RE: Maybe no over voltage

Averaging meters tend to read low not high compared to a true RMS meter on a non sinusoidal waveform.

The power from the wall should be sinusoidal and averaging meters are usually calibrated to a sinusoidal waveform. So the difference between true RMS and averaging should be minimal.

But the meter could still be the problem if it is out of calibration.
