Testing an SCR
When I test an NTE5556 SCR with a multimeter set on diode test, I get 0.6 ohms
with either the positive or negative lead on the annode or cathode. On regular resistence, I get 55 ohms. Shouldn't I only get a low reading in one direction as if testing a diode? The device is not failed, new one checks the same. When I use an in-circuit transistor tester I bought at JayCar, I get open circuit. Doesn't seem to respond like a normal SCR. |
