NI 5450 Calibration Procedure
Adjustment
If the NI 5152/5153/5154 successfully passed each of the verification
procedures within the calibration test limits, then an adjustment is
recommended but not required to warrant the published specifications for
the next two years. If the digitizer was not within the calibration test limits
for each of the verification procedures, you can perform the adjustment
procedure to improve the accuracy of the digitizer. Refer to
to determine which procedures to perform.
An adjustment is required only once every two years. Following the
adjustment procedure automatically updates the calibration date and
temperature in the EEPROM of the digitizer.
Note
If the digitizer passed the entire verification procedure within the calibration test
limits and you do not want to perform an adjustment, you can update the calibration date
and onboard calibration temperature without making any adjustments by calling
only
niScope Cal Start and niScope Cal End VIs.
