About This Instrument
The DM 321T is a 3½-digit True-RMS digital multimeter for general electrical and electronic test work. It is a manual-ranging instrument (not auto-ranging), measuring AC/DC voltage, AC/DC current, resistance, and capacitance, alongside continuity test, diode test, and transistor (hFE) test. Supplied with a protective holster. True-RMS measurement gives accurate readings on non-sinusoidal AC waveforms — useful when working on circuits with switching loads or harmonics. DC voltage up to 1000 V; DC current up to 20 A. Auto power-off and data hold standard. Dimensions: 175 × 93 × 55 mm. Weight: approx. 400 g (incl. battery).
