Extech EX65x True RMS 600A Clamp Meters

Extech EX65x True RMS 600A Clamp Meters provide highly accurate readings when measuring distorted or noisy waveforms. False readings caused by ghost voltages are eliminated by a low impedance (LoZ) mode. These meters feature a 1.18" (30mm) jaw size that accommodates conductors up to 350MCM. Functions include µA for HVAC flame rod current measurements, data hold, minimum/maximum, and relative. A 6000 count backlit LCD offers an auto power-off to help conserve battery life. The EX655 model also features a low pass filter (LPF) which attenuates high frequencies to decrease noise for more accurate readings, and an inrush mode to capture current surges during motor startup.
