Operation
All functions of this CryoPlus
storage unit are controlled by
a programmable, state-of-the-
art microprocessor.
Commands to the control
system are given using the
control panel on the cabinet
lid (Figure 2-1). A multi-
colored bar graph on the front
of the cabinet shows the status
of the system, indicating the
liquid level inside the
chamber, and the high level
(stop fill) and low level (start
fill) points. See Figure 2-2.
