MODEL 54 C SECTION 3
PROGRAMING THE ANALYZER
This section describes the options available for configuration of the
outputs. The designation “O1” refers to output 1. The designation “O2”
refers to output 2.
1. From the program menu . . . with the cursor on “Outputs” press
Enter (F4).
2.
* Enabling the hold feature will give the user the option of activat-
ing the hold function during the calibration sequence. The 20-min
timeout selection also offers this option, but removes the hold func-
tion automatically after 20 minutes.
**If the output 1 range is changed, be sure to rerange output 1 as
described in Section 3.2 .
*** Dampens the response of the signal output. This option is useful
to minimize the effect of a noisy reading. The number entered is
the sampling time (in seconds) for an averaged output.
NOTE
Enter (F4) must be pressed after a cursor value is changed
for the analyzer to update.
Pressing More (F3) allows the configuration of hold and fault function.
3.
If fixed hold selected, then output 1 fixed hold must be set at
desired held output between 0-22 mA. Fixed hold is factory set at
21.00 mA and fault conditions are factory set at 22.00 mA.
Pressing More (F3) allows the selection of output 2 options.
