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?
This test have similar function like an insulation tester. Home Help Search Login Register. If you use a lower ohm value the non polar cap insulation may breakdown. March 20, HI Siva, How this equipment can used already mentioned in this blog.

As a bonus you can also test MOV’s with it, so you can now check your surge suppressors that they still work. I found that this tester consume lots of current especially testing on the capacitor. December 18, Here is the new eBay listing. Samsung Phone Charger Repair August 19, Jestine Yong September 24, at 9: Leave a Reply Cancel reply Your email address will not be published. If you need to test on non polar cap that have working voltages that is less than v then you may need to add a resistor in parallel so that the insulation of the non polar would not fail when you pump in the volt to the cap.
June 23, I think I’ll probably not watch the tear-down in case mannual puts me off using mine again.

Thanks for the comment. That means if you want to test a 16 volt cap, make sure the charging voltage would not exceed 16 volt.
December 14, If selling in us should include English manual. Please where can one get this to buy and how much is it?

HI Steven, Good question. Testing on Electrolytic Capacitor: Learn how your comment data is processed. If I have the time I will test manuak out. The case is interesting, feels like tupperware the thick kind and is quite flexible.
Looking really useful, I think I will definately order one of these. Another thing is that if the batteries voltage is lower than 5. The disadvantage of this test is you have to wait for the cap to charge up.
Below are the result of certain components that i have tested and i will proceed to provide more information on other components in part 2.
