CONFIGURING
THE METER
USING
OUTPUT CONFIGURATION ("OT.CF")
Note: Refer to Table 6-1 for a summary list of menu configuration.
Output Configuration ("OT.CF") is not active unless your meter
has analog output capabilities. The menu will display whether analog output
is present or not. Analog output must be ordered at the time of purchase.
Use Output Configuration ("OT.CF") to select the following:
* To enable or disable the analog output
* To select if the analog output is current or voltage
* To select if the analog output is regular or proportional
Enabling or Disabling the
Analog Output
To enable or disable the analog output, follow these steps:
1. Press the MENU button until the meter shows "OT.CF".
2. Press the /TARE
button.
The meter shows one of the following:
* "O.1=E" (Analog output enabled) (default)
* "O.1=D" (Analog output disabled)
3. Press the /MAX
button to toggle between available choices.
4. Press the /TARE
button to select analog output as current/voltage or press the MENU
button to store your selection and enter "OT.S.O" (Output Scale
and Offset).
Selecting
Analog Output as Current or Voltage
1. Press the MENU button until it shows "OT.CF",
then press the /TARE
button twice.
or Press the /TARE
button from O.1.
The meter shows one of the following:
* "O.2=C" (Analog output = current) (default)
* "O.2=V" (Analog output = voltage)
2. Press the /MAX
button to toggle between available choices.
3. Press the /TARE
button to select analog output or proportional control or press the MENU
button to store your selection and enter "OT.SO" (Output Scale
and Offset).
Selecting Analog Output or Proportional
Control
Use this section to select if the meter will transmit an analog signal
proportional to the display readings, or proportional to the error signal
between the display reading and Setpoint 1.
Proportional Control Analog Option is not available for models without
Relay Option.
1. Press the MENU button until it shows "OT.CF",
then press the /TARE
button twice. or Press the /TARE
button from 0.2.
The meter shows one of the following:
"O.3=A" (Analog output is regular) (Default)
"O.3=P" (Analog output is proportional)
2. Press the /MAX
button to toggle between available choices.
3a. If you select O.3 to equal A, press the MENU
button to store your selection. The meter momentarily shows "STRD",
followed by "OT.S.O" (Output Scale and Offset).
3b. If you select O.3 to equal P, press the /TARE
button.
The meter shows one of the following:
"O.4=D" (Proportional analog output is DIRECT ACTING)
"O.4=R" (Proportional analog output is REVERSE ACTING).
4. Press the /MAX
button to toggle between available choices.
5. Press the MENU button to store your selections. The meter
momentarily shows "STRD", followed by "P.BND" (Proportional
Band).
Additionally, if you select O.2 to equal V (Analog output to be
voltage), press the /TARE
button.
One of the following displays:
"O.5=F" (Proportional 0-10 V analog output)
"O.5=H" (Proportional 0-5 V analog output).
6. Press the /MAX
button to toggle between available choices.
7. Press the MENU button to store your selections. The meter
momentarily shows "STRD", followed by "P.BND" (Proportional
Band)
SELECTING PROPORTIONAL BAND
(P.BND)
Proportional Band (P.BND) is not active unless your meter has analog
output and relay capabilities. The menu will display whether analog output
is present or not.
- A proportional
controller's output is linearly proportional to the change of the
error signal, whenever the signal is within 2 prescribed values (Proportional
Band).
- There are three
(3) points of interest on the proportional controller transfer curve.
-
The first is the magnitude
of error signal that drives controller to on (e.g. 20 mA out for 4-20
mA).
The second point of interest is the magnitude of the error signal
that drives the controller output to ôfull offö (e.g. 4 mA out on 4-20
mA). These two (2) points need not be equally spaced on either side
of the zero error point.
The third is the factor "Offset" and it is the output value of the
controller which causes zero error.

