The design principle is that the voltage and current sampling parts do not use transformers, but instead use resistors for direct sampling, ensuring that the original signal is processed without distortion. The internal sampling and calculation of the instrument adopt the root mean square calculation method to ensure the accuracy of the measured data.
Suitable for measuring various waveforms with sinusoidal half waves and other similar DC components of current. Under AC testing conditions, it can test resistive full waves, distorted waves, half waves formed by diodes, waveforms formed by single and bidirectional thyristors, symmetrical and asymmetrical square waves, triangular waves, saw tooth waves, and other special waveforms. It is suitable for testing vacuum cleaners, electric heating appliances, small appliances, and other gear shifting devices that pass through diodes or thyristors.
