The Megger VF3 voltage detector is a compact pen-style instrument to identify the presence of live AC voltages from 90 V to 600 V at 50 or 60 Hz. Voltage is capacitively detected, signalled on the VF3 by the illumination of a bright red LED situated within the white nylon tip. The VF3 has the additional feature of an audible warning device actuated simultaneously to the red LED.
The VF3 incorporates a torch. 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.
