The operation method of digital 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 object being measured to distinguish whether it is charged or not.
When applying the immediate measurement method, touch the metal material camera of the measuring pen to the object being measured, and hold the direct precise measurement function key (DICT) with your hand;
If the object being measured is charged, the display light on the measuring pen will turn on, and the display information will indicate the standard value of the measured voltage.
A general test pen can display information of 12V, 36V, 55V, 110V, and 220V. Under normal circumstances, the final displayed information value on 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 object being measured is electrified by placing the camera of the measuring pen close to it but not touching it.
If the transmission line is live, the voltage indicator displayed on the display of the measuring pen should indicate the voltage;
If the display light in the middle of the power transmission line is off and the voltage marker disappears, it indicates that there is a disconnection in the location.
The magnetic induction measurement method can locate the disconnected part of insulated wires and can also distinguish between live and neutral wires of insulated wires.
Electricity has brought convenience to our daily lives, but it also carries risks. Therefore, it is recommended to hand over the difficulties related to electricity to technical professionals for resolution, and not to be presumptuous.
