VF3 is a Voltage Detector offers AC voltage automatic audible warning buzzer bright red voltage indicator in tip ultra-bright LED torch. The compact pen-style instrument to identify the presence of live AC voltages from 90 to 600V at 50 or 60Hz. Voltage is capacitively detected, signalled on the VF3 by the illumination of a bright red LED situated within the white nylon tip. It incorporates a torch and extended battery life is achieved by the use of a bright-white LED. The VF3 can be used for identifying the presence of ac voltage at socket outlets, switches, circuit breakers, fuses, luminaries, wires and cables. It can identify breaks in conductors by tracing along the cable from the source to the point where the indicator no longer illuminates; and also identify a blown fuse while in circuit.
