Key Concepts

Form Factor (Conversion Factor)

The form factor is the ratio between the RMS value and the average (rectified) value of a waveform. For a sine wave, this factor allows the analogue multimeter to convert the averaged reading into the RMS reading, which is what is usually desired in AC voltage measurements.

Analogue Multimeter AC Measurement

Analogue multimeters measuring AC voltage typically operate by rectifying the AC signal and then reading its average value. They are calibrated using a predetermined conversion factor (or form factor) so that the displayed reading corresponds to the effective RMS voltage for a sinusoidal waveform.

Average (Rectified) Voltage

The average voltage for an AC waveform, particularly when considering its absolute value after rectification, is the mean of the waveform over a cycle. In many analog meters, the measured value is the average of the rectified waveform, which then needs to be converted to an RMS value when the waveform is sinusoidal.

Root Mean Square (RMS) Voltage

RMS voltage is a measure used to express the effective value of an alternating current or voltage. It is defined as the square root of the average of the squares of the instantaneous values over one cycle. For sinusoidal signals, the RMS value represents the equivalent DC value in terms of power delivery.
