Run time selection
To predetermine the fixed run time, proceed as follows:

(for decrease) in the field "time" of the control panel
to enter the pre-selected value mode (cf. foldout
leaf in the cover):
By pressing the selected key
briefly, you increase or de-
crease the preset run time in
steps of 1 min. This option is
supposed to be used for small
changes and fine tuning.
2. If you keep the key pressed, the display changes at
first slowly and after a few seconds at an acceler-
ated pace to the higher or lower values.
30
(for increase) or
3. Release the key as soon as you have reached the
desired value and fine tune if necessary by repeat-
edly briefly pressing one of the keys. The run time
display flashes for a number of seconds, then
changes to permanent display of the current value
mode. The new pre-selected run time is now stored.
Continuous operation
To operate the centrifuge in the continuous mode, you
must press the key
until the display changes to „hd"
(for "hold").
In this mode the centrifuge runs
until you stop the run by manually
pressing the „Stop"-button

plastic rotor tubes is limited. Continuous
operation (extended use) may cause dam-
age to them!
