• Features: The viewer can intuitively see the size of the
particles from the size distribution.
If the particle size distribution strays from the
normal range, the viewer knows instantly that the
particle size distribution pattern is abnormal.
• Displays supported:RBC and PLT particle size distributions
if settings are preset to normal range
11. Main Unit electrical system
The microprocessor in the Main Unit controls solenoid valves
and master valves in the hydraulic system, thus, it controls the
flow of the sample, reagents and waste fluid in the hydraulic
system.
The electrical signals received from each detector are
processed (waveform processing) at the analog unit and sent
to the microcomputer unit. The microcomputer unit converts
the analog signals into digital signals, then computes the
results.
RBC and PLT cell signals are sent to the applicable waveform
processing circuits of the analog unit, where noise is
eliminated and the required blood cell signals are picked up.
The microcomputer unit converts the analog-to-digital-
converted cell signals into particle size distribution data and
sends the data to the IPU.
The RF- and DC- signals are sent to the applicable waveform
processing circuits of the analog unit, where noise is
eliminated and the required blood cell signals are picked up.
The microcomputer unit converts the analog-to-digital-
converted cell signals into scattergram data and sends the
data to the IPU.
HGB is calculated by subtracting the light absorbance of the
diluent (background count) from the light absorbance of the
sample. The light that is passed through the liquid in the
hemoglobin flow cell is received by the photodiode, where it is
photoelectrically converted. It is then converted from analog
to digital signals, and sent to the IPU.
