13 Entering
centrifugation
parameters
It is only possible to enter a parameter when the input field is displayed inversely (dark background). An
inverse input field will go off automatically after 10 seconds.
13.1 Running
time
13.1.1 Time
selection
•
Press the
t
key repeatedly until the parameter t/min: or t/ :sec is displayed. The input field will be displayed
inversely.
•
Set the desired value by means of the control knob .
13.1.2 Continuous
running
•
Select the parameters t/min: and t/ :sec one after the other (see Chapter "Time selection"), and set both to zero
using the control knob . "---:--" will be displayed in the input field.
13.2 Speed
(RPM)
•
Press the
n
key repeatedly until the parameter RPM is displayed and the input field is shown inversely.
•
Set the desired value by means of the control knob .
13.3 Relative centrifugal force (RCF/RZB)
•
Press the
RCF
key repeatedly until the parameter RCF/RZB is displayed and the input field is shown inversely.
•
Set the desired value by means of the control knob .
The centrifuging radius indicator will flash while the adjustment is being made.
13.4 Run-up and run-down parameters
The run-up and run-down parameters that have been set are displayed.
x: 1-9 = run-up step, t = run-up time
x
y
PROFIL
y: R1-R9, B1-B9 = braking step, R0 = unbraked run-down, t = run-down time, n
(•)
= brake de-
energisation speed
13.4.1 Run-up
step
•
Press the
key repeatedly until the parameter
1-9
or
t
is displayed. The input field will be displayed
inversely.
•
Set the desired step by means of the control knob .
13.4.2 Run-up
time
•
Press the
key repeatedly until the parameter
min:sec
t
is displayed. The input field will be displayed inversely.
•
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.
13.4.3 Braking
step
•
Press the
key repeatedly until the parameter
0-9
or
t
is displayed. The input field will be displayed
inversely.
•
Set the desired step by means of the control knob .
B-braking steps can only be set for special rotors.
13.4.4 Run-down
time
If a brake de-energisation speed has been set, it is not possible to set a run-down time.
•
Press the
key repeatedly until the parameter
min:sec
t
is displayed. The input field will be displayed inversely.
•
Set the desired value by means of the control knob .
