3 System Principles 3.1 Introduction The analyzer uses the electrical impedance method to determine the count and size distribution of RBC, WBC and PLT; and uses the colorimetric method to determine HGB. Based on the above data, the analyzer calculates other parameters.
3.2 Analyzer Workflow We have defined the whole operation workflow of the analyzer by its major functions: reagent system, sample loading and distribution, sample preparation, sample measurement, signal processing, parameter analysis, status monitoring, scheduling control and information processing, man-machine interface, power as well as cleaning and maintenance. The relationships between the functions are illustrated as below:
The scheduling control and information processing module coordinates and regulates other functional modules to work by defined process and requirements, so as to ensure the completing of sample measurement, the ultimate task of the analyzer.
3-1
System Principles
3.3 Aspiration If you are to analyze a whole blood sample, present the sample to the analyzer directly, and the analyzer will aspirate 9 μL of the whole blood sample. If you are to analyze a capillary blood sample under the pre-dilute mode, you should first manually dilute the sample (20 μL capillary sample needs to be diluted by 0.7 mL of diluent to form a 1:36 dilution), and then present the pre-diluted sample to the analyzer, which will aspirate 198uL of the sample.
3.4 Dilution Usually in blood samples, the cells are too close to each other to be identified or counted. For this reason, the diluent is used to separate the cells so that they draw through the aperture one at a time as well as to create a conductive environment for cell counting. Moreover, red blood cells usually outnumber white blood cells by 1,000 times. Because red blood cells usually have no nucleus, they are eliminated when the lyse breaks down their cell walls. For this reason, lyse need to be added to the sample to eliminate the red cells before the WBC counting. The analyzer provides whole blood mode and predilute mode for the analysis of different sample types.
3.5 WBC Measurement 3.5.1 Measurement Principle: WBC measurement principle
The WBCs are counted by the impedance method. The analyzer aspirates certain volume of sample, dilutes it with certain volume of conductive solution, and delivers the dilution to the metering unit. The metering unit has a little opening which is called "aperture". A pair of electrodes is positioned on both sides of the aperture, and creates a constant-current supply. As cells are poor conductors, when each particle in the diluted sample passes through the aperture under the constant negative pressure, a transitory change in the direct-current resistance between the electrodes is produced. The change in turn produces a measurable electrical pulse which is proportional to the particle size. And when the particles pass the aperture in succession, a series of pulses are produced between the electrodes. The number of pulses generated indicates the number of particles passed through the aperture; and the amplitude of each pulse is proportional to the volume of each particle. Each pulse is amplified and compared to the internal reference voltage channel, which only accepts the pulses of certain amplitude. All the collected pulses are thus classified based on the reference voltage ranges of different channels, and the number of the pluses in the WBC channel indicates the number of the WBC particles. The cell size distribution width is represented by the number of particles falling in each channel.

System Principles
Figure 3-1 Metering diagram
3.5.2 WBC-Related Parameters White Blood Cell count
WBC (109/L) is the number of leukocytes measured directly by counting the leukocytes passing through the aperture. Sometimes there are nucleated red blood cells (NRBC) presenting in the sample. While the lyse will not be able to break their nuclear membrane, these NRBCs will also be counted as WBCs. Therefore when NRBCs are found during microscopic exam, follow below formula to modify the WBC count:
In the formula, WBC′ is corrected WBC count result; WBC is the WBC count provided by the analyzer; and NRBC indicates the number of NRBCs found when every 100 WBCs are counted.
3-DIFF of WBC
Lyses and diluents change the sizes of each type of WBCs in various ways and at different time. The WBCs are thus separated into 3 parts (from the largest size to the smallest): lymphocytes, mid-sized cells (including monocytes, eosinophils, and basophils) and granulocytes. The analyzer then calculate the lymphocyte percentage (Lym%), mid-sized cell percentage (Mid％) and granulocyte percentage (Gran%) (All presented in %) based on the WBC histograms and in accordance with below formulae:
3-3
System Principles
In the formulae: PL indicates the number of cells falling in the lymphocyte region, PM the number of cells falling in the mid-sized cell region, and PG the number of cells falling in the granulocyte region. All three parameters are presented in 109/L. When the three percentages are obtained, the analyzer automatically proceeds to calculate the lymphocyte number (Lym#), mid-sized cell number (Mid#) and granulocyte number (Gran#) by below formulae , all parameters expressed in 109/L.
Lym％, Mid％ and Gran％ are expressed in %, while WBC is in 109/L. White blood cell histogram
Besides the count results, the analyzer also provides a WBC histogram which shows the WBC size distribution, with the x-axis representing the cell size (in fL) and the Y-axis representing relative cell number (in 109/L)(as shown below). The WBC histogram of a normal blood sample (lysed and processed) should show display 3 clear parts: the small cell (about 20~70fl) region represents the LYM group (lymphocytes); the mid-sized cell (about 70~150fl) region represents the Mid group (including monocytes, eosinophils and basophiles); and the large cell (over 150fl) region represents the Gran group (granulocytes).

