Inductive Measuring Mode of GVDA New arrive Voltage detector tester pen GD110A
When the probe is placed close to the AC voltage, the buzzer sounds and the voltage level will show on the display. The higher the voltage, the more rapid the buzzer sounds. Likewise, "HI" on the display indicates high voltage, "U" indicates low voltage. With this function, you can differentiate between Null and Live wires, or find the breakpoint of the wire.
