ‘MIN’ and ‘MAX’ buttons

to enter a large display value, for example, “123.456”, for the display that you want the analog output at full
scale.

4. Store this value by pressing the ‘MENU’ button and then advance to “OUTPT2”. Use the ‘MIN’ and ‘MAX’

buttons to enter the desired output for the display value in step 3. For example, enter “20.0000” for calibrated
current or “10.0000” for calibrated voltage.

5. Press the ‘MENU’ button to store. Press the ‘RESET’ button two times to return to run mode and check

calibration points, unless your analog output board is newly installed; in this case, follow Section 12.5.

12.5 Board Installation: Entering The Trim Data

To precisely calibrate your analog output board with your meter, each analog output board has been supplied with
voltage and current zero trim values printed on the board. “CAL VZ” is for the voltage output and “CALmAZ” is for
the current output.

Similarly, the fine trim for output gain is “CAL VS” for the voltage output and “CALmAS” for the current output.

These 4 data points are obtained from the factory calibration of each analog output board and are inscribed on the
top edge of each board, as shown in Figure 12-1.

Figure 12-1. Analog Option Board and Connection Diagram at P5.

If you are installing an analog output board, follow this “one time only” procedure:

1. Write down the four (4) numbers inscribed on the top edge of your analog output board below:

CAL VZ=
CAL VS=
CALmAZ=
CALmAS=

2. “Reveal the main board” and install the analog output board using the procedures outlined in Section 5.2.

3. Attach connector wires, insert connectors, and apply power to the meter as described in Section 5.3.

4. If not already unlocked, press the ‘MENU’ button until “L4 CNF” is displayed and press the ‘MIN’ button six

times. Now press the ‘MAX’ button to set “L4C.6=0”.

5. Press the ‘MENU’ button to store and advance to “CAL VZ”. Use the ‘MIN’ and ‘MAX’ buttons to enter the

value (recorded from the edge of the board).

6. Press the ‘MENU’ button to store and advance to “CAL VS”. Use the ‘MIN’ and ‘MAX’ buttons to enter the

value.

7. Repeat for “CALmAZ”.

8. Repeat for “CALmAS”.

9. Press the ‘MENU’ button to store your entries and then you will see “C.JUN.OF”. Press the ‘RESET’ button two

times and you will see “RESET2”, followed by “RUN”. Verify your calibration points for the analog output.

10. Jumper S1-A does not need to be installed, but located in a storage position.

CF 67 57 M1291/N/0403 11279ML-02 Rev. A

12.6 Filter Configuration FIL.CNF Value To Be Transmitted On Analog Output

1. Press the ‘MENU’ button until the display shows “FIL.CNF”.

2. Press the ‘MAX’ button until the display shows “FIL.3=0”, “FIL.3=1”, “FIL.3=2”, or “FIL.3=3”.

3. “FIL.3=0” Transmits the unfiltered value of your signal input.
“FIL.3=1” Transmits the filtered value of your signal input.
“FIL.3=2” Transmits the recorded PEAK (“HI RDG”) value(s).
“FIL.3=3” Transmits the recorded VALLEY (“LO RDG”) value(s).

4. Press the ‘MENU’ button to store your selection or changes and the meter will advance to “FIL TI” (Filter Time

Constant).

Press the ‘RESET’ button two times to return to the run mode.

12.7 Wiring/Connections

WARNING: Do not connect ac power to you meter until you have completed all input and output connections.
Failure to do so may result in injury! This device must only be installed electrically by a specially trained electrician
with corresponding qualifications.

13.3 Interconnect Board

For mechanical support and electrical interconnection, each BCD board is shipped with a small 5-pin
INTERCONNECT board. Insert onto the main board pins immediately behind the right-hand side of the display
board. The BCD board itself (component side down) is 13-4 then plugged into the interconnect board at J20, with
the PCB connection fingers protruding from the case rear. For assembly detail, refer to Figure 5-5 (in Section 5).

