[Dsg-hallb_magnets] Questions hexbeam SG signals

[Pablo Campero]

Hello Nick, 



I've been looking at the logbook entries this morning and I have a couple of questions (log number 3436321 ) and maybe you can help me. 



1. Is this EM Differential value between the EM Baseline and the Force value in the Hexbeam Strain gauges EPICs screen ? 



2. Is the EM Baseline value display in Hexbeam Strain gauges EPICs screen measured before cool down the magnet? Or when is this value measured? 



3. I've trying to get the same signals in the Myaviewer Archive but I had some issues to get the same for SG817U1HB4:EM_DIFF signal (see attached picture). I got negative values. How do I get that signal? 



Thank you in advance. 





With Regards 

Pablo
