* Check the currents in the Spectrograph dipoles by looking at the EPICS channels I265DS and I269DS. This can be done e.g. by clicking the button **Details** in segment 8 of the S800 Barney page (see figure below) | * Check the currents in the Spectrograph dipoles by looking at the EPICS channels I265DS and I269DS.
