■
Setting the individual parameters.
Turning anticlockwise decreases the value.
Turning clockwise increases the value.
■
Switch the device on and off.
■
Ramp-up levels, parameters
Level 9 = shortest ramp-up time, Level 1 = longest ramp-up time.
■
Ramp-up time, parameters
Adjustable in 1 second increments.
■
Brake levels, parameters
1-9 = Linear braking curve
Level 9 = shortest ramp-down time, ...Level 1 = long ramp-down time,
Level 0 = unbraked ramp-down.
■
Ramp-down time, parameters
Adjustable in 1 second increments.
■
Brake cut-off speed, parameter N Brake
Adjustable from 50 RPM to the maximum rotor speed (N
ments of 10. Unbraked ramp-down takes place after reaching this
speed.
■
Start centrifugation run to pre-cool the rotor (only for devices with
cooling).
■
Centrifugation run, for pre-cooling of the rotor, takes place automatically
with the PREC program (PRECOOLING).
■
Retrieve programs and program links, parameter RCL (Recall).
Programs: Program locations 1 to 99. Program links: Program locations
A to Z.
■
Save programs and program links, parameter STO (Store).
99 programs can be stored (program locations 1 to 99).
Program location 0 serves as a buffer for the centrifugation data of
the last centrifugation run. No programs can be stored in this program
location.
25 program links can be stored (program locations A to Z, program
location J does not exist). A program link can consist of 20 programs.
■
Link programs, parameter EDIT.
■
'Machine Menu' .
Open the
■
Scroll forward in the menus.
■
Relative centrifugal force, parameter RCF.
The RCF is displayed in brackets ñ á.
A numerical value can be set that gives a speed between 50 RPM and
the maximum rotor speed (Nmax).
Adjustable in 1 second increments.
■
Centrifuging radius, parameter RAD.
Adjustable from 10 mm to 330 mm, in 1 millimetre increments.
