perform a function check of the blood leak
detector.
3.
Rinse the blood leak detector for approx. 1
min at the beginning of the rinsing time
with flow pump outlet
FPA
(approx. 1400
rpm). Thereby possible air bubbles in the
system are removed.
4.
Rinse blood leak detector for approx. 15 to
30 min with
FPA
(approx. 1000 rpm) to
warm up the complete system to a

LAMP TEST RED key to switch to the green LED. The RED key
switches to the GREEN key.
The green LED is tested. The controller value for the switched off green
LED must be as follows (the supervisor value is uncritical):
green LED
Actual Status Controller
Blood Concentration
> 2.06
7.
The actual controller values for the red LED and the green LED must be
divided.
Note:
The calculated value of
red LED
divided by
green LED
is displayed
briefly after the key LAMP TEST is switched back to OFF.
The calculated value must be in the following limits (to the first decimal
digit/round off):
red LED / green LED
1.15 - 1.44
