Selecting the run time
You can select a run time between 1 and 99 min or
continuous operation.
For hematocrit determinations you
should select a run time of 10 min for a
standard blood column of about
65 mm.
The evaluation of hematocrit measurements is detailed
on page 35.
Preselected run time
To predetermine the run time, proceed as follows:
1. Press the "set" key in the "time" panel (press twice if
the centrifuge is in the standby mode). The run time
last entered appears in the display. The right-hand
digit (in the example on the following page the figure
"5") flashes, thus indicating that you can change the
setting in minutes.
2. Press one of the "set" keys "+" (increase) or "-" (de-
crease). By pressing the selected key briefly , you
increase or decrease the preset run time in steps of
1 min. This option is supposed to be used for small
changes and fine tuning.
3. If you keep the key pressed, the display changes at
first slowly and after a few seconds at an acceler-
ated pace.
4. Release the key as soon as you are close to the
desired value and fine tune if necessary by repeat-
edly pressing the selected key (or its counterpart if
you have proceeded too far). The display keeps
flashing. The run time is stored by again pressing
one of the "set" keys or "start".
Continuous operation
For continuous operation, press the "set" key in the
"time" panel and then the "-" key until "hd" (for "hold")
appears in the display.
With this setting, the centrifuge keeps running until
stopped manually.
Please note that the lifetime of centrifuge tubes, par-
ticularly plastic ones, is limited, and that they may be
damaged by continuous operation!
