SECTION 4
Input Trimming
Figure 4.9. gives an overview of the Input Trimming menu.
Input trimming increases the measurement accuracy of the parameter you are trimming by matching
the reading of its actual input to its scaling. The SPA
2
offers the use of a factory-configured trimming
feature (“FCTRY TRIM“) or user-set, one-point or two-point (“USER 1PNT” OR “USER 2PNT”)
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 the “TRIM MODE” appears, press
SELECT
.
2. “FCTRY TRIM” is displayed, press
SELECT.
This takes you to the “EXIT TRIM” screen.
3. To exit, press
SELECT
.
To input user-specific trim values, perform the following steps:
1. At the “TRIM INPUT” display, press
SELECT
. When “TRIM MODE” appears, press
SELECT
again. Use the
UP
and
DOWN
buttons to reach the user-set trimming menus. Press
SELECT
once the desired parameter is displayed– “USER 1PNT” or “USER 2PNT”.
2. “TRIM ZERO” appears. To program, press
SELECT
. Your present zero scaling value is
shown and prompts you to “APPLY” your value. Press
SELECT,
once your value is present
and flashing at the appropriate input terminals, press
SELECT
again
.
If you selected “USER
1PNT” trimming, “EXIT TRIM” appears. Press
SELECT
to reach the “CONFG AOUT” menu
(or “CONFG ALARM” menu if the -AO option is not enabled). Proceed to Step 3 for “USER
2PNT” trimming.
3. If you selected “USER 2PNT” trimming, repeat the instructions in Step 2 for the “TRIM FULL”
setting. Press
SELECT
when “EXIT TRIM” is displayed to reach the “CONFG AOUT” menu
(or “CONFG ALARM” menu if the -AO option is not enabled).
Note:
Trim only the zero and full values entered in the “SCALE INPUT” menu through the front
panel pushbuttons. To trim values other than those specified in the “SCALE INPUT” menu, you
must use the PC Configuration Software program.
