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:

1 Press Shift/Peak for more than 1 second to toggle 1 ms peak hold
2 Press Hold/Max Min to switch between maximum and minimum peak
3 Press Shift/Peak for more than 1 second to exit the mode.
