RM-26999 Calibration Procedure
4
ni.com/calibration
Make all connections as shown in diagrams.
Use shielded copper wire for all cable connections to the DUT.
Use twisted-pair wires to eliminate noise and thermal offsets.
Ensure that the PXI/PXI Express chassis fan speed is set to HIGH, that the fan
filters are clean, and that the empty slots contain filler panels. For more
information, refer to the Maintain Forced-Air Cooling Note to Users document
If a DUT fails reverification after adjustment, ensure that the Test Conditions
have been met before returning the DUT to NI.
Allow the calibrator and DMM to settle fully before taking any measurements. NI
recommends a settling time of 10 seconds. Consult the calibrator and DMM user
documentation for more information.
Allow 2 minutes for the thermal EMF to stabilize after changing connections to
the calibrator, DMM, or DUT.
