【More Safe】CE CAT.II300V RoHS Certificate. No gloves are recommended during the test, Testing AC voltage needs the human body and ground wire to form a circuit. No Electric Shock Risk, No Dangerous, More Accurate Readings. The current flowing through the human body is less than 0.1uA. (Min current the human body sense：1mA). The internal circuit of the Voltage Pen is connected in series with a large resistor, which will burn out when the current is too large, and the circuit will disconnect.
