Voltage Indicator 40-440VAC

• Unique sensor locates breaks along live, insulated wires and power cords, checks for energized AC circuits, distinguishes polarity and detects leaks in underground devices
• Powered by two 1.5V alkaline batteries (Industry No. 357), included
• Audible and visual indication
• Ideal for use by all electricians
• Tests for voltage without contact in electric lines from 40V to 440V AC
To test for voltage on lines, cables, plugs, sockets or switches, place indicator close to object. Press button. If voltage is present, LED indicator will light continuously, and an audible indicator will be heard.To determine ground to earth, place indicator near metal on grounded appliance. Press button. If ground is disconnected, LED indicator will light continuously and an audible indicator will be heard.When checking polarity, LED indicator shines brightly and an audible indicator is heard to quickly identify hot wire.