13.4 50-Line Cable Compatibility

The 40 lines of the BCD connector are compatible with lines 9 through 48 of some 50-line busses (left-most 8 and
right-most 2 are not used by this BCD option).

CF 67 59 M1291/N/0403 11279ML-02 Rev. A

13.5 Selecting The Source Of BCD Data: “OUT .CNF”

If “L3C.7=0” has been selected to unlock the Output Configuration byte, set “OUT.3=1” to send data to this BCD
board. “OUT.4=0” selects that data as the DISPLAYED (current) measurement value. “OUT.4=1” sends the PEAK
(HI) value to the BCD. Save your selection by pressing the ‘MENU’ button.

13.6 Hold Control

P8-U17 is the HOLD line, referenced to the same ground as the BCD outputs (on P8-L15 and P8-L3). Pulling this
line low freezes the BCD outputs (useful for a slow reading device or asymmetric cable delays). When released, all
6 digits of the BCD data are updated together.

13.7 Data Ready Timing Pulses

The tri-state BCD outputs are always valid (to within a few nanoseconds; a single update pulse controls all the
digits).
To generate a timing marker, P8-L16, DATA READY, goes active low for approximately 200 microseconds at the
time of each BCD update. The polarity of this line is NOT CHANGED by S8, the data polarity control jumper.

13.8 Bringing Out The BCD Overflow Line

P8-U18 can be used for BCD OVERFLOW by inserting jumper S1A. If this line is used for another purpose by
some other equipment on the BCD bus, remove this jumper.

13.9 3 Digit At A Time Multiplex

When jumpers S2A, S3A, and S4A are used, P8-L20 and S5C control when the upper 3 digits of the 6-digit BCD
value appear on the output line (P8-U9 through P8-L14).

With jumper S5C, a LOW level on P8-L20 activates those upper 3 digit outputs; a high or open level disables those
digits.

With jumper S5C removed, a high or open level on P8-L20 enables those upper 3 digits and a low level disables
them.

When the upper 3 digits are NOT enabled, the lower 3 digits can be enabled in just the same way by jumper S5A
and P8-U20, and they now appear on the same 12 lines.

13.10 6 Digit At A Time Card Address

Jumpers S2A and S4A are removed for full parallel (6-digit output).

If jumper S3A is installed, the outputs are enabled by line P8-L20 ALONE: a low level enables the outputs when
jumper S5C is installed, and a high or open level does the job if S5C is removed.

When jumper S3A is removed, the outputs are enabled only when the selected 4-line address is applied to P8-U19,
L19, U20 and L20. Each of these four is exclusive-OR’d with its jumper, and the following four outputs are AND’d
to create a 1 of 16 enable code.

If jumper S5A is installed, P8-U20 must be LOW to enable the card (BIT 2).
If jumper S5C is installed, P8-L20 must be LOW to enable the card (BIT 1).
If jumper S5E is installed, P8-U19 must be LOW to enable the card (BIT 8).
If jumper S5G is installed, P8-L19 must be LOW to complete enabling the card outputs (BIT 4).

CF 67 60 M1291/N/0403 11279ML-02 Rev. A

Figure 13-3. Address Programming Chart for 4-line Address

NOTE: “X” in chart indicates jumper that must be installed.

EXAMPLE: For a positive true address of 03, install jumpers S5-G and S5-E.

If any of these jumpers are removed, the corresponding line must go HIGH or OPEN to assist the card enable; if all
four jumpers are missing, for example, the card outputs are enabled ONLY when all four lines are HIGH or OPEN,
a ground on any of the four input lines causes the outputs to go to the high impedance state.

13.11 Select Data Polarity: Jumper S8

Inserting the jumper in S8B (the usual shipping position) makes the output data (including decimal point code)
positive-true. Placing the jumper in S8A converts the data to negative-true.

13.12 Decimal Point Address Code

P8-U15, P8-L8 and P8-U8 output a 3-bit positive-true binary code for the location of the decimal point: “001” for the
extreme right position and “110” for the extreme left position (just to the right of the left-hand digit).