System Principles
After each analysis cycle, you can either check the WBC histogram in the analysis result area on the "Sample Analysis" screen or review the histogram on the "Review" screen.
3.5.3 HGB Measurement The HGB is determined by the colorimetric method. The diluted sample is delivered to the WBC count bath where it is bubble mixed with a certain amount of lyse, which breaks red blood cells, and converts hemoglobin to a hemoglobin complex. An LED is mounted on one side of the bath and emits a beam of monochromatic light with 530~535nm central wavelength of 530~535nm. The light is received by an optical sensor mounted on the opposite side, where the light signal is first converted to current signal and then to voltage signal. The voltage signal is then amplified and measured and compared to the blank reference reading (reading taken when there is only diluent in the bath), and the HGB (g/L) is measured and calculated automatically. The whole measurement and calculation process is completed automatically. You can review the results in the analysis result area on the "Sample Analysis" screen. HGB is expressed in g/L.
Blank Photocurrent HGB(g/L) = Constant × Ln Sample Photocurrent
3.6 RBC/PLT Measurement 3.6.1 Impedance Method RBCs/PLTs are counted by the electrical impedance method. The analyzer aspirates certain volume of sample, dilutes it with certain volume of conductive solution, and delivers the dilution to the metering unit. The metering unit has a little opening which is called "aperture". A pair of electrodes is positioned on both sides of the aperture, and creates a constant-current supply. As cells are poor conductors, when each particle in the diluted sample passes through the aperture under the constant negative pressure, a transitory change in the direct-current resistance between the electrodes is produced. The change in turn produces a measurable electrical pulse which is proportional to the particle size. And when the particles pass the aperture in succession, a series of pulses are produced between the electrodes. The number of pulses generated indicates the number of particles passed through the aperture; and the amplitude of each pulse is proportional to the volume of each particle. Each pulse is amplified and compared to the internal reference voltage channel, which only accepts the pulses of certain amplitude. All the collected pulses are thus classified based on the reference voltage thresholds of different channels, and the number of the pluses in the RBC/PLT channel indicates the number of the RBC/PLT particles. The cell size distribution width is represented by the number of particles falling in each channel.

4.3 Calibration 4.3.1 Calibration Factors Calibration is performed to ensure the analyzer may deliver accurate sample analysis results. During the calibration process, a calibrator factor will be calculated. This factor will be used to multiply with the analysis results to output the final results. When running a calibrator, the analysis results after being adjusted by the factor should be as close to its assigned targets. Thus the calibrator factor is derived by below formula:
Calibration with fresh blood includes two modes of "WB" and "PD", which use different fluidic sequences. Perform calibration for each of the two modes separately. Besides the calibration factor of the manufacturer, the factor of the users is also used to calculate the results. For example ,under the CBC+DIFF mode, the final analysis results output by the analyzer are calculated as follow:
Only the 5 traceable parameters are used in the calibration including: WBC, RBC, HGB, MCV and PLT. 4-4
Software and Interface
CAUTION When you perform calibration at the service access level, the calibration factors of manufacturer will be modified, and the calibration factors of user will change to 100.00%.
4.3.2 Calibration with Calibrator
Figure 4-5 Calibration at Service Access Level When performing calibration with calibrator at service access level, the analyzer calculates all factory calibration factors automatically. You need to run at least 5 calibrations to calculate and save calibration factors.

Figure 4-7 Temperature Calibration As you can see from the figure above, four values are displayed on this screen, namely Total difference, New difference, Machine measurement value and Meter measurement value. Machine measurement value refers to the temperature displayed on the "Temp & Pressure screen", while the "Meter measurement" displays the temperature measured by thermograph. "Total difference" and "New difference" are calculated values. However, the real measured value, which is measured by the temperature sensor, is also used but not displayed.
Enter the "Meter measurement" value and tap "Calculate new diff." to get the new difference. New difference = Meter measurement – Real measurement Tap "Save" to assign the new difference value to the "Total difference", e.g., Total difference = New difference. Machine measurement = Real measurement + Total difference
4.6 Gain Calibration The function is used to calibrate the gains for the RBC, WBC and HGB parameters, including MCP, WCP, HGB, RBC effective width and WBC effective width. The purpose is to ensure each channel may deliver reliable results.

