Field Effect Transistor Tester

This picture of Field Effect Transistor Tester came from Mr. Beh. I shared to him the circuit link and he makes one. Before he made one of this tester. He has a circuit that he plan to build it. But prior to that i told him that circuit of fet tester is not working because i made that one before. And I told him this picture which i link him the circuit that works to test a FET. Thanks to Mr. Beh for the picture. Congratulations. You have another helper to troubleshoot electronics.
