*Internal circuit diagram
When the tip contacts the electric DC line, the current flows according to the below chart.

This current is amplified in the circuit, lighting the lamp and making the buzzer sound, thus the detector indicates whether the subject line is charging or not.

* In the case of AC, the current flows according to the below chart.
