Overview

KM-4000 is a 6000-count digital clamp meter with auto range, large LCD, True RMS, autoscale memory, and NCV functions. They conform to CAT III 1000V/ CAT IV 600V safety rating and certified by CE/ETL. KM-4000 has LoZ mode for eliminating 'ghost 'voltage, LPF ACV function for measuring INV and VFD voltage, and Inrush current mode for capturing transient current. The KM-4000 also features high-precision temperature measurement with 0.1 °C resolution, and can be equipped with a flexible current probe to extend the AC current measurement range to 3000A.
