The PEAK function is accessible when measuring AC Voltage or Current. It captures and
displays the highest positive peak and the highest negative peak of the AC waveform.
1. Press and hold the PEAK button until “Peak MAX” appears on the LCD display.
The meter will display the highest reading and will update the reading when
a higher positive peak occurs.
2. To view highest negative peak, press the PEAK button for approximately one
second. “Peak MIN” will appear on the LCD display and the meter will display
and hold the highest reading. The meter will update the reading when a higher
negative peak occurs.
3. Press the PEAK button for approximately one second to switch between Peak
MAX and Peak MIN readings.
4. Press and hold the PEAK button to exit PEAK and return to normal operation.
