Alternative to Adjustment Procedures
If your device passes all verification procedures successfully and you want to skip updating
the calibration constants, you can update solely the calibration date by completing the
following steps.
Note NI recommends following all adjustment procedures in order to update the
calibration constants and renew the device calibration interval.
1. Call one of the following:
•
niDCPower Initialize External Calibration VI
•
niDCPower_InitExtCal
function
2. Call one of the following, specifying Commit in calibration close action :
• niDCPower Close External Calibration VI
• niDCPower_CloseExtCal function
Reverification
Repeat the Verification section to determine the as-left status of the device.
Note If no as-left test limits are specified in a procedure, reuse the as-found test
limits.
Note If any test fails reverification after performing an adjustment, verify that you
have met the Test Conditions before returning your device to NI. Refer to the
Worldwide Support and Services section for information about support resources or
service requests.

Setting the Calibration Due Date
Use either Measurement Automation Explorer (MAX) or NI System Configuration API to set
a calibration due date for the device or to clear the calibration due date. NI suggests a
minimum calibration due date of the date of external calibration plus the external calibration
interval for the device.
1.
In MAX, navigate to the External Calibration section of the Settings tab to update the
Calibration Due Date entry.
2. Alternatively, use the Update Calibration VI in the NI System Configuration API to set
the calibration due date for either a specific date or an interval in months.
