Analysis of measuring Non-sinusoidal AC Voltage by Multimeter

The rectifier instrument composed of the magnetoelectric system measuring mechanism of the multimeter and the rectifying circuit indicates the average value of the AC voltage. In engineering technology, it is usually necessary to measure the effective value of AC voltage or current. In order to meet this need, the scale of AC voltage of multimeter is calibrated according to the effective value of sinusoidal AC voltage.
