NI 5450 Calibration Procedure

Optional Calibration
You can choose to skip the adjustment steps of the calibration procedure if
the measurement error is within the calibration test limits or the published
specifications during the first verification. If all of the measurement
errors determined during the first verification fall within the calibration
test limits, the device is warranted to meet or exceed its published
specifications for a full calibration interval. In this case, you can update
the calibration date, effectively resetting the calibration interval, without
actually performing an adjustment. Refer to the
section for
more information.
If all of the measurement errors determined during the first verification fall
within the published specifications, but not within the calibration test
limits, adjustment is also optional. However, you cannot update the
calibration date because the device will not necessarily operate within
the published specifications for an additional two years.
Note
Regardless of the results of the first verification, if you choose to perform an
adjustment, you must verify that the measurement error falls within the calibration test
limits at the end of the calibration procedure.
