Use the following procedure to calibrate the analog outputs if a meter
reading in the “

Analog Output Testing

” procedure differed by more than

one percent or after replacing the optional I/O expansion board.

Equipment Required:

Multimeter

Connect a meter to the channel to be adjusted and set to voltage or
current as appropriate.
