(Summary description)1. Observe the range, that is, the measurement range. As shown in Figure 1, the range of the spring dynamometer is 5N. The measured force must be estimated before use. The measured force cannot exceed the range of the spring dynamometer, otherwise it will be damaged Spring dynamometer. 2. Observe the division value of the spring dynamometer, that is, the value represented between the smallest two scales, and understand the size of the division value, which is conducive to correct reading. As shown in Figure 1, the division value of the spring dynamometer is 0.2N. 3. Observe whether the pointer is pointing to the zero scale line. If it is not, adjust to zero, otherwise the measurement result will be inaccurate. As shown in Figure 2(d), the pointer is below the zero scale value when no force is applied, and the section above the pointer when reading after measurement The value is read in, causing the measurement result to be too large. 4. Before using the spring dynamometer, you should gently pull the hook back and forth several times, the purpose is to see if the spring is in contact with the shell, rubs, and is not flexible.
