8.3.2. 5DIFF Matrix thresholds
Each axis of the matrix (X and Y) is divided into 128 channels numbered from 0 to 127.
13 (Y) vertical indices and 13 (X) horizontal indices will allow the user to locate these chan-
nels by multiples of 10. The first index channel of the 5-Diff matrix is the origin (at the
bottom left corner). This is the «0» channel. The second channel will be 10, the third channel
will be 20, the fourth channel will be 30, and so on. The threshold adjustments are expressed
in channels.
Fig. 5–37 Matrix thresholds
There are only 3 basic reasons to adjust the matrix thresholds. (see 8.1.3. Modifying limit/
Alarm values, page 5-34):
a – To improve the separation between different cell populations which may vary according
to the selection of anti-coagulant for blood sample collection or minor internal instru-
ment adjustments.
b – To modify the alarm areas of these cell populations for improvement in detection sen-
sitivity.
c – To modify one or more matrix areas in order to define a more precise measurement of
a specific cell population for research purposes.
