Yes, by reprogramming U4 and switching to k or m-firmware.

OK thank you.

To do this, I would first have to deal intensively with this topic.  :-\
Let's see how much time I can and must invest.  ^-^

Hi!

I also have a Longruner brand TC1 that has the same problem, this only measures a cell voltage, this 5.04v case Whatever I put in the the thing. Nor can I have it enter calibration mode.

Looking at this same post about the answers, I managed to verify the DZ1 and DZ2 and these work correctly, so I had come to the conclusion that I need to change the atmega324pa. I am from Argentina and it is difficult to get this microcontroller in the market, can there be someone else I can replace? also another query, if I do get to buy 324 fro
