 [Setup]-[Settings]---[Gain]--WBC

• too small WBC gain that should be increased

• too large WBC gain that should be decreased.

 [Setup]-[Settings]---[Gain]--RBC

• When the difference between the actual MCV analysis result and the
expected result exceeds 6%, need to change the RBC gain.
• For example, assuming the expected MCV result is 90.0fL, while the
actual analysis result is 82.0fL, the gain factor as below:

ExpectedMCV 90.0
＝  1.098
ActualMCV 82.0
 [Setup]-[Settings]---[Gain]--HGB

• adjust the HGB gain to change the HGB blank voltage, which
usually should be set between 4.3 ~ 4.5V.

• If your analyzer is to run 24 hours a day, you should perform

this procedure every 3 days.

• If you follow the shutdown procedure to turn off your analyzer

everyday, you should perform this procedure every week.

• To make sure this analyzer functions normally, every time the

accumulated analyzed samples reach 200, a dialog box will pop
up to remind the user to perform the Probe cleanser cleaning
procedure.
[Service]-[Maintenance]—Lyse test

“Lyse test” is to check the injected volume for lyse is correct or not. W
hen shall we use this function?
When the WBC result or its histogram is abnormal, we should run this f

[Service]-[self-test]—[Test tubing]
Count Time WBC （ S ） & Count Time RBC （ S ）
It measures the duration of a WBC or RBC count
Aperture(v)
It measures the voltage (v) over the aperture.
Vacuum
It checks whether the vacuum system functions normally.
Pressure
It checks whether the system flushes the aperture at a normal press
ure.
Filter
It checks whether the filter functions normally.
[Service]-[self-test]—[Machine]
[Service]-[self-test]—[Valve]
[Service]-[self-test]—[Circuit]
It is to monitor that WBC, RBC and PLT signals can be properly converted
into digital signals or not.
[Service]-[Log]

The recorded events are divided into four groups, All, Para set, Error and Other
(including setting discriminators, system self-test and updating system software)

This analyzer can

save maximum 100
log files and once
the maximum
number has been
reached, the newest
log will
automatically cover
the oldest one.
