keyword=septum current set incorrectlyfor runs 4023-4047, the septum setpoint was set to the current listed on the board/in the runplan. unfortunately, there is typically a 0.5-1.0 A offset between the readback and the setpoint current that increases with current. for future reference, one should only be interested in the readback which is listed as the "Magnet Current", see fig 1. this is the actual readback value and it is accurate to only 0.25-0.50 A. the septum needs to be set such that the readback matches to within 0.25-0.50A of what is listed on the board/in the runplan.
