Duoyi DY294 - Transistor Tester

[Mr Eastwood]

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 get through!   The withstand voltages for caps feature is a good one.    I think I'll probably not watch the tear-down in case it puts me off using mine again ;-)

I opened mine and looked. Standard for the price, but quite reasonable. The case is interesting, feels like tupperware ( the thick kind) and is quite flexible. As a bonus you can also test MOV's with it, so you can now check your surge suppressors that they still work. Nect for mine is a set of extension leads to test with crocodile clips. 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.

Regarding the brand name - based on the manufacturer's Chinese name, I believe it should be pronounced like “Dwo-Yee” (rhythms with “Wall-E” the Disney movie).
