4.
Repeat step 3 for each of the remaining iterations listed in Table 13.
5.
Refer to Table 14 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 14 for the current iteration.
c.
Call
niDMM_CalAdjustOffset
again, changing
Mode
to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
