22. Output 50 V at 30 Hz on the calibrator.
23. Call
niDMM_ConfigureMeasurement
with the following
parameters:
•
Function
=
NIDMM_VAL_AC_VOLTS_DCCOUPLED
•
Range
=
50
•
Resolution
=
50e–6
24. Call
niDMM_Read
. Verify that this measurement falls between the
limits listed in Table 12.
25. Refer to Table 5 for the appropriate calibrator outputs and parameter
values as you complete the following steps:
a.
On the calibrator, output the value listed under Calibrator Output
in Table 5 for the current iteration.
b.
Call
niDMM_ConfigureMeasurement
with
Mode
set to
NIDMM_VAL_AC_VOLTS
and the remaining parameters as shown
in Table 5 for the current iteration.
c.
Call
niDMM_Read
. Verify that this measurement falls between the
limits listed in Table 12.
d.
Call
niDMM_ConfigureMeasurement
again, changing
Mode
to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
e.
Call
niDMM_Read
. Verify that this measurement falls between the
