A measured voltage is ~160V, but software shows 230V (True RMS measurement)
Last Updated 10 months ago

If the monitoring software shows 230V on the output, but you have measured something dramatically lower, possibly you are using a wrong tool.

To properly measure the voltage of a UPS without pure sine wave output, you need a special meter with true RMS. UPSs with Pulse Width Modulated output (square wave) will show proper 230VAC in the software, but measured voltage might be lower (i.e. ~160VAC). This value is expected if basic multimeter is used.
