True RMS Digital MultiMeter

True RMS digital multimeters directly calculate the root mean square (RMS) value of AC signals using dedicated chips, enabling accurate measurement of non-sinusoidal waveforms. They are used to detect the voltage and current of nonlinear loads such as inverters and dimming circuits, directly reflecting actual power in applications like motor debugging and electrical maintenance.
Selection
When selecting, ensure that the AC frequency response range covers the signal being measured, and check for the true RMS (TRMS) marking. Consider a safety rating of CAT II or higher based on the measurement environment, with a basic accuracy of 0.5% being sufficient. Choose a handheld type for portable situations and a benchtop type for fixed workstations. Pay attention to the probe's protection rating and input impedance matching.
