7. After Open the Light-Shield Cover
Normally, when the instrument is working, the cover should be closed in
advance, or else, the test can not go further. For Engineer, you can place the
Magnetic on the cover sensor to disable it. Or you can disconnect the sensor
cable and connect the Pin 1 and Pin3.
8. Instrument Requirement
1. Instrument has Inbuilt Main board inside. It doesn’t
need to have PC working with.
2. Online UPS is Necessary.
3.RAC-Cleanser and cuvettes should be original from
Rayto, or else, it will have the problem that the Probe
cannot wash totally and bring Carry-over contamination,
and the cuvette is not mixed properly, or even the optical
system cannot work properly.
9. RAC-Cleanser
RAC-Cleanser (30ml)
Expired Date: 12 Month
Expired Date after open: 30 Day

volume+20ul
10. Part 1 Instrument Principle
Principle of light-path
Electronic circuit principle
Liquid Path
16. Clotting/Coagulation Method
Scatter Light intersity refects due to the Turbidity Strength. And it’s Linear with
the Testing Material Concentration.
Wavelength: 660nm
No Filter inside, Only
Red Interference Plastic
17. PT Actual Reaction Curve
X axis: Time(s)*10, 200 means 20s
Y axis: AD, Max Value is 65535
Coagulation Time (S)
18. PT ratio= PT/Normal
INR= (PT ratio)^(ISI)
DFbg need to calibration with sample
PT% need to do calibration with blood pool
Note: For the Software V2.4e, the DFbg Unit is same with FIB.
19. Immunologic Method
Light resource is LED and there is 575nm filter in the
Optical System. It will produce yellow light
go through cuvette.
The Turdimitry is more intense, the less light
will transit through the Cuvette.

21. Chromogenic Method
Light resource is LED and there is 405nm filter in the
Optical System.
It’s Purple color in the Reaction cuvette. The
Turdimitry is more intense, the less light
will transit through the Cuvette.

30. Item Testing Workflow
• Temperature
Stabilized
Add Sample
• Incubate
Add R1
• Mix and Test
Or Incubate
Add R2
Note: If the Sample is need to predilution, the probe will add the
Diluent firstly and then add the Sample, After that, Dispense into
the cuvette and then add R1 and R2.
If sample dilution is not possible to complete in one time, it will
use one Cuvette to diluent the sample. After that, the probe will
add diluent and then add the diluted sample and dispense to the
new cuvette and further add R1 and R2
Test Cycle Time is
30 second
