8.5 Test the expansion cards in the Maintenance menu
8.5.1 Test the output card
In the TEST/MAINT menu, every output current can be set to certain values for testing
reasons. If necessary, each output can be adjusted as well. Additionally, the current state
of the outputs can be requested.
The output current can be set to certain values and then be adjusted with an offset and a
factor.
To set these two parameters:
1. Set the SET OFFSET value to “0” and the SET FACTOR value to “1”.
2. Set the output current (CURRENT OUT) to “4 mA” and then only adjust the SET
OFFSET value until the output current is really 4 mA.
3. Set the output current (CURRENT OUT) value to “20 mA”, then adjust the factor until
the output current is really 20 mA and cross-check the 4 mA.
4. Repeat the steps 1-3 until the output precision reaches a desired value.
