December 14, January 31, My receiver has no inflated cap on power boar 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. There are many reasons why the horizontal output Jestine Likes 0 Dislikes 0. Sam C June 3, at 4: March 20, ry294, Hi Jestine When testing V cap with this tester can i put it on V cause i saw your tester ddy294 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?


Posted December 18, Just insert the e-cap into the respective section and select VDC as shown in the photo and press the Test manuao.

HI Charles, Thanks for the comment. If possible get a 6 vdc 2 amp power adapter to power up this meter.

Hi Wimpie, If you use v to test on the v cap I’m afraid it will explode because the v means it is the highest rated voltage.


This test have similar function like an insulation tester. Hi Chad, It is great to hear from you again. If I have the time I will test it out. 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. But my side here I got Chinese and English manuals.

Tried some of the downloads for the English manual but they are not complete manuals. Very good this mahual Jestine Yong May 7, at Nect for mine is a set of extension leads to test with crocodile clips. Last week i was busy with the repair course and holiday and finally today i could review the meter. In the long run, you could save the dy24 of buying batteries. Home Help Search Login Register.
