4.4 TUBE CENTRIFUGATION
With the tube holders and hematocrit tubes in place, lock the lid by firmly pressing
down on the lid tab. Start the run cycle by pressing the RUN button. The centrifuge
will not operate unless the lid is closed and properly locked. If the RUN button is
pressed without locking the lid, the message LOCK LID will appear on the LCD.
Do not lean on the instrument.
During the period of time when the motor is accelerating, a test number is displayed
on the LCD. This number is a count of the completed spin cycles. Within seconds
the centrifuge
will reach the proper operating speed and the rpm will be displayed on
the LCD during the cycle. The LCD will display a countdown of time for the
remainder of the run cycle, and the device will stop automatically after 60 seconds.
When the run cycle is completed, an automatic braking system will engage to
completely stop the rotor. An audible tone will indicate that the spin cycle is
complete and the automatic lid lock will disengage to allow the lid to be opened.
