Entering Run Parameters
When the power is applied for the initial use (no previous runs), default values are displayed
(see
Figure 2.2 ). After the initial use, the parameters of the latest previous run are displayed when
power is applied.
When run parameters for a rotor have been entered, as described below, they are retained in the
centrifuge memory. The recalled program can then be used for the current run or altered as
required. See
Saving Settings .
