How to use a multimeter to test the way SCR Thyristors SCR also known in the electric and electronic fields have a very wide range of applications. Where the weak areas in the application of SCR power is relatively small, it looks like a transistor, is one element of electronic enthusiasts often encountered. SCR is the correct test electronics enthusiasts must have the basic skills. How to test SCR it? Because fans must be equipped with an electronic multimeter tool Here's how to use a multimeter to test the way SCR. Way thyristor test includes two aspects: First, determine the polarity; the second is triggered feature tests. SCR polarity determination multimeter R × 1K range measuring positive and negative resistance SCR poles, positive and negative resistance to elect two very big difference SCR T405-600T, in which the measured resistance smaller that measurement, the black pen connects to a control electrode (G) SCR 2P4M, red table pen connects to the cathode (K), the rest of a pole on the anode (A). By determining the polarity of thyristor also be qualitatively determined that the SCR is good or bad. If the positive and negative resistance between the poles are any small difference in the test, the resistance are large SCR, indicating G, open-circuit fault exists between K; if there are positive and negative resistance between the poles is very small, and is close to zero, the SCR internal short circuit fault exists between the poles. SCR SCR _ C106M_ are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd .. Dongguan City is Wal-Electronic Technology Co., Ltd.
