1ms Peak Hold

You can use this Meter to analyze components such as power distribution trans-

formers and power factor correction capacitors. The additional features allow the

measurement of the half-cycle peak current by using the I ms peak hold feature.

This allows the determination of the crest factor:

Crest factor = Peak value/True rms value

1 ) Press PEAK button for more than 1 second to toggle 1 ms peak hold mode

ON/OFF.

2) Press PEAK button momentarily to select PEAK+ measurement after entering

the peak mode. The display shows "DH MAX" to indicate the PEAK +. See

Figure 16.
