Hi,

Measured a cap without discharging it and now i got a T7 that measures a cell voltage between pins 1 and 2 :)

Removed both the DZ1 DZ2 but the issue remains. Should i assume that the ATmega is toasted ?

Thanks in advance

madires:
Yep, it's toast. You can replace the ATmega or buy a new tester, whatever is simpler or cheaper for you.

Hi all, I'm new to the forum.

I found this thread thanks to the amazing power of search engines, and was glad to make my TC1 work again (it was only detecting a 5V cell whatever what was connected to the leads). The SRV05 was dead, after removal the TC1 worked like before.
What kind of problem will the lack of ZD2 mean to my TC1 tester ? I don't want to fry it for good !!!

Thanks, the amount of good info available here is FANTASTIC !

EDIT: I'd like to upgrade my TC1 firmware. Does anyone in France, preferably near Lyon who does that kind of service ? I'm about to get 2 new TC1 just for spares and would like to have them upgraded as well when I get them. I don't want to do it myself, I don't have the tools nor expertise to do that (and don't want)

Or maybe one of the developers sends the TC1 with latest firmware ?
