OPERATION PRINCIPLES
SPECIMEN TRANSPORT - HmX HEMATOLOGY ANALYZER
r
The bed resumes rocking.
t
The bar-code scanner reads the Cassette/ Position label and the tube label a second
time.
t
If both bar-code scans are identical, the Autoloader continues to rock and moves the
cassette until the next available tube has reached the piercing station.
t
If the bar-code scans are not identical, the Autoloader stops. No data is available for
the sample. The Autoloader continues sampling at the next available tube when
restarted.
r
This sequence continues until all tubes in the cassette have been sampled.
r
The Autoloader continues rocking and moves the cassette along the bed to the unloading
area.
r
Once the cassette has reached the fourth pierce position, the second cassette is lowered
and placed on the rocker bed.
