Daim ntawv pov thawj CE yog xav tau rau kev xa tawm ntawm Voltage test cwj mem mus rau EU
Electric pen, referred to as "electric pen". It is an electrician's tool used to test whether there is electricity in the wire. There is a neon bulb in the pen body. If the neon bulb glows during the test, it means that the wire has electricity or is the live wire of the passage. The nib and tail of the test pen are made of metal material, and the pen holder is made of insulating material. When using the test pen, be sure to touch the metal part of the end of the test pen with your hand, otherwise, because the charged body, the test pen, the human body and the earth do not form a circuit, the neon bubble in the test pen will not emit light, resulting in misjudgment, and it is considered that the charged body Not powered.
Daim ntawv pov thawj CE yog xav tau rau kev xa tawm ntawm tus cwj mem xeem mus rau EU. Daim ntawv pov thawj CE yog daim ntawv pov thawj yuav tsum tau ua los ntawm EU. Tsuas yog tom qab daim ntawv pov thawj CE tuaj yeem muag hauv EU lub teb chaws. Daim ntawv pov thawj CE ntawm lub teeb dej nyab yuav tsum tau ua raws li qhov qis -voltage LVD thiab tib neeg electromagnetic compatibility EMC cov lus qhia!
