Figure 4-68 DC Measurement Setup Screen
Please see section 4.4 for the calculation formula of DC value. If the test signals contain
AC and DC
portions, the frequency of AC will determine the sampling frequency of
digital-analog converter. If there is only DC, the sampling frequency will use AC LINE
INPUT frequency to determine the sampling frequency. When doing DC measurement, it
is suggested to use digital low pass filter to make the DC measured value more stable and
accurate without compromising the AC measurement accuracy conditions. The setting of
measurement range is determined based on the entire waveform signal amplitude. If the
AC signal is much larger than the DC signal, the DC measurement accuracy will be affected
caused by low resolution.
Following is the setting procedure:
1. Press SETUP to select DC and the DC indicator is on.
