Digital Multimeter, TRMS Auto-Ranging, 1000V, Temp, Low Impedance. Multimeter with automatic ranging true root mean square (TRMS) technology for increased accuracy. Tester measures up to 1000V AC/DC voltage, 10A AC/DC current and 60 MOhms resistance plus temperature, capacitance, frequency, low impedance (LoZ), duty-cycle, test diodes and continuity. High visibility, reverse contrast display with optical sensor to automatically optimize viewability in dark or bright ambient lighting. Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages. Low battery indicator and easily accessible battery and fuse compartment. Tough meter built to withstand a 6.6-Foot (2 m) drop and is rated IP42. Includes carrying pouch, test leads, thermocouple with adapter, and batteries. CAT IV 600V Safety Rating. For use in basic and controlled electromagnetic environments such as residential, business and light-industrial locations
