Preselection

3.4.1

Preselection of speed / RCF-value

This pre-selection is activated through the key "RPM | RCF" (4) (refer to figure 19 below). By pressing the key
once the word "rpm" (M5) flashes. By pressing the key twice the pre-selection of the centrifugal forces can be
selected. Then the flashing word "rcf" (M6) appears. You can set the desired values with the adjusting knob (1). In
the display (A-1) the regulated value is shown permanently, before, during and after the run.

The speed is adjustable between 200 rpm and maximum revolution of the centrifuge resp. the maximum
permissible revolution of the pre-selected rotor.
It is the same as the pre-selection of the RCF-value. The setting range is between 20 x g and the maximum
permissible centrifugal force of the rotor.
The maximum speed of the FC5706 is 6000 rpm resp. 4427 x g.
See "Table 3: max. speed and RCF-values for permissible rotor" (See APPENDIX). All important values are
listed there.
ATTENTION:
Please also check the maximum permissible revolutions of your test tubes with the manufacturer.
3.4.2

Preselection of running time

The running time can be pre-selected in three different ranges from 10 seconds up to 99 hours 59 minutes.
1. Range from 10 seconds up to 59 minutes 50 seconds in steps of 10 seconds
2. Range from 1 hour up to 99 hours 59 minutes in steps of 1 minute
3. The continuous run "cont", can be interrupted by the key "Stop"(10).
The running time can be pre-selected with the lid open or closed.
To activate the setting of the running time press the key "Time" (6).
In the display "Time" (A-3) the indication "m : s" or "h : m" flashes, depending on the previous setting.
Set the desired value by using the adjusting knob (1). After exceeding 59 min 50 sec the indication changes
automatically into "h : m". After exceeding 99 hours 59 min the word "cont" appears in the display "Time" (A-3).
That continuous run can only be interrupted by pressing the key "Stop" (10). The time starts counting down as
soon as the set speed is reached.
The display always shows the remaining running time. (See figure 20)
All with number marked passages refer to figure 20
