10.6.3.1. Zero Offset of Blood Leak Sensor
The blood leak sensor needs to be offset to zero when the value of “6. BLD AUTO ZERO” on the
maintenance mode 1 screen becomes less than -150ppm in the standby process.
ܭ
CAUTION
z Check the value after removing stains fully by water rinsing and chemical rinsing. Offsetting
with any stains may cause deviation of blood leak detection value.
(1) The standby process can be started only in a properly rinsed status.
(2) Turn the adjustment volume 1 to the left in 5 minutes or more in the standby process.
Adjust the volume until “6. BLD AUTO ZERO” becomes within “-40 through -30ppm”.

Adjustment volume 1
(*1) Check that there is no air bubble in the cartridge of the blood leak sensor during zero
offset.
(*2) Do not turn the volume excessively in the zero direction of “6. BLD AUTO ZERO”.
Doing so may display a value slightly lower than the actual blood leak value.
