NI 4071 7½-Digit FlexDMM Calibration Procedure
75. Reset the calibrator for safety reasons.
You have completed verifying the DC voltage of the NI 4071. Select one of the following
options:
•
If you want to continue verifying other modes, go to the
section.
•
If you do
not
want to verify other modes
and
you are performing a
post-adjustment

Completing the Adjustment Procedures
section.
•
If you do
not
want to verify any additional modes
and
you are performing a
pre-adjustment
verification, call the niDMM Close VI to close the session.
Verifying AC Voltage
To verify the AC voltage of the NI 4071, complete the following steps:
1.
Reset the calibrator.
2.
Connect the NI 4071 and the Fluke 5720A calibrator using the Fluke 5440 cable, as shown
in Figure 1. Table 2 lists the cable connections.
3.
Generate 4.5 mV at 1 kHz on the calibrator.
4.
Call the niDMM Reset VI to reset the NI 4071 to a known state.
5.
Call the niDMM Configure Auto Zero VI.
