Klein Tools MM420 Multimeter is an auto-ranging, true root mean square (TRMS) multimeter that measures AC/DC voltage, AC/DC current, and resistance. It can also measure temperature, capacitance, frequency, duty-cycle, and test diodes and continuity. Klein Tools Test and Measurement product line was exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters and electrical testers loaded with innovative, time-saving features.Multimeter with automatic ranging true root mean square (TRMS) technology for increased accuracyMeasures up to 600V AC/DC voltage, 10A AC/DC current and 50 MOhms resistance, continuity, temperature, capacitance, frequency, duty-cycle, and test diodesLead Alert protection with LED illumination for lead placement and an easy-to-view backlit displayLow battery indicator and easily accessible battery and fuse compartmentDurable meter built to withstand a 6.6-Foot (2 m) dropIncludes Multimeter, Test Leads with CAT III/CAT IV Safety Caps, Thermocouple, Instructions, 2 x AAA BatteriesCAT III 600V safety ratingFor use in basic and controlled electromagnetic environments such as residential, business and light-industrial locations
