© National Instruments Corporation 49 NI 4065 Calibration Procedure
You have completed verifying DC current for the NI 4065. Select one of the
following options:
• If you want to continue verifying other modes, go to the Verifying AC
Current section.
• If you do not want to verify any additional modes and you are
performing a pre-adjustment verification, call the niDMM Close VI or
the
niDMM_close
function to close the session.
Verifying AC Current
To verify AC current for the NI 4065, complete the following steps:
1. Reset the calibrator.
2. Connect the NI 4065 and the Fluke 5700A/5720A calibrator using the
Fluke 5440 cable, as shown in Figure 7. Table 12 lists the cable
connections.
3. Call the niDMM Reset VI to reset the NI 4065 to a known state.
4. Set the current output on the calibrator to
NORM
and output 0 A. Allow
the calibrator to settle before proceeding.
