Data record instr.digital-multimeter.true-rms

Verified 2026-10-27 Confidence: High

A true-RMS multimeter computes the effective heating value of an alternating waveform and reads correctly on distorted waveforms such as the current drawn by variable-speed drives and electronic loads, whereas an average-responding meter is scaled to read correctly only on a pure sine wave and reads low or high on a distorted one.
