Acoustic Signal; Relative Centrifugal Force (Rcf) - Hettich ROTOFIX 32 A Bedienungsanleitung

17

Acoustic signal

The acoustic signal sounds:

After a disturbance occurs, in 2 second intervals.

After completion of a centrifugation run and rotor standstill in 30 second intervals.
The acoustic signal is stopped by opening the lid or pressing any key.
The acoustical signal can be activated or deactivated as follows when the rotor is at a standstill:

Switch off the mains switch.

Keep the key beneath the speed indicator and the key

Switch on the mains switch and release the keys again.

Press the key beneath the speed indicator until the following display appears:
The acoustical signal setting is displayed on the time display.
0 = acoustical signal deactivated, 1 = acoustical signal activated.

With the keys below the time display, set 0 or 1.

Press the key to save the setting.

Relative centrifugal force (RCF)

The relative centrifugal force (RCF) is given as a multiple of the acceleration of gravity (g). It is a unit-free value and
serves to compare the separation and sedimentation performance.
These values are calculated using the formula below:
RCF
RCF = relative centrifugal force
RPM = rotational speed (revolutions per minute)
r = centrifugal radius in mm = distance from the centre of the turning axis to the bottom of the centrifuge
The relative centrifugal force (RCF) stands in relation to the revolutions per minute and the centrifugal
radius.