Panel-mounted printers, however, may require an inverted/shifted decimal point code. You can create this by
setting “OUT.5=1” in the “OUT.CNF” byte (unlocked by setting “L1C.7=0”), rather than the normal “OUT.5=0”.

13.13 Applying Non-Isolated/Isolated Power

Non-isolated power from the meter is connected to this board by inserting jumpers S6A, S6B, S7A, and S7B
(bridging the isolation separation distance on the board). Current drawn is less than 10 mA.

To isolate these outputs from the other meter circuits, remove the four jumpers described earlier, and connect an
external, nominal 5 V supply to P8-L17, with its ground return connected to P8-L15.

13.14 Driving A Printer

Direct connection of the 24 BCD lines and the 3 decimal point address lines is all that is needed for positive-true
printers that accept a binary-coded decimal point address (which do not print the decimal point).

If your printer has more than 6 digits, tie the unused inputs to ground or V+ or leave open (whichever produces
blanks in those locations).

For negative-true decimal pint addresses, found in some panel-mounted printers, set “OUT.5=1” (part of menu item
“OUT.CNF”, unlocked by “L1C.7=0”).

14. RELAY OPTIONS

14.1 Features Overview

The Dual Relay Output Board and 4 Relay Output Board provides two isolated (354 v per IEC spacing, 500 test), 7­ampere Form-C electro-mechanical relays that enable setpoint-triggered switching to an external device (plus two

15.0 RS-232 OR RS-485 OPTION BOARD

15.1 Features Overview

The Isolated Serial RS-232 Communications Board provides an isolated digital communications channel between a
single meter and another meter or device, or between a single meter and a computer. The Isolated Serial RS-485
Communications Board adheres to the IEC standard, providing an intelligent device – but can actually address up
to 199 devices.

1. When you order either option board, you will also receive a six foot communications cable that plugs into J4.
Optional female 9-pin and 25-pin “D” computer connector-adapters are offered for either RS-232 or RS-422/485
hookup.

2. The latest Operation and Communication Manual as well as free configuration software and ActiveX controls
are available from the website listed in this manual or on the CD-ROM enclosed with your shipment.

3. The communications board you ordered, plugs into the main board socket (P11 connects into J11 next to the
transformer) with the 6-pin telephone socket. J4 is then protruding out of the rear of the case.

4. Choose baud rate from 300 to 19200. Standard factory setting is 9600.

5. Wide choice of commands and message formats available.

15.2 Front-Panel Pushbutton Configuration

Setup configuration can be accomplished via the front panel buttons or via your computer if you use the
configuration setup program. If you are going to use a computer, your choices include “AUTO SET” or “MANUAL
SET” for establishing communication with your meter. “AUTO SET” cycles through the possible combinations of
baud rate, parity and stop bits to find a match for your meter settings. For faster action, you may enter the values
for your meter via “MANUAL SET”.

If your meter communications settings are unknown or need changing, you can insert the factory-set values with
the front panel buttons (or, after communications has been established, from your keyboard).

1. Unlock the communications bits by setting “L4C.1=0”, “L4C.2=0”, “L4C.3=0”, “L4C.4=0” and “L4C.5=0”.

2. Press the ‘MENU’ button until “BAUD” is displayed, then press the ‘MAX’ button until the baud rate you require
is displayed. Press the ‘MENU’ button to store this choice and your meter will display “SERCNF”.

3. Press the ‘MIN’ button until you see the display show “SER.1=0” for no parity, “SER.1=1” for odd parity, or
“SER.1=2” for even parity. Press the ‘MAX’ button to select the parity required for your system. Once you have
done that, press the ‘MIN’ button and advance to “SER.2=0” or “SER.2=1”.

4. By pressing the ‘MAX’ button you can select the “SER.2” value. Setting “SER.2=0” picks the value to one stop
bit; “SER.2=1” selects two stop bits. Select “SER.2=0”.

5. Pressing the ‘MENU’ button stores these choices and then the meter advances to “ADDRES”. Use the ‘MAX’
button to set to “001” (unless your meter is one of several on an RS-485 bus, in which case you must give a
different address to each device and use those addresses when communicating from your computer).

