"RpM/g", "oC" or "TIME" are pressed the displays show
to indicate the start of setting modus. Quitting the setting modus will
not activate the points.
- Immediately after switching on the centrifuge displays "br.."
and startes to brake. Why this?
The centrifuge was previousely interrupted while centrifuging or braking
- maybe by failure of power. On next startup it performs at first a
noninterruptable brake (for security). This takes about 30 seconds. After
that the lid can be opened.
- Which speed is requested for the customary analyses?
For Gerber - method set the speed to 1100 RpM.
For method according to Roese - Gottlieb (Mojonnier tubes) set the
speed to 600 RpM.
For ADMI - methode set the speed to 900 RpM.
That values are valid only in connection with the appr. heads:
*Head A for Gerber / 1100 UpM
*Head B for Roese-Gottlieb / 600 UpM
*Head C for det. of solutibility / 900 UpM
The main point in centrifuging is the effective RCA (Relative
Centrifugal-Acceleration). This depends not only on the speed, but also
on geometric properties, on kind and dimension of the used head.

5.Tabular summary on Relative Centrifugal Acceleration
Notice:
The tolerance values refer to the empty and full loaded head, (A/B/C respectively) and a supply
voltage of 230 volt.
