Calibration is not normally required after the FPDC is shipped. However, if
necessary, calibration is easily performed through the Controller module interface
with SCPI commands, requiring only a meter and a mating connector.

COPE
The factory calibration consists of setting the 4 outputs to nominal, that is +5VDC
= 5.000, etc. The following procedures can be used to reestablish this as
required.

ALIBRATION
Calibration can be done without load, therefore only a meter and a specially
configured mating connector is required, made up as follows:
(Note: these Test Connectors are used during performance verification as well).

OWER
In all cases, there is a wire for each of the 4 outputs and their corresponding
returns. These should be two to three inches in length and have the bare ends
soldered, (tinned) for convenient connection to the DMM. These are labeled as
Stub in the Type column.
