1. Reporting rate: too fast, the CPU can not respond in time, which may cause drops, and the line is easy to break

2. Accuracy: 99% accuracy

3. Sensitivity: less than two ounces of force can be sensitized, less than 3ms fast response

4. Resolution: It is related to the number of channels in the X and Y axes, the more channels, the higher the resolution. The higher the resolution, the higher the contact accuracy

5. Reporting range: This is generally the same as the resolution setting of LCD.

6. Linearity: Linearity defines the degree of closeness to which the practical output of the equipment is consistent with the ideal straight line in the entire operating range.

7. Anti-interference ability: high temperature; Electromagnetic field; oil, water; Electrostatics.

8. Hardness, compressive resistance: completely scratch-resistant glass material (Mohs hardness 7H), not easy to be scratched and worn by sharp objects.

9. Power consumption:

10. Clarity: If the glass material is not good, it will affect the clarity.

11. Reporting rate: the number of times contact information is reported to the host per second.
