Software Function Requirements:
1. Features parameter recommendation function, suggesting suitable probes and parameters based on set inspection object information
2. Features instrument sensitivity adjustment function, allowing calibration using standard test blocks
Features defect depth coefficient calibration function, allowing depth coefficient setting using reference test blocks
3. Features excitation adjustment function, allowing adjustment of inspection frequency and excitation level based on the inspection object, with automatic adjustment of instrument gain
4. Inspection interface vertical axis supports switching between follow mode and fixed mode, adjustable at any time
5. Features inspection image zoom function, allowing manual zoom and horizontal dragging for result viewing
6. Features image reset function, allowing one-click restoration of zoomed or dragged images
7. Supports inspection image replay function for multiple reviews
8. Features marking function. Clicking the mark button during inspection adds dividers to the inspection image for segmented display in reports
9. Supports defect sizing function. After identifying a defect, selecting its area allows calculating defect length based on encoder data. Surface opening defect depth can be calculated based on Bx signal variation
10. Supports custom inspection report formats and report export function
11. Supports viewing inspection reports, images, and data from historical project files
