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.

• 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.

[Service]-[self-test]—[Test tubing]

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.
