No, this meter does not give true RMS readings. These meters read the peak-to-peak AC voltage and multiply by .35 or 35 percent. This method is acceptable for purely sinusoidal waveforms at a constant frequency, ie Household hydro at 120VAC at 60 hz. Any other waveform, such as Square, triangle, etc. or varying frequency requires a much more expensive meter.
