Multimetre kısa devre
First, insert the black test lead of the multimeter into the 22com" hole, insert the red test lead into the "V Ω" hole, and turn the topuz to the buzzer position. Bağlantıyı Kes the power supply of the test circuit, and test the two wires of the circuit with two test leads. If the resistance of the multimeter shows {{{{{}}}}}} and there is a biep, it means that there is a short circuit in the circuit. You can also use the ohm 1k or 10k range, disconnect the other end of the line, and test the two line with two test leads. If the resistance of the multimeter shows 0, it means that there is a short circuit in the line.

When we are testing the continuity of the line, we must disconnect the power before testing. Turn the button switch to buzzer position, and test that the two ends of the line are in contact with the metal needles of the test pen. If there is a certain resistance and there is a buzzing sound, it means that the line is connected; if the resistance is infinite, it will be display as 1. And there is no biep, the line disconnected. Or select the the 1{{{}}k range of the multimeter, short-circuit the other end of the line, and test the two lines with the test leads of the multimeter. If the resistance of the multimeter shows 1, it means an open circuit; if it shows 0, the line may be connected.

1. The red and black pen of the multimeter is on the stake, which can be pulled out at will. I saw a metal male soket connected to a leather wire. Çünkü the wire point of this wire post is easy to break, I tell you that the wire of my test pen is much shorter. , I have repaired it many times, and I waste 1 santimetre each time. I have tamir edildi her iki tür saat (elektronik ve işaretçiler). , kelepçe metal kazık on the vise, eriyik lehim tel ile a lehimleme demir, ve sonra şerit kapalı deri tel yarım a santimetre teşhir teşhir bakır tel, ve eriyik it teneke ile. O o en iyi koy an yalıtım balmumu tüp on the wire, so that after welding, the outside It is not easy to break with with kasa.
2. The wire post of the digital meter is not easy to weld, its plastic sleeve is big and hard, you have to pull it out first and put the wire in, and then return it to its original position after welding on the outside, if you do not even have welding skills No, it would be difficult!
