Go to the window area 'Fuses & lock bits', change the values in the text boxes and click 'Write'. BTW, the main problem is that the ATmega runs with the wrong clock settings.

No, the firmware is already programmed.

Please read the fuse bits to verify that they are really changed.

Then remove the programming cable and power cycle the tester.

really weird,...

47uF cap no problem, 100uf stay's okay  but with 1000uF or higher the cap triples in value and no esr
with the calibration at the end you have to insert a +100nF cap as with the old firmware 1.11 but with this firmware i get this screen, i can't remember if it was like that before

I don't know what...
You should say that you have to insert a cap from 10nF or 22nF
With the 1.11 firmware that was never an option...
But it makes no sense as it comes that those large caps triple in value...

Well when changing the chip forgot to somw heat resistant tape over C10 & C12 they were 45 degrees shifted so i placed then sideways on the board lol
I Burned the chip another time and now the 2000uF cap is quite okay, the esr is working also.
When burning the chip i got an error:
device 0x04 != input 0x00 at addr 0x0079 (error)
avrdude error: verification mismatch
And on the tester i saw a few weird icons... going to check it tomorrow... i've done with damn tester lol but learned a-lot
Going to catch sum sleep  :=\
Thnx Madires!
