5.
Refer to Table 9 for the appropriate parameter values as you complete
the following steps:
a.
Output 0 V on the calibrator.
b.
Call
niDMM_CalAdjustOffset
with
Mode
set to
NIDMM_VAL_AC_VOLTS
and the remaining parameters as shown
in Table 9 for the current iteration.
c.
Call
niDMM_CalAdjustOffset
again, changing
Mode
to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
6.
Repeat step 5 for each of the remaining iterations shown in Table 9.
7.
Refer to Table 10 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 10 for the current iteration.
b.
Call
niDMM_CalAdjustACFilter
with
Mode
set to
NIDMM_VAL_AC_VOLTS
and the remaining parameters as shown
in Table 10 for the current iteration.
