The use of liquid crystal digital display inductance stylus
First of all, said the induction pen to measure the fire line zero line, directly in the outer skin test will be bright is fire, short-circuit is the same, along the wire measurement, to be close to a little bit next to the wire, but the induction pen very few people use now, because of the impact of environmental factors is too much to measure the results are not very accurate!
① This power pen not only can measure AC 220 Ⅴ, can also measure 110V, even as low as 12V, can also measure DC. Specific methods of use refer to the manual, not described here.
② induction distance is not very far, I usually stick to the wire insulation skin test. Fire and zero wire twisted together must be separated, otherwise the measurement is not allowed. I think it can be measured against the skin on the line, the distance is not allowed that is not also necessary.
③ If you can separate each wire, and know which wire is broken, not the kind of wire handle type, electric pen against the outer skin of the wire to find the break point is still very convenient.
④ If it is a handful of wires, the wires must be dispersed in order to measure the charged wires without stripping the outer skin.
The use of inductive stylus, and digital multimeter, as in practice, need to continue to explore, and constantly sum up the experience, in order to master the effective testing methods, for my use.
