NI 4070/4072 Calibration Procedure
14. Repeat step 13 for each of the remaining iterations shown in Table 3.
15. Output 500 mV at 30 Hz on the calibrator.
16. Call
niDMM_ConfigureMeasurement
with the following
parameters:
•
Function
=
NIDMM_VAL_AC_VOLTS_DCCOUPLED
•
Range
=
0.5
•
Resolution
=
500e–9
17. Call
niDMM_Read
. Verify that this measurement falls between the
limits listed in Table 18.
18. 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.
Table 3.
