Verification
The following performance verification procedure describes the sequence of operation and
provides test points required to verify the NI 9266. The verification procedure assumes that
adequate traceable uncertainties are available for the calibration references.
Accuracy Verification
Complete the following procedure to determine the As-Found status of the NI 9266.
1. Set the DMM to Standby mode (STBY) and disable the output of the bench-top power
supply.
2. Connect the NI 9266 to the bench-top power supply and the DMM as shown in the
