WebMar 22, 2024 · How do you test a thyristor rectifier? Connect the negative lead of your ohmmeter to the anode of the SCR and the positive lead to the cathode of the SCR. Read the resistance value that is displayed on the ohmmeter. It should read a very high value of resistance. If it reads a very low value, then the SCR is shorted and should be replaced. WebTested with a multimeter in the “resistance” or “diode check” modes, a transistor behaves like two back-to-back PN (diode) junctions. The emitter-base PN junction has a slightly greater forward voltage drop than the collector-base PN junction, because of heavier doping of the emitter semiconductor layer.
