Curt, Tux, thanks, but that is not what we're talking about here.
Thanks 40hz, that are well suited headings for my documentations."Basic Preparation""Software Setup and Configuration"
Initial Software Setup
Check Software Installation
Settings & Data Backup"Hardware Setup and Configuration"
Check Instrument Connection
Detailed Live Test
"Hardware Setup and Configuration" is what we would call "Inbetriebnahme" and for what I had searched for an short, handy term like "Commissioning"
Thank you all for your support, very appreciated