6. Press the ‘MENU’ button again and press the ‘RESET’ button two times to return to the run mode. The
remaining communications format and options are set from your keyboard.

16.0 EXTERNAL CONTROL LINES

P2, the 20-pin connector at the rear of the main board, connects to the setpoint transistor collectors and permits
remote control of significant meter features.

The meter case label gives the names (abbreviated functions) of each of the twenty pins of P2, the center-bottom
connector. Refer to Figure 16-1.

Figure 16-1. Connector Label Detail

CF 67 65 M1291/N/0403 11279ML-02 Rev. A

16.1 Tare (PIN 1)

Tare is available when pin P2-1 and P2-4 are connected to a momentary contact switch. This feature allows you to
automatically zero your meter when the switch is activated.

16.2 Peak (PIN 2)

When this is connected to P2-4 by an external switch, the meter displays the stored PEAK (“HI RDG”) value rather
than the current reading. The display flashes to distinguish this value.

16.3 Valley (PIN 3)

When this is connected to P2-4 by an external switch, the meter displays the stored valley (“LO RDG”) value rather
than the current reading. The display flashes to distinguish this value.

16.4 SWLIN2 (PIN 4)

Completes the circuit for any of the above three signals.

16.5 Peak & Valley Or External Reset (PIN 5)

Connecting this to ground (P2-7) when “RDG.7=0” has been programmed causes a “HARD” RESET (when you see
“RESET2” on the display). If you set “RDG.7=1”, grounding causes only a PEAK/VALLEY RESET.

16.6 Push To CAL (PIN 6)

The Push To Cal feature is only available for the Strain Gauge meter and the Universal meter when configured for
the BRIDGE mode.

This feature allows you to connect an external calibration resistor to P2-6 and P2-14 at the rear of the meter. Note:
Use a one-way switch only.

If your selected calibration resistor is to be mounted externally (in series with your switch), install a SHORT in place
of R35.
Note: This short is already installed at the factory.

If your selected calibration resistor is to be mounted internally, solder it in the holes of R35 on the input board. See
Figure 5.6.

16.7 Digital Ground (PIN 7)

This is a non-isolated ground to be used for the digital controls provided on this P2 connector.

WARNING: THIS METER GROUND IS NOT ISOLATED FROM THE SIGNAL INPUT AND SHOULD NOT BE
CONNECTED TO EXTERNALLY-GROUNDED DEVICES UNLESS ISOLATION IS PROVIDED EITHER AT THE
SIGNAL INPUT OR AT THIS EXTERNAL-LOGIC CONNECTION.

16.8 +5 V (PIN 8)

Up to 20 mA is available for driving external devices, but isolation should be provided if there is a possibility of
common mode (ground) currents, since this supply is NOT isolated from the signal input.

16.9 Display Hold (PIN 9)

Grounding this pin to P2-7 freezes the display value. However, the meter continues to take new samples and
update the other outputs, such as Analog Output, BCD, Setpoints/Alarms, and Peak/Valley.

16.10 Lockout EEPROM (And ‘MENU’ Button) (PIN 10)

Grounding this pin to P2-7 stops any configuration changes and new storage into the non-volatile memory, and
when in run mode does not allow entry into the setup mode when the ‘MENU’ button is pressed.

CF 67 66 M1291/N/0403 11279ML-02 Rev. A

16.11 Print Command And/Or Reset Of Alarms (PIN 11)

Grounding this pin to P2-7 when “BUS.8=1” has been programmed will initiate a meter printout via serial
communications in the format previously selected. If “ALC.8=1” it causes the alarm latches to reset.

16.12 Nonstandard RX (PIN 12) And Nonstandard TX (PIN 13)

These two pins allow digital communications with the meter using 5 V CMOS logic levels and RS-232 protocols and
format. This access is normally reserved for specialized equipment communication in a calibration lab or at the
factory.

