Review of the DY Digital Transistor Tester – Download as Word Doc .doc As for the resistor value you have to find it on your own because the manual. Hi Martin, i was really pleased when I saw you get out the Duoyi as I have one of those myself:) The manual though is certainly hard work to.

Last week i was busy with the repair course and holiday and finally today i could review the meter. Select to the range as shown in the photo below and you will know the total voltage of the internal batteries:. 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.
There is only one range for you to select to test the non polar cap- v. The volt produce no result when test on non polar cap. Set to v to test on non polar cap that have working voltage of 1kv and above. For a good cap, it will show approximately v and if the non polar cap insulation have problem, it will show a very low voltage from 60 to about volt.
This test have similar function like an insulation tester. If you need to test on non maanual cap that have working voltages that is dt294 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.
As for the resistor value you have to find it on your own because the manual does not comes with it. 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.
If you use a lower ohm value the non polar cap insulation may breakdown. From the same photo you could see that the max voltage only hit volt. If this non polar cap insulation have problem, the value could be less than volt. For your information, this meter is not design to test on the ESR or the capacitance value of e-caps.
It test just the same way for a non polar cap. Just insert the e-cap into the respective section and select VDC as shown in the photo and press the Test button. 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.
The disadvantage of this test is you have to wait for the cap to charge up. The advantage of this meter over insulation tester is that it can be used to test on e-caps that have lower working voltage like 16 volt, 25 volt, 50 volts and etc.
Just make sure that when you want to test a lower voltage of capacitor, the charging voltage should not exceed the working voltage. That means if you want to test a 16 volt cap, make sure the charging voltage would not exceed 16 volt.
If there is a problem with the cap, there would be no charging or the charging would just stay at one value for example it stays at 8 volt and stop. I found that this tester consume lots of current especially testing on the capacitor. If possible get a 6 vdc 2 amp power adapter to power up this meter.
In the long run, you could save the cost of buying batteries. Another xy294 is that if the batteries voltage is lower than 5. Stay tune for more testing result in Part 2. Looking really useful, I think I will definately order one of these.
I like that it can be used as an insulation tester and for testing varistors. Used to be free shipping. Here is the new eBay listing.
Purchased one of the dy tester the manual is in Chinese so that does not do you a lot of good. Manuap some of the downloads for the English manual but they are not complete manuals.
Just thought i would let the people know before ordering one. If selling in us should include English manual. Thanks for the comment.

But my side here I got Chinese and English manuals. The English manual is a bit blur mznual still can be read. How this equipment can used already mentioned in this blog. For other equipment i suggest that you get this maual at http: Hi Jestine When testing V cap with this tester can i put d294 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?
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. 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.
HI Steven, Good question. I have not tested these components yet. If I have the time I will test it out.
