Hello everyone
I am trying to fix a 2015 Kiethley that is stuck.
Its display reads "No comm link"
Before any intervention I decide to save the firmware and files of setting
I have already read several post very interesting on this site
I bought a TLC866 II
It allowed me to back up ODD and EVEN firmware
By cons I do not know how to save the data "instrument setup and calibration constant" which is on the eeprom 24lc16b (U136)
on this page it is about the parametric data backup of a k-2001 by realizing a "DIY I2C dongle" to connect to the TLC866:

Is the procedure the same on a 2001 and 2015?
Should it desolder 24lc16B?
in advance thank you for your help
