caling feature allows it to be programmed using only the
ENTER
button. The general procedure is to press the
ENTER
button to accept a
flashing display or to wait for the display to scroll and press
ENTER
when the
desired display appears.
For instance when the
ENTER
button is pressed, the meter scrolls through the stan-
dard programming routine titles:
[ALIb
,
TYPE
,
F or [

Alars
.
It will also scroll the
optional programming routine title:
OvtPvt
if the meter contains the isolated 4-20
mA Output Option. To enter a programming routine, press
ENTER
when the meter
displays the desired programming routine title.
The following flow chart overviews the meter programming routines.
There are 5 basic programming instructions
1. If the flashing display is OK, press
ENTER
before it stops flashing to accept it.
2. If the flashing display is not OK, (or if
ENTER
was not pressed in time to
accept it), wait for first digit to flash.
3. If a flashing digit is OK press
ENTER
before it starts to scroll to accept it.
4. If a flashing digit is not OK, (or if
ENTER
was not pressed in time to accept it),
wait for the digit to scroll, and press
ENTER
when OK.
5. Digits will scroll until
ENTER
is pressed. When a digit is accepted by pressing
ENTER
, the next digit flashes.
For best results, allow the meter to warm up for at least
30 minutes before calibrating.
