The test circuit for an SCR is both practical as a diagnostic tool for checking suspected SCRs and also an excellent aid to understanding basic SCR operation. A DC voltage source is used for powering the circuit, and two pushbutton switches are used to latch and unlatch the SCR, respectively: (Figure below)
A multimeter can be used to test SCRs quite effectively. The first procedure is to check the diode action between the gate and cathode terminals of the SCR. This test is just like what you have done in the case of testing a silicon diode (see testing a silicon diode).

17 sty 2018 · An SCR tester circuit diagram is made up of various components. These include a voltage source, resistors, diodes, capacitors, and transistors. Each component is represented by a different symbol on the diagram, making it easy to identify what each one does.
13 lip 2021 · The Simple SCR tester circuit diagram is very useful. We can know the location pin on the gate lead, anode lead and cathode lead. And can also test diode, LED and Triac.
10 sty 2018 · In this post we learn how to test a SCR whether it's good or bad using a couple of simple circuit implementations. Simple SCR testing circuit. Referring to the diagram below initializing the shown normally-open “on” push to ON button connects the gate to the anode, enabling current coming from the negative lead of the battery, by means of ...
4 sty 2021 · SCR Tester Circuit. This useful little SCR circuit can provide you with a visible indication, is a one afternoon project, and it is simple to put together. Figure 1 exhibits a 3 -amp, 50 -volt SCR and a experiment circuit. A fixed resistor works extremely well for R1.
