Enter the "System Settings" interface to set the inspector, test unit, and other parameters, and then enter the "Start Detection" interface to prepare for detection.

4. Spectral Collection: Place the sample bin with the samples into the instrument. Click the "Detection" button, enter the sample number as prompted, and the instrument starts to collect the near-infrared spectrum of the sample. The collection process is automatically completed by the instrument, and the user only needs to wait for the collection to finish.

5. Result Calculation and Display: After the spectral collection is completed, the instrument uses the built-in PLSR model to analyze and calculate the spectral data, and obtains the contents of protein, fat, water-soluble protein, moisture, and fiber in the soybeans. The calculation results are directly displayed on the instrument's display screen, and the user can clearly view the specific value of each indicator.

6. Result Verification and Confirmation: To ensure the reliability of the detection results, it is recommended to repeat the detection of the same sample 3-5 times. After obtaining multiple sets of detection results, calculate the average value. If the difference between each set of results is small (within the allowable error range), the average value is taken as the final detection result of the sample; if the difference is large, check whether the sample loading is uniform, whether the instrument is stable, and other factors, and re-detect.

7. Result Recording and Output: Record the final detection result manually or by clicking the "Save" button on the instrument to store the result in the instrument's local memory. If a paper report is needed, click the "Print" button to print the detection report through the built-in thermal printer. The report can be used for data archiving, quality evaluation, or providing data support for subsequent work such as trading and production.

8. Post-Detection Cleaning: After the sample detection is completed, take out the sample bin from the instrument, pour out the detected soybeans, and use the sample bin brush to clean the sample bin thoroughly to remove residual soybean particles and prevent cross-contamination between subsequent samples. At the same time, wipe the surface of the instrument with a clean cloth to keep the instrument clean.