16.13 Push to CAL (PIN 14)

See Section 16.6.

16.14 +V EXT (PIN 15)

This is the pin on which to bring in isolated external 5 to 30 V to power the snubbing diodes of the four
setpoint/alarm open-collector transistors.

16.15 SP1 (PIN 16)

The open-collector of the first setpoint transistor (can carry 150 mA).

16.16 SP2 (PIN 17)

The open-collector of the second setpoint transistor (can carry 150 mA).

16.17 AL1 (PIN 18)

The open-collector of the third setpoint (first alarm) transistor (can carry 150 mA).

16.18 AL2 (PIN 19)

The open-collector of the fourth setpoint (second alarm) transistor (can carry 150 mA).

16.19 RTN EXT (PIN 20)

This is the return to the external ground (P2-20) of the external power for the setpoint transistors and snubbing
diodes brought in on P2-15, 16, 17, 18 and 19. Figure 16-2 shows an example of a circuit using an external relay
with SP1 (Setpoint 1). If a solid-state relay is used, delete connection to Pin 15.

17.1 Error Mode Messages

17.1.1 Flashing 999999 (Numerical Overflow)

The maximum number of counts in the display cannot exceed –99999 or 999999. If, by moving the ACTIVE
decimal point one or more places to the left, you cause the display to move beyond the maximum number of counts
it is capable of showing (for example, 12345.0 to 12345.00), the display will indicate the overflow by flashing
“999999”.

17.1.2 Flashing ERR O1 (Offset Overflow)

When an offset value has been entered and then the ACTIVE decimal point has been moved one or more places to
the left, causing the offset display reading to move beyond the maximum number of counts it is capable of showing
(for example, 1000.00 to 1000.000), the display will go into offset overflow.
NOTE: The meter will only display 6 digits (999999) maximum.

17.1.3 Flashing ERR O2 (Setpoint Overflow)

After a Setpoint (or Alarm) value has been entered and then the ACTIVE decimal point has been moved one or
more places to the left, causing the setpoint display reading to move beyond the number of counts it is capable of
showing (for example, setpoint at 100.00 and then a decimal point change to 100.0000), the display will indicate the
SETPOINT OVERFLOW by momentarily flashing “ERR 02” before returning to the run mode. NOTE: The meter
will only display 6 digits (999999) maximum.

17.1.4 NOSTOR & STORED (Programming Entries In EEPROM)

If you are in the configuration mode and you make a CHANGE to any setup parameter (for example, changing
“RDG.1 = 1” to “RDG.1 = 0”) and press the ‘MENU’ button, the display will MOMENTARILY flash either “STORED”
or “NOSTOR” and then go to the next menu item. If you are in a submenu, this will only occur when you press the
‘MENU’ button to go to the next menu item.

17.1.5 Flashing +OVLD (Positive Input Overload)

If the input signal exceeds the range selected (for example, 0-100 mV range selected and greater than 200 mV is
applied to the input), the display will flash a “+OVLD”.

17.1.6 Flashing +OPEN (Open Sensor Indication)

Coupled with the proper jumper selection, the display will indicate an open sensor.

17.1.7 Flashing -OPEN (Open Sensor Indication)

Coupled with the proper jumper selection, a “-OPEN” indicates the input is below the bottom limit of the range
selected.

17.1.8 Flashing I OVSC (Input Overscale)

This display occurs when the input scale and/or offset applied to the input signal causes the display to go into a
numerical overflow.

17.1.9 Flashing R OVSC (Reading Overscale)

This display occurs when the reading scale and/or offset applied to the input signal causes the display to go into a
numerical overflow.

17.1.10 Flashing CB OVF (Count By Overflow)

When a display value near the maximum display capability is forced into a numerical overflow by changing the CNT
BY menu (for example, the display reads 999997 and the count by is changed from 001 to 005 and rounds the
display up to 1000000).

