BC-2800 Specification
BC-2800 Installation---Environment
Environment
The environment should be as free as possible from dust, mechanical vibrations, loud
noises and electrical interference.
Avoid proximity to brush-type motors, flickering fluorescent lights and electrical
contacts that regularly turn on and off.
Avoid placing the instrument in direct sun or in front of a source of heat.
BC-2800 Installation---Space
Space
Comfortable working height
At least 40cm on each side is the preferred access to perform service procedures.
At least 10cm behind for cabling and ventilation
There is enough space for reagents.
BC-2800 Installation---Power
Power
A properly grounded socket supplying 220 or 110 volts
The fluctuation should be in the range of ±10%.
The power frequency should be 50/60Hz.
Power consumption is less than 180VA.
Select some samples in the sample tabular review menu, and then p
ress [F5] to access “extension function” menu.

Sample information input
1. Press [MODE] to select the prediluted mode (any mode preceded by PB). 2. Press [DILUENT] to enter the Add Diluent screen3. Prepare a clean sample cup under the sample probe and press [START] to dispense 1.6ml diluent to the cup.
4. Take out the sample cup after the sample probe rose up and press [ENTER] to exit the Add Diluent screen. 5. Collect 20μL capillary blood specimen and immediately add it to the sample cup and shake to mix them.
Preparation of pre-diluted blood
[F1] is to select the setting items.

• 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:

• 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.
“Lyse test” is to check the injected volume for lyse is correct or not. When shall we use this function?When the WBC result or its histogram is abnormal, we should run this function.
Screw off these two screws
[Service]-[Maintenance]—Lyse test
Remove the Count bath shield cover
The injected lyse must over the second mark
2ml lyse will be dispensed to the count bath.
[Service]-[Maintenance]—Lyse test
[Service]-[Maintenance]—Drain
• Drain bath
Empty the count bath, and prime it again
• Drain Tubing
Empty all tubing, then turn off the equipment
[Service]-[Maintenance]—Clean
• Clean bathUse diluent to clean count bath
• Clean wipe blockAfter being used for a long time, the bottom of the probe wipe
block may be contaminated by blood.
When the accumulated analyzed samples reach 4,000, a dialog box will
pop up to remind the user to clean the wipe block
[Service]-[Maintenance]—Prepare to ship
• Empty the tubing
• Wash the tubing
• Empty the tubing
• Turn off the equipment
[Service]-[System test]
The available self-test items are divided into four groups, the
Tubing, Machine, Valve and Circuit.

Count Time WBC( S) & Count Time RBC( S) It measures the duration of a WBC or RBC countAperture(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]
It is to monitor that WBC, RBC and PLT signals can be properly converted
into digital signals or not.
[Service]-[self-test]—[Circuit]
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.
