NI 4071 7½-Digit FlexDMM Calibration Procedure
Adjusting AC Voltage (AC- and DC-Coupled) Modes
Note
If you do not use the AC voltage modes for any measurements, or the
accuracy of these modes is irrelevant, you can skip this section and go directly to the
To adjust 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.
Refer to Table 17 for the appropriate calibrator output and parameter values as you
complete the following steps:
a.
On the calibrator, generate the value listed under Calibrator Output in Table 17 for the
current iteration.
b.
Call the niDMM Cal Adjust Gain VI with
Mode
set to
NIDMM_VAL_AC_VOLTS
. Set
the remaining parameters as shown in Table 17 for the current iteration.
c.
Call the niDMM Cal Adjust Gain VI again, changing
Mode
to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
