1. Prepare blood samples for testing: collect blood samples of different blood types, which can be O, A, B and AB.
2. Connect the blood type detector: connect the sensor in the circuit to the 51 microcontroller to make sure the circuit is normal.
3. Import the test program: write the corresponding test program and import it into the 51 microcontroller.
4. Take a drop of blood sample: using a sterile needle or blood collection needle, take a drop of blood sample to be tested and place it in the test area.
5. Start the tester: Start the blood tester to begin testing by pressing the appropriate button or triggering the sensor.
6. Wait for the result: according to the designed program and algorithm, the 51 microcontroller will analyze the blood sample and show the test result on the display.
7. Check the accuracy of the result: the test result will be compared with the known blood type to confirm the accuracy.
For the reasons of testing blood typing tester, it can be expanded in the following aspects:
1. Ensure that the instrument is functioning correctly: The test is to verify that the design of the blood typing tester meets the expected functional requirements, and is able to correctly recognize and determine different blood types.
2. Confirm the accuracy of the algorithms and programs: the test is to determine if the algorithms and programs in the design are able to accurately recognize blood types and give correct results.
3. Evaluate the stability and reliability of the instrument: The testing process allows you to observe the stability and responsiveness of the instrument, and evaluate its reliability and performance performance over a long period of time.
4. Detection error and precision: By comparing with known blood types, the error range and precision of the blood type tester can be assessed to understand its credibility and reliability in practical applications.
In short, testing the blood typing tester is to verify its functionality, accuracy and reliability, to ensure that it can accurately recognize the blood type and give the correct results to meet the needs of practical applications.
