NOTE: The PEAK function displays the maximum value of the input waveform. The sampling time for the PEAK function is

39μs (50Hz) or 33μs (60Hz). The HOLD, MAX, or MIN function displays the true RMS value.

The tester has an auto-power-off function. The tester will turn the power off after power is turned on for 15 minutes.
