Self-test function
During the self-test before use, hold the pen tip with one hand and lightly touch the end of the pen with the other hand. The light indicates that the test pen is normal and the power is sufficient. No light indicates that the battery needs to be replaced.
Automatic recognition
As long as it is near the insulation layer of the cable, the plastic cover of the electrical appliance, etc. when the light is switched on, this means that the line is live. The brighter the light, the higher the voltage of the circuit under test.
Find stop
Hold the bottom of the pin with one hand and the tip of the pin touches the wire. It can be used to find breakpoints in everyday household appliances such as rice cookers, computers and power strips.
