Analog Input Signal Calibration Settings
The functions in the following table
configure the signals for the analog input
terminals. Note that these settings do not
change the current/voltage or sink/source
characteristics – only the zero and span
(scaling) of the signals.
These parameters are already adjusted
before the shipment, and therefore it is
not recommended to do the adjustment at
the customer.
