Default Re: LCR T7 tester problem

Your fuse map should be this according to the file attached by stj if you are trying to load the "original" firmware:
Extended: 0xFF (Or 0x07 it depends on the program version how it reads the map, everything should be disabled)
High: 0xD9
Low: 0xE2

If you look in your picture the "high" fuse map is already 0xD9 and extended map is 0x07
So you only need to change the "low" map by deselecting "CKDIV8"
Verify that this changes the low fuse map value at the top from 0x62 to 0xE2
If it does you can program the fuse map.