Software and Interface
Figure 4-8 Gain Calibration
You can calibrate the gain factors for all parameters displayed above at the same time. Among the parameters, the WBC/RBC effective width is calibrated by software with averaging method. Tap the "Select" boxes to select the results used to calculate the mean values. WCP, MCP and HGB gains instead are hardware gains and calibrated with successive "approximation method". They are not affected whether any group of results is "selected". Invalid calibration results will be displayed in red. In this case, do the calibration again. If the target of a parameter is not set, the parameter will not be calibrated (like MCP on above figure). The system will ask if you want to save the calibration factors when exiting the Gain Calibration screen.
CAUTION The function only supports the calibration with calibrators. Never use expired calibrators. Refer to the calibrator target sheet provided manufacturer.
4.7 Gain Setup You can set up the gain for HGB on the "Gain Setup" screen. Gains for other parameters are obtained by gain calibration and cannot be edited.

2-way valve
3-way valve
Appearance:
2-way valve
3-way valve
Spring pole Function: 2-way valve: to build up or cut off a passage. When power off, the passage from the inlet of the valve to outlet is cut off; when power on, the passage is built up. 3-way valve: to switch among passages. When power off, the public end and the NO (normally open) end are connected; when power on, the public end and the N.O.(normally open) end are connected. Note: the operating voltage of Mindray valves is 12V, and maximal bearable pressure is 200KPa. The internal movement of the valves is driven by electromagnet and the restoration is driven by the spring, so it is recommended not put the valves power-on for too long. When the electromagnet valve is working, the spring pole will lower down, and it will rise to the initial position when power off. You can touch the spring pole and feel the descending or ascending, in order to determine whether it is in action.

6.2 Sample Dilution Flow Chart 6.2.1 Whole Blood Mode Compared to old models, the analyzer adopts a "single aspiration" method for whole blood analysis. The basic procedure is as follows: 1) The sample probe aspirates 9uL of sample blood and ascends. In the meanwhile, the exterior wall of the sample probe is cleaned. 2) Dispense the initial volume and 9uL of sample to the WBC bath, where they are well mixed to prepare the diluted sample for WBC and HGB measurement. 3) The sample probe ascends. In the meanwhile, its exterior wall is cleaned. Where the sample probe ascends to the probe wipe, it dispenses some of the diluent in it to clean its interior wall. 4) The sample probe whirls descending to the RBC bath, and dispenses initial volume to the bath. 5) The sample probe whirls descending to the WBC to aspirate 23.1ul of diluted sample and then dispense the sample and additional diluent to the RBC bath. In the meanwhile, additional diluent is added to the RBC bath. The further diluted sample is used for RBC/PLT count. 6) Add and mix lyse to the WBC bath for reaction; 7) Run the analysis; 8) When the analysis completes, clean the WBC and RBC baths, zap the apertures, and release the vacuum pressure. The dilution procedure under whole blood mode is illustrated Figure 6- 1 as below:
6-7
Fluidics
Figure 6- 1 Dilution under whole blood mode
6.2.2 Predilute Mode The analysis under predilute mode contains 3 function-based sequences: diluent dispensing sequence, cleaning (open-vial) sequence and analysis sequence. The basic procedure is as follows: 1) Sample probe dispenses 700uL of diluent to the centrifugal tube. Then use a capillary tube to add the 20uL of sample blood to the centrifugal tube. Well mix the sample. 2) Sample probe aspirates and dispenses 198uL of the prepared sample to the WBC bath. Add diluent to the bath to fairly mix with the sample for WBC and HGB measurement. 3) Sample probe ascends. Its interior and exterior walls are cleaned. 4) The sample probe descends to the WBC to aspirate 37.7ul of diluted sample and then dispense the sample to the RBC bath. In the meanwhile, additional diluent is added to the RBC bath. The further diluted sample is used for RBC/PLT count. 5) Add and mix lyse to the WBC bath for reaction; 6) Run the analysis; 7) When the analysis completes, clean the WBC and RBC baths, zap the apertures, and release the vacuum pressure. You can see the analysis procedures under whole blood and predilute modes are basically the 6-8
Fluidics same except for the sample aspiration procedure and the sample dispensing procedure to WBC bath. The dilution procedure under predilute mode is illustrated Figure 6- 2 as below:

