Selecting speed
The centrifuge speed can be set to a minimum of 300
rpm and to a maximum of 15 000 rpm (depending on
the rotor).
You can adjust the speed in 10 rpm increments. Pro-
ceed as follows:
1. By pressing the adjusting knob in the „speed“ field
of the control panel once you switch from the pre-
sent to the set value mode. The value stored last is
shown in the display with the set value input flash-
ing. (If there is no value in the store the display
shows ----- dashes.)
2. By adjusting clockwise the set value is increased,
by adjusting counter-clockwise the set value is de-
creased. The incremental range depends on the
speed (minimum 10 min
-1
per snapping).
3. After the required value has been achieved the
decimal place is flashing several seconds and the
display changes to the present value. The speed
has been stored now.
By pressing the adjusting knob once again
the set value mode may be left before the
end of the waiting period, enhancing the
input
Entering the RCF value
You can adjust the RCF set point in steps of 1. The set
point is entered analogously to the speed.
As long as the rotor has not been identified, it is not
possible to display RCF values. This is signaled by
dashes ----- in the display.
Shortly after starting the centrifuge run, the rotor is
identified and the current value is displayed.
NOTE:
If you set an extremely low RCF value, this may be
automatically corrected if the resulting speed would be
lower than 300 rpm.
