Re: ESR meter upgrades

I hope you can help me. I am searching for a new Tester. After moving to a new location i can not find my old gm-328 (modded with new quarz. . . .).
I am not planing to mod the new one. But i was checking what is available out there and found a version with PWM Generator (would be helpfull when working with leds /modding led circuits). https://www.banggood.com/de/9-12V-DC...rrency=EUR&amp...

Re: ESR meter upgrades

A few days ago my Tester DIY Kit arrived. But without any documentation. Only the PCB and the parts.
My question is if someone with the same tester can take a picture of it without the LCD installed? That would help a lot.

And i want to ask if it is possible to protect the tester against a charged capacitor. Or better protect the tester in case i forget to discharged a capacitor.
That are the parts i got from ebay (the 16Mhz crystal is still in transit but the LM4040 is already here)

Yes it is this one http://www.ebay.de/itm/GM328-Transis...cAAOSw0fhXki5S

Re: ESR meter upgrades

Thanks that would be nice!
And can you also help with the other chip. I think it was a 5V low dropout voltage regulator. But i can not find the chip at Conrad Elektronics. But maybe they have something similar that i can use.

Re: ESR meter upgrades

The Programmer has arrived. Now i am waiting for the Kit to arrive.
One question. Can someone check if i have found the right PMIC (https://www.conrad.de/de/pmic-spannu...html?insert=62).
A friend works nearbuy this shop and can get it for me. So i do not have to pay for shipping.
There was a second chip to increase the battery runtime but i can not find it in this shop. And i do not have the knowledge to check for a chip with similar characteristics.
Maybe someone...

Re: ESR meter upgrades

Dam the ebay seller is not shipping to Germany. This should be the same if i am right.

And because RS is really pricy in Germany (more than 8€ for shipping) i want to ask if i can use this crystall. It is not a 10ppm.

And because i can not find my old programmer (i used it to programm Atiny 13A chips for my flashlights). ...

Re: ESR meter upgrades



Which one would you recommend? Or is changing the crystall a solution?...
