Highly recommended to create folder for your data with meaningful name
For example uploading user manual for Agilent 34401A multimeter would be great in:

After review data from FTP will be added into site page, if it’s not already there.

Also leaving comment file, like README.txt with link to data source is encouraged, but not neccessary.

All uploads are fully anonymous, unless you add your information in README.txt file or in any similar manner.

How to access it and download documents and manuals from repository?

Sadly due to current situation in the world and russian attack on Ukraine authentication is now mandatory to access the xDevs repository archives. Please contact team[@] mail to request your own unique login and password to repository. It would also be very nice to introduce yourself a bit and confirm your country and town.

If you never contacted before, please introduce yourself and confirm your geographical location (Country and town/city, no need for personal addresses). Just a short paragraph about your interested in test and measurement equipment or technical documentation would be enough. You’ll then get your unique login and password to access the repository.

Information you provide will not be stored anywhere for any purposes, we just want to be friendly community. Making documentation available for older test equipment is also supporting Right for Repair for products that you already bought and own. Making something very complex like the electronics test equipment has huge carbon and ecology footprint, so supporting the Right for Repair by saving your equipment and fixing it with manuals and documentation worth the efforts.

It usually takes few days to get new accounts into the system, please keep that in mind.

Remember, this resource is otherwise freely available, it will never be under any kind of paywall.

And since we all reasonable adults, please not share your login/password with 3rd parties but direct them to this page instead.

Main contact:
