TEST PEN

Usage :
1. When the pen senses or detects voltage, the white part of the pen lights up and buzzes. It is easy to detect firewire and know which line has dangerous voltage. 2. There is a button in the middle of the induction pen. Press it and a highlighted LED will shine at the tip of the pen.

Instrument maintenance: 
1. This instrument is safe and insulated. To ensure safety, please keep it dry and clean during storage and use. 2. If the LED lamp does not work, please replace the battery. If it is not used for a long time, the battery needs to be removed to prevent leakage from damaging the instrument.
