Hola, yo tengo un probador de esotos el MC JL294-3, y no tengo mucha informacion de su uso y de los signos que tiene en Chino me imagino. Tendra algun manual de usuario o instructivo de uso?.

Espero pueda ayudarme, gracias.

Hi,

I suggest that you get a normal digital multimeter that have the hfe function to test on the transistor which is much easier unless you want to buy the DY294. I do not have jl294-3 meter thus i can't give any comment on this.

Dear Mr. Yong,
Please give me a commit for DY294 vs JL 294-3.
I need to do the test occasionly, most on HFE.
Which one is convient to use? better functions? I can only afford one for my hobby.
I also have a curve tracer with separate OSC for serious measurement.
This one will be used for safe/fail and preliminary test.
But accuracy is still wished.
Please send me a mail soon. By the way, accuracy comes first than the multiple functions. If they are the same, I will choose DY294 with a external power plug, I do not trust the battery very much, specially test on larger size transister.

its very nice device but need to be thinked , accuracy will be maintained by analogue meter testing .
i like to test component with analogue AVO meter because off accuracy test and reliability.
otherwise, its upto the repairer what will be the best precision test equipment for them.

thanks you
regards
