How to operate the digital galvanometer
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 to be measured is charged, the display lamp on the stylus will light up and the display will show information about the measured voltage scale value.
Generally the stylus can display the information 12v, 36v, 55v, 110v and 220v. Normally the display will end up showing the 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 is close to 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 energized, the display of the stylus shows the information voltage mark.
If the transmission line is disconnected in the middle of the display lamp goes out, the voltage labeling mark subsides, indicating that the location 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.
