The voltage test pen is suitable for the detection and use of AC & DC static eliminator and static electricity generating equipment, non-contact induction lighting display mode, and the operation is very safe and convenient. There is no need to touch the emitter (ion needle) of the electrostatic device during operation. As long as the distance is measured according to the working voltage of different devices, the display light (red light or not) at the front of the pen tip (white area) can be used to judge whether the high voltage output of the electrostatic device is normal or not. . High voltage is the low voltage required for equipment to operate. In order to get an indication of the operation of the equipment, all points must be checked.
