1 ms peak hold
This function allows the measurement of peak voltage for
analysis of components such as power distribution
transformers and power factor correction capacitors. The
peak voltage obtained can be used to determine the crest
factor.
Crest factor = Peak value/True- rms value
To measure the half- cycle peak voltage:
1
Press
for more than one second to toggle 1 ms peak
hold mode on or off.
2
Press
to show the peak
+
or peak– value after
activating the peak mode. The
DH MAX
annunciator
indicates the peak+ value while the
DH MIN
annunciator
indicates the peak– value. See
Figure 3- 10
on page 64.

If the reading is
OL
, press
to change the
measurement range and restart the peak value
measurement.
