SCXI-1102/B/C Calibration Procedure
4.
Set the SCXI-1102/B/C to a gain value of 1 or 100 using the DAQmx
Setup SCXI Calibration VI.
5.
Set the calibrator to the desired voltage for the gain value you set in the
previous step. Refer to Table 3 or 4 for appropriate voltage set points.
6.
Wait for the settling time to elapse and then record the measured output
from the DMM. Refer to Table 5 for the settling time of the
SCXI-1102/B/C.
