Sensitivity control

This switch controls the full range of the current in the magnet. If the setting is at 100%, the range is larger but coarser (212 possible settings regardless of the range), and on the 20% setting the range is smaller but finer which may be required in some cases.

In the summer 1999 run, all the magnets were operating in 100% mode. If that is changed to "20%", the new DAC value(s) should be set.
