1.need check chip,adapter connection, Clean the socket,adapter,chip.
2.select "insertion test" and "device ID check" on software. if both ok, you can modify VCC between 2.7V-3.6V. menu "setting"->"modify algo...".

Thank you.
VCC 3,3V is working for reading. Now i getting equal outputs.
If i change VCC (in setting->modify algo), pres OK and again open "modify algo windows", there is 3,00V. Is it OK?

But writing still fails.

if change 3.3V then press ok. open again, it should be 3.3V,no change.
but if chip re-select,it will return initial value.
for writing fails, please selece "slow program/read" in the middle of the view.

There was a problem in decimal point. In my windows setting i have decimal point "," not "."
In wellon software i see 3,00 but i have to input 3.3 for change.
If i input 3.3 noting is changed.

Writing to eeprom is working at 3,35V

Thank you for your help.
