DAQM907A Analog Output Verification (Optional)

This procedure is used to check the calibration of the analog outputs (Channel 04
and 05) on the DAQM907A. Perform the module auto-calibration before starting
this test. When performing module auto-calibration, the analog outputs and
sense inputs will be calibrated to the DMM in the DAQ970A/DAQ973A.