6.3 Introduction to Fluidic Channels 6.3.1 WBC/HGB channel Reagent used: 1) M-30PCFL cyanide-free lyse (break out RBCs and PLTs and 3-differentiate WBCs based on cell size); 2) M-30PD diluent (used for cleaning, and providing appropriate environment for reaction and measurement) Measurement principle: impedance method (for WBC count); colorimetric method (for HGB measurement) Measurement parameters: WBC and HGB Output graph: WBC histogram Dilution ratio: 1：305.2 (whole blood mode); 1：500.8 (predilute mode) Aperture diameter: 100um 6-9
Fluidics
Sample volume needed: 400μl; analysis time: 10s Function description: 9ul blood sample and 1.55ml diluent are mixed in the WBC bath to get diluted sample; of which 23.1ul is dispensed to the RBC bath, and mixed 0.31ul of lyse. The sample solution after full reaction is then sucked into the back bath by vacuum pressure in the vacuum chamber. The cells are counted when they pass the aperture. Sample volume is calculated based on analysis time.
6.3.2 RBC/PLT channel Reagent used: diluent (dilution, cleaning, providing conductive environment and processing cell sizes) Measurement principle: impedance method Measurement parameters: RBC and PLT Graphics: RBC histogram; PLT histogram Dilution ratio: 1：16497.3 (whole blood mode); 1：16445.7 (predilute mode) Aperture diameter: 70um Sample volume needed: about 200μl; analysis time: 10s Function description: sample probe aspirates 23.1ul of the diluted sample (dilution rate: 1：173.22) from the WBC bath, and dispenses the sample as well as additional diluent to the RBC bath, where the sample and the diluent are further mixed with existing initial volume of diluent (in all 2.2 ml diluent is used in this process) to get a dilution of 1：16497.3. After full mixing and reaction, the sample solution is then sucked into the back bath by vacuum pressure in the vacuum chamber. The cells are counted when they pass the aperture. Sample volume is calculated based on analysis time.

Analysis Procedure
After the sample aspiration and dispensing procedure, the analysis will start. See Figure 6-4 for the procedure. Build in the vacuum chamber a -30KPa vacuum which presses the sample solution in the front baths of WBC and RBC baths to flow through the apertures to the back baths. The sample solution in both the two back baths will then flow to the vacuum chamber in the direction indicated by the red arrows.
Figure 6-4 Analysis Procedure
6.7.1.3
Cleaning Procedure
As the analyzer only has two baths, the cleaning procedure is comparably simple : 1. Empty and prime the WBC bath; 6-14
Fluidics 2. Zap apertures, clean the back baths; 3. Empty and prime the RBC bath; 4. Clean the back baths again; 5. Empty and prime the WBC bath.
6.7.2 Analysis Sequence under Predilute Mode Analysis sequence under predilute mode for a large part is the same as that of whole blood mode except for sample and the diluent consumption.
6.7.3 Introduction to Major Maintenance Sequences 6.7.3.1
Probe Cleanser Maintenance (Shutdown Sequence)
The probe cleanser maintenance during the shutdown process involves the following parts: the front and back baths of WBC and RBC baths, back bath tubing, sample probe as well as sampling tubing. The analyzer will perform "enhanced" probe cleanser maintenance after every 300 analyses. Compared with normal probe cleanser maintenance, the enhanced process uses a longer probe cleanser soak time (1 minute longer than normal maintenance). Tap "Fluidic" on the "Maintenance" screen, the analyzer will perform enhanced probe cleanser maintenance.
6.7.3.2
Cleaning Procedure during Startup
The fluidic actions during the startup consist of the following parts: 1 Initialization of fluidic components: initialize the aspiration module and syringe module, build and release vacuum. 2 Overall cleaning: clean all the tubes, parts and components of the analyzer. Remove bubbles in the diluent preheating bath. No lyse is consumed. 3 Background check: under whole blood mode. If the background does not pass, the analyzer will perform the overall cleaning procedure one more time, and then check the background again. When the analyzer starts after abnormal shutdown, it will perform the overall cleaning procedure twice.
6.7.3.3
Standby
The analyzer enters "Standby" mode when there is no action perform for 15~30 minutes
6-15
Fluidics (configurable, 15 minutes by default) When the analyzer is standby, you can still perform operations not involving fluidic actions. Exit standby status1: standby for less than 1 hour Clean the exterior wall of sample probe and WBC bath, re-build isolation bubbles. The process does not consume lyse. Exit standby status1: standby for more than 1 hour, but no longer than 3 hours. Clean both the exterior and interior walls of sample probe, clean the WBC and RBC baths, re-build isolation bubbles. The process does not consume lyse. Exit standby status3: standby for more than 3 hours, but no longer than 12 hours. Equivalent of overall cleaning; all the tubing, parts and components will be cleaned, remove bubbles in the diluent preheating bath, remove the crystallization and bubbles at the diluent inlet. Exit standby status4: standby for more than 12 hours. Base on Exit standby status3, increase to remove bubbles in lyse tubing.

