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) SCR testing circuit
Testing SCR using a multimeter. 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.
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.
20 cze 2023 · In this tutorial, we are going to demonstrate a TRIAC or SCR Tester circuit. TRIAC or SCR is a useful component even though it is not used in all electronic devices or circuits but they perform very essential tasks in some circuits. TRIAC/SCR can be tested using a multimeter.
