Simple spring checker

Our factory has produced 500,000 outlets of 1kg medical spring scales. The scale of the scale on the outer tube is 60mm, which is divided into 50 divisions and the division distance is 1.2mm. The calibration time is determined by measuring 0.500g and 1kg of three points, and the tolerance is ±1/4 division. That is, the deformation of the spring is 60±0.30mm under the gravity of 1kg, and the deviation of the force deformation is ±0.5%.
