6.
Repeat step 5 for each of the remaining iterations shown in Table 14.
7.
Refer to Table 15 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 15 for the current iteration.
b.
Call
niDMM_CalAdjustACFilter
with
Mode
set to
NIDMM_VAL_AC_VOLTS
and the remaining parameters as shown
in Table 15 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
.
