Operation method of digital display measuring pen
1. Immediate measurement method
The immediate measurement method refers to the measurement method where the camera of the measuring pen is directly in contact with the measured object to distinguish whether it is charged or not.
When applying the immediate measurement method, touch the metal material camera of the measuring pen with the measured object, and press the immediate precise measurement function key (DIRECT) with your hand;
If the measured object is electrified, the display light on the measuring pen will turn on. Additionally, the display will display information to measure the voltage level.
The general measuring pen can display information of 12V, 36V, 55V, 110V, and 220V. Under normal circumstances, the final displayed information value of the monitor is the measured voltage value.
Immediate measurement method (220V voltage)
2. Magnetic induction measurement method
Magnetic induction measurement method refers to the measurement method of using voltage magnetic induction to distinguish whether the measured object is live or not, by placing the camera of the measuring pen close to but not touching the measured object.
If the transmission line is electrified, the display of the measuring pen displays information and marks indicating the voltage;
If the power transmission line is disconnected in the middle and the display light goes out, the voltage marker disappears, indicating that there is a disconnection in the location.
The magnetic induction measurement method can locate the disconnected part of the insulated wire, and can also distinguish the live and zero wires of the insulated wire.
Electricity provides convenience to our daily lives, but it also carries risks. Therefore, it is recommended to hand over the problems related to electricity to technical professionals to solve, and do not try to be too brave.
