The number of calibration cycles was too few, failing to truly capture the relationship between the deformation and tensile force of the force sensor.
The force sensor itself has a material defect, lacking elasticity, resulting in poor repeatability.
The tensile force used for verification was too large, exceeding the deformation capacity of the force sensor, causing it to malfunction.
The ambient temperature during your calibration differed significantly from the ambient temperature during the experiment. Temperature has a certain impact on the elasticity of the force sensor. It is recommended to add temperature compensation.
