Five Basic Digit/Display-setting Instructions
Rather than repeat the
S

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.