17.1.11 Flashing UOM.OVF (Unit Of Measure Overflow)

If a unit of measure is selected and you are near the full-scale capability of the display and in the ACTIVE decimal
mode, the display will shift one digit to the left (for example, to a display of 1065.33 you add a unit of measure such
as “F” for a display of 1065.33F), the display will flash “UOM.OVF”.

17.2 Troubleshooting Guide

99999

POSSIBLE CAUSE: Active decimal point change driving the display into numerical overload.
TO CORRECT: Press the ‘MAX’ button to reset the entire display to all zeros, then enter a revised number into the
submenu item that caused the overflow.

ERR 01

POSSIBLE CAUSE: Active decimal (“RDG.2=0”) has been selected and/or DEC PT (decimal point) position has been
moved one or more places to the left driving the programmed offset value into numerical overflow.
TO CORRECT: Press the ‘MENU’ button and the meter will show the left most decimal point position possible for the
chosen offset: by pressing the ‘MENU’ button again this revised entry is stored. Alternately, the amount of RDG.OF
may be reduced to get the decimal point further to the left.

ERR 02

POSSIBLE CAUSE: Active decimal (RDG.2) has been selected and/or DEC PT (decimal point) position has been
moved one or more places to the left driving the programmed Setpoint value into numerical overflow.
TO CORRECT: Display will flash “ERR 02” message for a short period of time, then automatically correct the
setpoint’s decimal point position and move to the next menu item. Press the ‘SETPT’ button until the meter displays
flashing “999999”. Then press the ‘MAX’ button to reset the display to “000000” and enter a new valid setpoint value.

+OVLD

POSSIBLE CAUSE: The positive input CURRENT & VOLTAGE exceeds the input range selected.
TO CORRECT: Check both the input range and the actual input to find the error condition and either reduce the input
or change jumpers to a higher input range for more input attenuation.

-OVLD

POSSIBLE CAUSE: The negative input voltage exceeds the input range selected.
TO CORRECT: Check both the input range and the actual input to find the error condition and either reduce the input
or change jumpers to a higher input range for more input attenuation.

+OPEN

POSSIBLE CAUSE: Input sensor is open or broken, or the connection to the meter is open or broken.
Input sensor is not wired to the proper input terminals.
TO CORRECT: Check thermocouple or RTD wiring.

-OPEN

POSSIBLE CAUSE: The input sensor is open or broken, or the connection to the meter is open or broken.
The input sensor is not wired to the proper input terminals. The input signal is below the minimum specified (refer to
Section 18, Specifications).
TO CORRECT: When jumper S2R on the signal input board is used, this will be indicated if a sensor lead is broken
or otherwise opened.
Check thermocouple or RTD wiring.

I OVSC

POSSIBLE CAUSE: The input scale and/or offset values chosen are large enough to drive the display into numerical
overflow.
TO CORRECT: Reduce the input and/or the input scaling/offset. Refer to “IN.SC.OF” in Section 9.2.5.

R OVSC

POSSIBLE CAUSE: The reading scale and/or offset values chosen are large enough to drive the display into
numerical overflow.
TO CORRECT: Reduce the READING scale/offset and/or move the active decimal point to the right.
Reducing INPUT scale/offset is not required, because the input over scale message has higher priority than this
message and would be displayed if there were an input over scale.

CB OVF

POSSIBLE CAUSE: CNT BY (count by value) has been changed causing the display to round up to a numerical
overflow.

CF 67 69 M1291/N/0403 11279ML-02 Rev. A

TO CORRECT: Reduce the “CNT BY” count by value to 001. If you have an active decimal point selected, move
the decimal point one or more positions to the right.

UOM.OVF

POSSIBLE CAUSE: Selection of unit of measure displayed (“RDG.6=0”) moves the display reading
one place to the left causing a numerical overflow.
TO CORRECT: If you have an active decimal point, move he decimal point position one or more positions to the
right.

SERIAL

POSSIBLE CAUSE: A configuring change has been attempted via the front panel buttons while the serial
communications port is actively communicating with the meter.
TO CORRECT: Either lockout the front panel buttons by removing the jumpers S3A & S3C or disconnect the serial
communications option.
