Calibration of Delivery Rate
UFP, BICP and KP
You can calibrate the ultrafiltration pump
UFP
, the bicarbonate pump
BICP
and the concentrate pump
KP
. The
BICP
and
KP
can be calibrated either with a
volumetric flask/graduated cylinder or a balance. The calibration with a balance
is mandatory for
UFP
. Prior to calibration the balance chamber initialisation
must be completed. The respective pump runs for approximately 2 minutes
after pressing the
key and stops after a certain number of
revolutions are reached.

During the selection of the menu:
•
the balance chamber is initialised and
•
the
UFP
is set to a defined initial position
(reed sensor/hall sensor position).
Thus the accuracy during the calibration of
UFP
is
improved, because
UFP
runs back to the initial
position at the end of calibration. Thus complete
revolutions are counted.
1.
Activate the LL Manual Calibration menu with
the LL Manual Calibration key in the Manual
Test and Calibration menu.
2.
Activate the Flow of BICP, KP and UF Pump
menu by pressing on the line Calibration 2.8
Flow of BICP, KP and UF Pump. The following
menu is displayed.
4.8.3.11.1 Calibration BICP and KP Pump
Prior to calibration the initialisation of the balance chamber must be
completed. The initialisation is completed, if the LLC Status window changes
from 0 0 0 0 0 0 0 0 4 to 0 0 0 0 0 0 0 0 0 .
The system must be free of air for calibration. Thus an accurate calibration is
guaranteed.

Balance or graduated cylinder
•
Tubing clamp
1.
Fill graduated cylinder with 200 ml water.
2.
Remove respective concentrate suction rod from rinsing chamber and
immerge into graduated cylinder.
