Complete Calibration
Performing a complete calibration is the recommended way to guarantee that the
NI 5122/5124/5142 will meet or exceed its published specifications for a two-year calibration
interval. At the end of the complete calibration procedure, you verify that the measurement error
falls within the calibration test limits. Figure 1 shows the programming flow for complete
calibration.

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 guaranteed 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.
