[Soungai00]

Here is the implementation i made for using keithley multimeters from the 2700 series (tested with 2700/2701).

thanks for the PR,
please look at the comments
also you should consider using the already existing driver from pymeasure:

do you want me to review it? Then you should reply to each of my review points for me to know if you took it into consideration

[Soungai00]

Oh sorry I indeed worked on your review points but since I was mainly checking them from the "Files chanded" section I just saw most of them disappeared when I pushed the commits and forgot to reply to each in the "Conversation" section. I still want to change the FRONT/REAR parameters to make them show/hide but I will reply to each preview point I worked on.

I don't understand the presence of the SQL requirements. Other that this, it is fine. Make sure to have a look at the pymeasure implementation!

Thanks ! I checked the pymeasure package recently and I am thinking of how I can use it to implement a 2nd version of the keithley_plugin with pymeasure. I'm not sure all the features I use are on pymeasure but I will try to fork pymeasure and add them if needed.

Thanks for the work!
I released a new version including your instrument!
