A very quick and good fix. The customer will keep paying for not taking your advice. Good fix

Good job! I have a cheap plasma cutter which suddenly quit working to. Now I wonder if the problem could be something simple like this?

Of course, Albert. And the worst: when the machine returns for a second service, the customer can wrongly say that the new problem is due to the quality of the first service. Anyhow, a Waleed´s good job. Greetings.

Probably all testers are based on the same old ESR tester firmware. Like the look-alike GM-328 or this one
Always watch out for charged capacitors before testing. They definitely will destroy the probably also AVR processor in your tester if not discharged first! The AVR microcontroller input test pins are very poor protected against higher voltages!
