Optical line
sensor
Located on the right side of the MCS+ top deck is the optical line sensor which
monitors the blood components passing through the effluent tubing. This
measurement is important for the MCS+ software in controlling the final collec-
tion product.
Caution: The line sensor will not provide accurate readings if the optical lens is
obstructed in any way; thus the lens must be cleared of any extraneous substanc-
es to ensure proper functioning of the system.
Weigher
The “weigher” is the term used by Haemonetics to describe the MCS+ compo-
nent which measures in grams the contents of the collection container(s) placed
on the “weigher arm”.
When the Draw key is pressed to begin a procedure, the weigher will automati-
cally tare, or set the weigher to zero. Thus, the weight of the container will not
be included in the weight displayed on the MCS+ screen.
To ensure optimal accuracy from the weigher during a collection procedure:
!
The weigher arm must be fully extended, positioned at a 90 degree angle
to the MCS+ top deck, prior to the system self-tests.
! The collection container must hang freely, without any contact with the
MCS+ cabinet.

Caution: The operator must be careful to not touch the weigher once the weight
of the collection container has been set to zero. This could affect the collection
procedure and a warning will be provided to the operator.
