Scope
Main technical content: 4. Measuring characteristics: - Hammer weight: 500g, with an allowable deviation of ±1g. - Base diameter: 50mm, with an allowable deviation of ±1mm. - Steel ball diameter: 12.7mm, with an allowable deviation of ±0.1mm. 6. Calibration methods: 6.1 Hammer weight: Use a balance to measure the hammer weight three times, and take the average value as the calibration result. All three measurement values should meet the technical requirements of the equipment. 6.2 Base diameter: Use a vernier caliper to measure the diameter in two perpendicular directions of the base. Take the average value of the two measurement values in the same cross-section of the base as the calibration result. Both measurement values in the two directions should meet the technical requirements of the equipment. 6.3 Steel ball diameter: Use a micrometer to measure the steel ball diameter. Take the average value of the four measurement values at any four positions of the steel ball as the calibration result. All four measurement values should meet the technical requirements of the equipment.
