The think I love the most about this capacitor tester is that you don’t have to hold push buttons in to do a leakage test on electrolytic capacitors.
Most testers you dial up the test ieco, push the leakage button and wait for the eye tube to open which seems like forever. This unit you simply increase the voltage a little at a a time while watching elco eye tube to show the capacitor under test is taking the charge. I have to disclose, I learned this from U-tube videos. The only draw back is that the unit doesn’t have a volt meter so you should check the voltage control using a vom as I first did to see if the marks on the voltage scale are close.

I am a Electronic Tech. It seems to be one of the most popular units out there. I replaced 3 capacitors 2 didn’t.
I added a line fuse and replaced the line cord with a polarized manuaal. The unit worked when I got it and the changes I made were for safety reasons.
