LOCK

UNLOCK

CENTRE

The 3 commands LOCK,
UNLOCK, and CENTRE are
simply entered at the command line.
While they are executing the system
displays the mass positions for the 3
components updated once per second
(3 seconds to cycle through the 3
components). The mass positions are
measured to 16 bits so when the
masses are locked the displayed
readings will be in the region of 32k
or -32k. When the masses are
correctly centred the readings should
be less than 1000 counts.
