Vernier caliper is a tool used for precisely measuring the length, inner diameter, outer diameter, and depth of objects. Its main function is to provide high-precision dimensional measurements, commonly used in engineering, manufacturing, and scientific experiments. Below is a detailed description of the functions, instructions for use, and precautions of vernier calipers.
Firstly, the vernier caliper consists of a main scale, vernier scale, locating jaws, and measuring jaws. The main scale is usually located at the bottom of the vernier caliper and is used to measure the primary length of the object. The vernier scale is a movable scale fixed on the main scale, providing more accurate measurement results. The locating jaws and measuring jaws are located at the end of the vernier caliper and are used to measure the inner diameter, outer diameter, and depth of objects.
When using the vernier caliper, ensure that the measuring jaws are clean and gently place them on the object to be measured. Then, by rotating the locating jaws or moving the vernier scale, bring the measuring jaws into contact with the object and snugly fit them. Next, read the scales on the vernier and main scales, typically aligning the vernier scale with the closest mark on the main scale and adding the vernier scale reading to the main scale reading to obtain the final measurement result.
When using the vernier caliper, attention should be paid to the following points:
1. Handle with care: Handle the vernier caliper with care, gently moving the vernier and locating jaws to avoid damaging the object or the tool.
2. Accurate reading: Due to the high precision provided by the vernier caliper, ensure that the vernier and main scales are accurately aligned when reading the scales to avoid measurement errors.
3. Keep clean: Regularly clean the measuring jaws and scales of the vernier caliper to ensure accurate measurement results.
4. Avoid excessive force: When taking measurements, do not apply excessive force to prevent damaging the vernier caliper or the object being measured.
5. Proper storage: When not in use, store the vernier caliper in a dry, clean environment to prevent moisture damage or damage from external objects.
