It test just the same way for a non polar cap. Jestine, Did you ever do part 2? Home Help Search Login Register. If I have the time I will test it out.

Duoyi DY – Transistor Tester

March 20, Looking really useful, I think I will definately order one of these. I found that this tester consume lots of current especially testing on the capacitor. Purchased one of the dy tester the manual is in Chinese so that does not do you a lot of good. The external voltage is 7 volt when there is no load but with load it will go down thus you can use it on your meter.

In the photo below, i found that the resistor of kOhm is suitable to test on a non polar cap that have volt working voltage.

Last week i was busy d294 the repair course and holiday and finally today i could review the meter. Arnold Codilla August 10, at The LCD display will show the capacitor is charging and it will charge up to vdc-make sure that you are testing a cap that have working voltage higher than volt.


If possible get a 6 vdc 2 amp power adapter to power up this meter. Hi my dear jestine. But my side here I got Chinese and English manuals. I have not tested these components yet. Thanks for the comment. March 21, HI Charles, Thanks for the comment. Please where can one get this to buy and how much is it? Jestine Yong September 24, at 9: Learn how your comment data is processed. The withstand voltages for caps feature is a good one. Just make sure that when you want to test a lower voltage of capacitor, the charging voltage should not exceed the working voltage.
