appropriate binding posts on the calibrator, as described in Figure 3
and Table 1.
3. Refer to Table 8 for the appropriate calibrator output and parameter
values as you complete the following steps:
a. On the calibrator, output the value listed under Calibrator Output
in Table 8 for the current iteration.
b. Call
niDMM_CalAdjustGain
with Mode set to
NIDMM_VAL_AC_VOLTS
. Set the remaining parameters as shown
in Table 8 for the current iteration.
c. Call
niDMM_CalAdjustGain
again, changing Mode to
NIDMM_VAL_AC_VOLTS_DCCOUPLED
.
4. Repeat step 3 for each of the remaining iterations listed in Table 8.
