SETUP AND PROGRAMMING
Power, Signal, External Functions & Options Connections
Disconnect power to the meter before making any connections.
Do not connect power or earth ground to any unused or CM terminals.
Observe polarity for DC powered Meters. Applying voltage with
reverse polarity may damage the instrument.
Connecting 230VAC to a meter specified to accept 115VAC or con-
necting AC power to a meter specified to accept DC power will result
in damage to the instrument as well as endanger personnel. Keep pri-
mary wires separated from signal cables.
Notice:
•Primary voltages must not be accessible to the user.
•Primary wires must be installed in accordance to the applicable
standards.

4-20 mA Output
The 4-20 mA output from the meter can either be powered from the
meter’s internal transmitter power supply, (if it is not being used to
power the input loop), or by an external power supply as the follow-
ing diagrams illustrate:
Figure 10: Meter Powering 4-20 mA Output Loop
Figure 11: External Power Supply Powering 4-20 mA
Output Loop
If the output loop is powered by an external supply, the loop
power supply must be turned on before the meter is turned
on. Otherwise, the output loop signal may be incorrect.

Programming
Overview
The meter is programmed using the ENTER button and three jumper
arrays.The ENTER button controls the meter’s
S ingle B utton S caling
(SBS) feature that allows the meter to be completely programmed
using just one button.The jumper arrays are used for programming
the input signal, lockout, relays acknowledge enable and relays fail-
safe operation.
Single Button Scaling (SBS)
S ingle B utton S caling is a technique that allows the meter to be com-
pletely programmed using just the ENTER button.The general
method behind
(SBS) is to push ENTER when the meter reads the
desired value.This value may be a menu title, the entire display or
just a single digit. If the meter is not reading the desired value wait
and the value will change. When the meter finally reads the desired
display push ENTER to accept it.
When the meter is first powered up, it will read a random number.
Pushing ENTER will cause the meter to scroll through the following
menu titles (if the Lockout Jumper is not installed):

Five Basic Digit/Display-setting Instructions
Rather than repeat the S ingle B utton S caling (SBS ) technique for
every function it is used in, it will be detailed here and the user can
refer to it when necessary.
The
S ingle B utton S caling technique is used to program all the
meter's functions that require numbers to be entered. For instance,
calibration and scaling values, Low-flow Cutoff values, alarm set and
reset points, 4 and 20 mA output values are set using
(SBS).
1. If the flashing display is OK, push ENTER before it stops flashing
to accept it. (Whenever a new value is to be programmed or Most
Significant Digit has been accepted the entire display flashes, if
this is the desired value, press ENTER before it stops flashing to
accept it.)
2. If the flashing display is not OK, (or if ENTER was not pushed in
time to accept it), wait for Least Significant Digit (LSD) to flash.
3. If a flashing digit is OK, push ENTER before it starts to scroll to
accept it.
4. If a flashing digit is not OK, (or if ENTER was not pushed in time
to accept it), wait for the digit to scroll and push ENTER when OK.
5. Digits will scroll until ENTER is pushed. When a digit is accepted
by pushing ENTER, the next digit to the left flashes.
Basic Meter Programming
Overview
There are four steps for programming the basic meter functions:
1. Select Input
2. Perform Initial Calibration if Needed
3. Select Calibration Method
4. Calibrate or Scale the Meter
Programmed Parameter Values
To simplify programming, the user should write down the desired
programming values prior to attempting to program the meter.The
form located at the back of this manual provides a convenient method
to record the user settings.
