Klein Tools Electronic AC/ DC Voltage Tester 12 - 600V Orange/Black. It measures AC/DC voltages up to 600V. The ET60 does NOT require batteries; it is powered by the applied voltage. Specifications for Klein Tools Electronic AC/ DC Voltage Tester: Manufacturer: Klein Tools Voltage: 600 volts Color: Orange/Black Features of Klein Tools Electronic AC/ DC Voltage Tester Voltage Tester for AC/DC voltage from 12-600V at nine useful levels aligned with commonly used voltages. Uses standard replaceable multimeter test leads for versatility. CAT IV 600V modern solid-state design for safety. Easy to use bright LED display clearly reports the voltage present in the circuit being tested. Integrated test-lead holders are used for lead storage or for holding the probes correctly spaced for insertion into tamper-resistant US-style outlets. Inherent low input impedance reduces the possibility of falsely reading ghost or stray voltages on non-energized circuits. Batteries not required as tester is powered by the applied voltage in the circuit being tested.
