2 ways to operate a digital stylus
1. Immediate measurement method
Immediate measurement method means that the camera of the stylus will touch the measured object directly to distinguish whether it is an electrically charged measurement method.
In the application of the immediate measurement method, the metal material of the stylus camera touches the object to be measured, the other hand presses the immediate and accurate measurement function key (DIRECT) did not let go.
If the object is electrically charged, the display lamp on the stylus lights up and the display shows information on the measured voltage scale.
Generally, the stylus can display 12v, 36v, 55v, 110v and 220v. In general, the display will show the final value of the measured voltage.
Immediate measurement method (220v voltage)
2, magnetic induction measurement method
Magnetic induction measurement method means that the camera of the stylus close but not touch the measured object, the use of voltage magnetic induction to distinguish the measured object is not charged measurement method.
If the transmission line is charged, the display of the stylus will show the information voltage mark; if the transmission line is disconnected in the middle of the line, the stylus will show the information voltage mark.
If the transmission line is disconnected in the middle of the display lamp goes out, the voltage marking mark fades, indicating that the location of the existence of the disconnection.
Magnetic induction measurement method can find the disconnected part of the insulated wire, but also can be carried out on the insulated wire to distinguish between the fire wire and zero wire.
Electricity gives us a convenient daily life, but there are also risks, so the electricity-related problems are still proposed to the technical professional staff to solve, do not try to be brave.
