Hi Jestine When testing V cap with this tester can i put it on V cause i saw your tester were on V just want to make sure and i have a 6V mA external power supply measuring over 7V with digital tester will this power supply be ok? I have not tested these components yet.

Looking really useful, I think I will definately order one of these. HI Steven, Good question. Stay tune for more testing result in Part 2. That means if you want to test a 16 volt cap, make sure the charging voltage would not exceed 16 volt.

That is a lollipop also. Hi John, Yes i recommend it too. Posted December 28, Hi Willie, Here is the part 2 and 3: Set to v to test on non polar cap that have working voltage of 1kv and above. Jestine Yong September 24, at 9: Another thing is that if the batteries voltage is lower than 5. I think I’ll probably not watch the tear-down in case it puts me off using mine again ;- Logged Hey!

Hi Beh, It does test the Varistor. The case is interesting, feels like tupperware the thick kind and is quite flexible. Hi my dear jestine. Must get a scrap board with a molex plug on it and cut it out and remove unneeded pins to make the plug in portion, then 3 leads with croc clips I have some here from Frankie as well to use on short leads.
