Hi Owais,
It's been a long time. Good to hear from you again.

Thanks.

Nice article. I use this method and most of the time I use my zener diode tester which design I got from Mr. Jestine Yong. The tester is more fast and accurate and save time and risk of overheating of Zener diode. But I can say that both methods of testing Zener diode is accurate and powerful because we supplied full operating voltage and safe current in order to test Zener diode accurate.

Hi Guy's,
I was thinking about using my Variable Isolation Transformer as a power source, feeding through a Bridge Rectifier, and using a circuit like yalls for testing high voltage Zeners. I forgot about it until just now. I got to doing other stuff and forgot about it.

Also, the DCA75 Pro uses a AAA 1.5V Alkaline battery. I hope your friend didn't put a 12V battery in it.

Hi Albert,

Maybe your friend had a bad battery. I have never had any problems with my Peak Atlas Analyzers, and I have 4 of them.
The DCA75 Pro will only check Thyristors that have gate currents up to about 10mA. For thyristors with larger gate currents you need to get the SCR100 Triac & Thyristor Analyzer. They are great tools and you may be able to order them from their website in England.

I will check if I have one LM317. If I found one then I will see how can I make the checking method and I will post it.
Thanks for supporting my article.

Dear Christian Robert Adzic sir
Can you please put an article on " Another method of checking LM317 IC ".

Robert,
A very good and straight forward tutorial.
You explained in simple terms.
Sometimes we have difficulties in identifying the zener diodes. Yes this is the way I like it.
Thank you. Hope more articles will come.
