NI 9222/9223 Calibration Procedure
3.
Adjust the NI 9222/9223.
a.
Initialize a calibration session on the NI 9222/9223. The default password is
NI
.
b.
Input the external temperature in degrees Celsius.
c.
Call the NI 9222/9223 get C Series adjustment points function to obtain an array of
recommended calibration voltages for the NI 9222/9223.
d.
Set the calibrator to a reference value determined by the array of recommended
calibration voltages.
e.
Set the calibrator to Operate mode (OPR).
f.
Call and configure the NI 9222/9223 adjustment function according to Table 6.
g.
Set the calibrator to Standby mode (STBY).
h.
Repeat steps d through g for each calibration voltage in the array.
i.
Close the calibration session.
4.
Disconnect the NI 9222/9223 from the calibrator.
5.
Repeat steps 1 through 4 for each channel on the NI 9222/9223.
EEPROM Update
When an adjustment procedure is completed, the NI 9222/9223 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.
Reverification
Repeat the
section to determine the As-Left status of the device.
Note
If any test fails Reverification after performing an adjustment, verify that you
before returning your device to NI. Refer to
for assistance in returning the device to NI.
