Sometimes you need to test the functionality of a high-power triac.
This video shows a simple test method.
This video is aimed at the beginning radio amateur.
The video mentions "#LCR-T3 Transistor Tester"—a very convenient and useful tool for a radio amateur. It can determine the pinout of radio components, their type, and their ratings. I've been using it for over a year and am very happy with it.
