Hide thumbs Also See for 9220:

Call the NI 9220 get C Series adjustment points function to obtain an array of

recommended calibration voltages for the NI 9220.

Set the calibrator to a reference value determined by the array of recommended

calibration voltages.

Set the calibrator to Operate mode (OPR).

Call and configure the NI 9220 adjustment function according to Table 5.

Physical Channel

cDAQMod8/aix

Set the calibrator to Standby mode (STBY).

Repeat steps d through g for each calibration voltage in the array.

Close the calibration session.

Disconnect the NI 9220 from the calibrator.

Repeat steps 1 through 4 for each channel on the NI 9220.

EEPROM Update

When an adjustment procedure is completed, the NI 9220 internal calibration memory

(EEPROM) is immediately updated.

If you do not want to perform an adjustment, you can update the calibration date and onboard

calibration temperature without making any adjustments by initializing an external calibration,

setting the C Series calibration temperature, and closing the external calibration.
