3.4.3 Positive Identification (PosID)
What Is PosID? The PosID (positive identification module) reads barcodes on carriers and
containers e.g. sample tubes, microplates, etc.
Performance
Data
The PosID is able to read horizontal and vertical barcodes.
ATTENTION
Barcodes cannot be read due to the influence of strong light sources (direct
sunlight, artificial lighting, etc.).
 Make sure that the PosID is not exposed to direct sunlight.
 Do not install strong light sources near the PosID.
Reading
Characteristics
The following typical read and detection rates can be expected:
Tab. 3-12 General PosID performance data
Number of different container code types per application Up to 6 different container code types can be
used at the same time
Reading positions on carrier Up to 24 container positions
Max weight of a carrier to be handled by PosID 2.2 kg (4.85 lbs)
Immunity against external light sources External light below 8000 lux is harmless
Work range for carriers (clear worktable, i.e. no elements, such as
incubators that restrict the PosID access range, present) The PosID can read the carrier ID in any grid
position
a)
Work range for containers on the worktable (clear worktable, i.e. no
elements, such as incubators that restrict the PosID access range,
present) Restriction: The PosID cannot read the con-
tainer IDs of carriers in the two rightmost grid
positions
a)
Throughput: Required time to read 10 strip racks (16 positions) Max. 90 s (including carrier ID)
a) Restrictions due to additional elements on the worktable, e.g. incubators.
