© National Instruments Corporation 19 NI 4070/4072 Calibration Procedure
21. Refer to Table 4 for the appropriate calibrator outputs and parameter
values as you complete the following steps:
a. On the calibrator, output the value listed in the Calibrator Output
column in Table 4 for the current iteration.
b. Call
niDMM_ConfigureMeasurement with Mode set to
NIDMM_VAL_AC_VOLTS and the remaining parameters as shown
in Table 4 for the current iteration.
c. Call
niDMM_Read. Verify that this measurement falls between the
limits listed in Table 16.
d. Call
niDMM_ConfigureMeasurement again, changing Mode to
NIDMM_VAL_AC_VOLTS_DCCOUPLED.
e. Call
niDMM_Read. Verify that this measurement falls between the
limits listed in Table 16.
22. Output 50 V at 30 Hz on the calibrator.
