ESR Meter Extension to Test Component Under Load

I made this add on for ESR Meter since I found something strange from my experiment. There is another way to test flyback or transformer which are still energized with bulb, but this add on still serve me well, so far so good. 



By the way, you could test yoke too with this add on for your ESR Meter and don't forget about the note. Have a good day and still be careful when doing repair job. Thank you for coming here.

See this great idea that I created and kindly post by Mr Jestine Yong on his blog. You can test flyback and SMPS transformer under load with this.