To select the proportional band for your proportional controller, follow
these steps:
1. Press the MENU button until the meter shows "P.BND".
Note: If P.BND menu doesnÆt show, set 0.3=P on Menu
OT.CF.
Remember to press /TARE
when OT.CF is displayed until 0.3=A, then press /MAX,
unit will show 0.3=P. Pressing the MENU button will store
the selection.
2. Press the /TARE
button. The meter shows last previously stored 4- digit number (0000 through
9999) with flashing 4th digit.
3. Press the /MAX
button to change the value of the flashing digit. If you continue to press
the /MAX button,
the flashing digit's value continues to change.
4. Press the /TARE
button to scroll to the next digit.
5. Press the MENU button to store your selection. The meter
shows "STRD", followed by "M.RST" (Manual Reset)
USING
MANUAL RESET (M.RST)
Refer to Table 6-1 for a summary list of menu configuration.
Manual Reset (M.RST) is not active unless your meter has analog
output and relay capabilities. The menu will display whether analog output
is present or not. This feature allows you to offset the error that may
occur with your setpoint. In order to determine the amount of error, you
must compare your display value to the setpoint 1 value. The difference
between these two values (display - setpoint 1) is the amount of error
that you may want to enter into Manual Reset (M.RST). The value
of M.RST must be less than P.BND/2. Larger values will not
be accepted and the meter will display "ER 4" (flashing).
1. Press the MENU button until "M.RST" displays.
Note: This menu ôM.RSTö and ôP.BNDö will show up
if 0.3=P on OT.CF.
2. Press the /TARE
button. The meter shows the last previously stored 4-digit number (-1999
through 9999) with flashing 4th digit.
3. Press the /MAX
button to change the value of the flashing digit. If you continue to press
the /MAX button,
the flashing digit's value continues to change.
4. Press the /TARE
button to scroll to the next digit.
5. Press the MENU button to store your selection. "STRD"
momentarily displays, followed by "RST" (Reset).
USING
OUTPUT SCALE AND OFFSET ("OT.S.O")
Note: Refer to Table 6-1 for a summary list of menu configuration.
Output Scale and Offset ("OT.S.O") is not active unless your meter
has analog output capabilities. The menu will display whether analog output
is present or not. Output Scale and Offset ("OT.S.O") scales your
analog output to be equal to the meter's display and/or any engineering
units you require. You may scale the output for direct (4-20 mA, 0-10
V, etc) or reverse acting (20-4 mA, 10-0 V, etc).
1. Press
the MENU button until "OT.S.O" displays.
2. Press the /TARE
button. "RD 1" (Read 1) displays.
Note: This is your first point of display reading.
3. Press the /TARE
button again. The meter shows the last previously stored 4-digit number
(-1999 through 9999) with flashing 4th digit.
4. Press the /MAX
button to change the digits.
5. Press the /TARE
button to scroll to the next digit.
6. Press the MENU button to store your selection. "OUT.1"
(Output 1) displays.
Note: This starting analog signal corresponds to your Read 1 display.

button. Selected output displays.
If you select "O.2=V" for voltage, the maximum signal you may select
is 10.00 for an 0-10 Vdc signal output. If you select "O.2=C" for
current, the maximum signal you may select is 20.00.
8. Press the /MAX
button to enter the Output 1 signal selection. If you continue to press
the /MAX button,
the flashing digit's value continues to change.
9. Press the /TARE
button to scroll to the next digit.
10. Press the MENU button to store your selection. "RD
2" (Read 2) displays.
Note: This is your second point of display reading.
11. Press the /TARE
button. The meter shows last previously stored 4- digit number (-1999
through 9999) displays with flashing 4th digit.
12. Press the /MAX
button to change the value of the flashing digit. If you continue to press
the MAX button,
the flashing digit's value continues to change.
13. Press the /TARE
button to scroll to the next digit.
14. Press the MENU button to store your selection. The meter
shows "OUT.2" (Output 2).
Note: This analog signal should correspond to your Read 2 display.
15. Press the /TARE
button. The meter shows selected output.
NOTE: If you select "O.2=V" for voltage, the maximum signal
you may select is 10.00 for an 0-10 Vdc signal output.
If you select "O.2=C" for current, the maximum signal you may select
is 20.00 for a 0-20 or 4-20 mA dc signal output.
16. Press the /MAX
button to change the value of the flashing digit. If you continue to press
the /MAX button,
the flashing digit's value continues to change.
17. Press the /TARE
button to scroll to the next digit.

momentarily shows "STRD", followed by "LK.CF" (Lockout Configuration).
WARNING:
If the meter shows flashing values on RD 1 or RD 2, the value has overflowed.
Press the /MAX
button to start new values.
USING
