NI 5402/5406 Calibration Procedure
Adjusting the Calibration ADC
Complete this procedure to adjust the onboard calibration ADC of the
NI 5402/5406 that is used during self-calibration and external calibration.
You will characterize the gain and offset associated with this ADC.
1.
Connect the NI 5402/5406 CH 0 front panel connector to a DMM.
2.
Open an NI-FGEN external calibration session by calling the niFgen
Init Ext Cal VI.
3.
Initialize ADC calibration by calling niFgen Initialize Cal ADC
Calibration VI.