7.4.2 Power Board Replacing and Wiring The power board plays a very important part in the device, and any error with the board may endanger the operation of the whole. Follow below steps to replace the power board when needed: Tools: 107 cross-headed screwdriver, multimeter. Disassembly: 1. Shut down the analyzer and pull out the AC cables; 2. Take out the power assembly from the main unit case; 3. Open the power unit, remove the 4 fixing screws on the power board, and take out the board from the power unit.
WARNING Wear an antistatic wrist strap while removing the board; Always shut down the power and pull out the power cable before removing the board. Installation: Install the power board in the reversed order of the disassembly steps. Check: 1. Check whether all the screws on the board are properly fixed; 2. Connect the power cable, and turn on the AC switch. The analyzer starts its initialization, and all the indicators on the board light on.
7-10
Hardware System
CAUTION Ensure the power unit is tightly fixed to the main unit case with screws. Before disassemble the power board, ensure the power board and its peripherals have cooled off.
7.5 Touch Screen Control Board 7.5.1 Introduction As the interface between the touch screen and the main control board, the touch screen control board transfers the touch actions from the users to recognizable signals by main control board. You may need to make some adjustment to the touch screen control board during use.
7.5.2 Components With the 4-wire touch screen controller chip TSC2004IRTJR as its core chip, the board communicates with the main control board about touch point positions through an I2C interface.
Figure 7-6 Connection of touch screen
7.6 Indicator Board 7.6.1 Introduction The indicator board informs about the working status of the analyzer by sending out sounds and lights.
7-11
Hardware System Figure 7-7 Indicator board
7.6.2 Components The indicator board consists of a three color indicator (red, yellow and green) with its control circuit as well as the buzzer drive circuit. You do not need to make adjustment to the indicator board during use.
7.7 Motors, Photocouplers and Micro-switches 7.7.1 Introduction Motors drive the aspiration module and syringe module etc.; photocouplers detect the motor movements; and micro-switches are used to start analysis process. See below for the illustrations of motors and photocouplers.
7.8 Liquid Detection Board 7.8.1 Introduction The liquid detection board detects whether there is liquid in the tubes by monitoring the index of refraction. 7-12
Hardware System
Figure 7-8 Liquid detection board
7.8.2 Components The most important components of the board are the photocouplers. There is an LED indicator on the back of the board, which will light off when the photocoupler is blocked between its transmitting and receiving tubes, and light on when the photocoupler is blocked. You can use a piece of paper to block the photocoupler and check whether the board is working properly.
7.9 Hardware Troubleshooting 7.9.1 System Error Hardware system errors mainly include board errors, cable errors and component errors. The subsequent sections should have provided troubleshooting methods for most of such errors; but when the power supply to the hardware system is abnormal (for example, the analyzer cannot be powered on, or would start self-protect mechanism immediately after being powered on), you need to start troubleshooting from the system level. Figure 7- 9 demonstrates the troubleshooting procedure for power supply errors. Figure 7-10 displays a filter locating at the lower part at the rear of the analyzer. The filter controls the power supply and frequency filtering of the analyzer.

7.9.2 Troubleshooting for Main Control Board Table 7-4 lists the errors commonly found on the main control board as well as their solutions. However, the list only includes hardware errors and sometimes software errors may cause similar problem. Also many errors need to be detected by software. Check the following items before troubleshooting the main control board: 1.
Check whether the cables connecting to the main control board get loose or insecure.
2.
Check whether the position no. marked on the cable correspond to the sockets there are connected to; and whether the cables are broken or damaged;
3.
Check whether the input power of sockets J4~J6 on the board are normal (measure the voltages with a multimeter; refer to "Definition of sockets" for the pin functions).
4.
Check whether the indicators on the main control board work properly against Table 7-2. When you have confirmed all the cables are properly connected, all the input power and
indicators work normally, follow the instruction in Table 7-6 for troubleshooting. Table 7-6 Troubleshooting for main control board No. 1
