values as you complete the following steps:
a.
On the calibrator, output the value listed in the Calibrator Output
column in Table 13 for the current iteration.
column in Table 13 for the current iteration.
b.
Call
niDMM_CalAdjustACFilter
with Mode set to
NIDMM_VAL_AC_VOLTS
and the remaining parameters as shown
in Table 13 for the current iteration.
Note
The Session parameter remains the same for all instances of this function.
c.
Call
niDMM_CalAdjustACFilter
again, changing Mode to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
