Awesome tester, thanks for sharing!

[@marcbaflast7271]

Belle réalisation utile et indispensable entouré circonstances de dépannage.

muito bom parabens falta a linha de transistor 2n um soquete de 5 furos testa todas as posiçoes do transistor seria assim e b c e b as posiçoes sao bce ceb ebc bec cbe ecb to montando o meu isto e ja montei 23 testes e vendi todos mas agora encareceu tudo e por isso nao vendo mais mas ficou show to pretendendo montar um teste de integrado cd4001,4011,4093 741 555 e muito mais integrado conhecidos

Do the Mosfet Tester test the 2 types N and P?

[@gnasser76]

is there a way to add igbt tester ?

[@revyuvan6647]

Does it test both p type and n type MOSFET

[@shivavelishoju5830]

Can I use 10mf 63volt capacitor

[@edsonquispe2212]

the transistor tester is npn or pnp?

[@birennagi2613]

Only red led blinking for transistor tester. Please give solution.

[@Randdannoura9115]

Ok

[@jojovallido9127]

Pwede ba N channel at P channel yn

[@balasubramanid5411]

Can we check both PNP And NPN transistors using the same circuit.please reply

[@sujeevanishanthakumara6171]

@@MAHEEJGallery befor u press the push button your led is slightly blinking ,is that must.

Hi my teacher I make transistor tester would you please tel me why the only red led is on and green led is off

[@hasanashrafi6467]

Thank you

[@hasanashrafi6467]

But I have only red led on and never green led on without blank led
