Description

M-271+ AC/DC Digital Clamp Meter with True RMS, 2000A Current Measurement

The MULTImic M-271+ AC/DC Digital Clamp Meter is a multifunctional measuring instrument designed for AC and DC current measurements up to 2000 A. It features a 55 mm diameter teardrop-shaped clamp opening and True RMS measurement for AC current and AC voltage. Additional functions include AC/DC voltage, frequency, resistance, diode testing, and continuity checking. The meter also features automatic zero adjustment for DC current offset, data hold, and automatic power-off for convenient electrical testing and maintenance.
