Relative centrifugal force (RCF) and centrifuging radius (RAD)
Relative centrifugal force (RCF) depends on the centrifugal radius (RAD). Before RCF is set, the centrifugal
radius has to be set.
Press the
RCF
key as often as is required until the parameters
RAD
and
RCF
are displayed and the value of
the parameter,
RAD
is displayed in parentheses,
e.g.
RAD =
146
RCF = 3695
. The LED is lit in the key.
Use the adjusting knob to set the centrifuging radius you want.
By changing the centrifuging radius, the value adjusts automatically to the RCF.
Press the
RCF
key again. The value of the parameter,
RCF
is displayed in
parentheses, e.g.
RAD = 146
RCF =
3695
.
Press the
PROG
key to save the set RCF value. See the "Inputting or changing programs" chapter.
Press the
RCF
or
START
keys to apply the setting to the display.
Only by storing (STO) the set RCF value will the RPM value resulting from that be accepted.

Start-up and run-down parameters
The set start-up and run-down parameters are displayed.
x:
1-9 = start-up stage, t = start-up time
x
y
y:
1-9 = braking stage, 0 = unbraked run-down, t = run-down time
18.5.1 Start-up
stage
and start-up time
It is only possible to set start-up times if these have been activated. See the chapter "Activating or deactivating
start-up and run-down times".
Press the
key. The parameter
or
t
is displayed.
= start-up stage,
t
= start-up time
Press the
TIME
key to switch between the start-up stage and start-up time.
Set the desired stage or time with the rotary knob .
If necessary, press the
key to set the next parameter.
To apply the setting to the display, either press the
START
key or press the
key as often as is required until
the centrifugation data are displayed.
18.5.2
Braking stage and run-down time
No B-brake stages can be set for this device. The activation of the B-brake stages in the "Settings" menu is
not possible (parameter
B-Ramp = off
). B-brake stages are similar to an exponential braking curve.
It is only possible to set run-down times if these have been activated. See the chapter "Activating or
deactivating start-up and run-down times".
Press the
key until the parameter
or
t
is displayed.
= braking stage,
t
= run-down time
Press the
TIME
key to switch between the braking stage and run-down time.
Set the desired stage or time with the rotary knob .
If necessary, press the
key to set the next parameter.
To apply the setting to the display, either press the
START
key or press the
key as often as is required until
the centrifugation data are displayed.
18.5.3
Brake switch-off speed
Press the
key as often as necessary until the parameter
N Brake
is shown.
Use the adjusting knob to set the value you want.
Press the
or
START
keys to apply the setting to the display.
