Input Trimming
Figure 4.5 gives an overview of the Input Trimming menu.
Input trimming increases the measurement accuracy of your instrument by matching the reading
of its actual input to its scaling. The STA
offers the use of a factory-configured trimming feature
(“FCTRY TRIM”) or user-set, one-point or two-point (“USER 1 PNT” OR “USER 2 PNT”) trimming.
Unit default is “FCTRY TRIM”. If another trimming selection had been made and you wish to
return to the “FCTRY TRIM” feature follow the instructions below.
1. Press
SELECT
at the “TRIM INPUT” screen. Once “TRIM MODE” appears, press
SELECT
.
2. Use the
UP
or
DOWN
buttons to reach the “FCTRY TRIM” display, and then press
SELECT.
This takes you to the “EXIT TRIM” screen.
3. To exit, press
SELECT
. Proceed to the “ALARM CONFG” menu
To input user-specific trim values, perform the following steps: Refer to Figure 2.1 for set up and
Table 2.1 for necessary equipment.
1. At the “TRIM INPUT” display, press
SELECT
. When “TRIM MODE” appears, press
SELECT
again. Use the
UP
or
DOWN
buttons to reach the user-set trimming menus.
Press
SELECT
once the desired parameter is displayed– “USER 1 PNT” or “USER 2
PNT”.
2. “RESET TRIM ” appears, press
SELECT
. Use the
UP
or
DOWN
buttons to the desired
parameter, “RESET NO?” or “RESET YES?”. Select “RESET YES?” to clear previous
trimming adjustment values, or “RESET NO?” to keep them.
Resetting will keep trimming enabled, however no adjustment will be made to the input
value. If the input is about to be trimmed, then this step is unnecessary
3. “TRIM ZERO” appears. To program, press
SELECT
. Your present zero-scale trimming
value is shown, use the
UP
and
DOWN
buttons to change value, to “APPLY” your value;
press
SELECT.
Once your value is present and flashing, press
SELECT
again
.
If you
selected “USER 1 PNT” trimming, “EXIT TRIM” appears. Press
SELECT
to reach the
“CONFG ALARM” menu. Proceed to Step 4 for “USER 2 PNT” trimming.
4. If you selected “USER 2 PNT” trimming, repeat the instructions in Step 2 for the “TRIM
FULL” setting. Press
SELECT
when “EXIT TRIM” is displayed to reach the “CONFG
ALARM” menu.
Note:
In the event that captured values for TRIM ZERO and/or TRIM FULL are incorrect,
ERROR TRIM will be displayed after values are applied. Press SELECT to exit ERROR TRIM,
which will prompt EXIT TRIM. Use the UP or
DOWN
buttons to return to TRIM ZERO and/or
TRIM FULL to make changes needed.
