How to operate a digital display pen
1. Direct measuring technique
The term "immediate measurement method" refers to a measuring technique where the test pen's camera directly contacts the object being measured to determine whether it is charged or not.
Hold down the immediate and precise measurement function key (DIRECT) while using the immediate measurement method by touching the metal material camera of the test pen to the thing to be measured;
The test pen's display light will illuminate and inform you of the detected voltage value if the object being tested is charged.
12v, 36v, 55v, 110v, and 220v information can be seen on a general test pen. Under typical conditions, the detected voltage value is marked on the display's final display information.

2. A technique for measuring magnetic induction
The term "magnetic induction measurement method" refers to a measuring technique that places the test pen's camera close to the object being measured but not directly on it. Voltage magnetic induction is used to determine whether the object being measured is charged or not.
The test pen display will show the information voltage indication if the power transmission line is live;
If the transmission line's middle disconnection indicator is off and the voltage indicator starts to fade, a disconnection has occurred there.
The insulated wire's disconnected portion can be located using the magnetic induction measuring technique, which also allows for the separation of the live and neutral wires.
