Full wave voltage reading

Bob Engelhardt · 2019-07-08T14:47:50+00:00

If I measure a full wave voltage with a non true-RMS common variety DMM*, will it be off by a known factor, from the true RMS value? Or is there a rule of thumb about the error. E.g., the reading will be high by about 10%. Thanks, Bob * - Extech Ex320 if it matters

** With absolutely no evidence to the contrary, it is well good enough to cast very great doubt on an unsupported and improbable assertion for a known lying idiot.

** Standard DMMs, just like analogue types, read the average rectified value of a continuous wave scaled up by 1.11.

Perfectly accurately, with their working frequency ranges.
