x: 1-9 = run-up step, t = run-up time
y: R1-R9, B1-B9 = braking step, R0 = unbraked run-down, t = run-down time, n(•) = brake deenergisation speed

 Set the desired value by means of the control knob .
If a run-up time is set that is longer than the running time, the centrifugation run will end before the set speed is
reached.

Brake de-energisation speed
Press the
key repeatedly until the parameter n(•)/RPM is displayed. The input field will be displayed inversely.

Radius/Temperature
14.5.1
Radius
 Press the key repeatedly until the parameter r/mm is displayed and the input field is shown inversely.
 Set the desired value by means of the control knob .
The value of the RCF/RZB adapts automatically when the radius is changed; this is shown by the indication flashing.

Temperature (for centrifuges with cooling only)
Press the key repeatedly until the parameter T/°C is displayed and the input field is shown inversely.
Set the desired value by means of the control knob .
14.6 Automatic buffer
The buffer comprises the program locations "----" and 90 to 99. Every time a centrifugation run is started, modified
centrifugation data are automatically stored in program location "----". The modified centrifugation data for the last 11
centrifugation runs are stored in the buffer and can be called up (see Chapter "Calling up programs").
