•
Manometer 0 to 4 bar (art. no. 7701357)
•
Flow meter (art. no. 770085A or equivalent)
•
Allen key 3 mm
•
Size 7 spanner
Please ensure that the manometer and connection tubing are at the same
level as the nonreturn valve during calibration.
1.
Connect manometer and flow meter between flow pump
FPA
and
FBK2
.
2.
Immerge both dialyser couplings into a vessel filled with warm water (30
to 40 °C). Thus uncontrolled pressure conditions are prevented.
3.
Select Test 1.20 Water Part (Overview) in TSM.
4.
Increase slowly the speed of
FPA
, until a flow of 500 ml/min is reached.
5.
Set temperature
TSD
to 37
o
C and wait for the temperature reached.
6.
Clamp tubing between manometer and
FBK2
.
7.
Loosen lock nut on
RVFPA
adjustment screw.
8.
Set a pressure of 975 mmHg (1300 mbar) with the adjustment screw of
RVFPA
.
