4.
Call the niDMM Config Measurement VI and select the
Resolution in Digits
instance.
5.
Call the niDMM Configure Frequency Voltage Range VI with
Voltage Range
set to
5
.
6.
Configure the external source to generate a pulse train with a voltage of 0
to
5 V and a duty
cycle of 50%
The frequency should be set to 1 Hz.
7.
Call the niDMM Read VI.
8.
Repeat steps 6 and 7 with the following modification: Change the frequency to 20 kHz.
9.
Repeat steps 6 and 7 with the following modification: Change the frequency to 500 kHz.
