Background
The vernier caliper is a measuring instrument commonly used in industry, and is a measuring tool for measuring length, inner diameter, outer diameter and depth. The main scale and the vernier of the vernier caliper are provided with two pairs of movable measuring claws, namely an inner measuring claw and an outer measuring claw, wherein the inner measuring claw is generally used for measuring the inner diameter, and the outer measuring claw is generally used for measuring the length and the outer diameter.
When reading, firstly, the whole millimeter number, namely the whole number part in millimeter unit, is read on the ruler body based on the vernier zero scale mark. And then, a few scale marks on the vernier are aligned with the scale marks of the ruler body, if the 6 th scale mark is aligned with the scale marks of the ruler body, the decimal part is 0.6 mm (if no line is aligned exactly, the line closest to the alignment is taken for reading). If there is zero error, then the result is uniformly subtracted by zero error (zero error is negative, which is equivalent to adding zero error of the same magnitude), and the reading result is: and L is an integer part + a decimal part-zero error, which scale mark on the vernier is aligned with the scale mark of the ruler body can be judged by the following method: three adjacent lines are selected, for example, the left line is right of the corresponding line of the ruler body, the right line is left of the corresponding line of the ruler body, the middle line can be regarded as aligned L (aligned front scale mark + aligned nth scale mark on the vernier with the scale mark of the ruler body) x (multiplied by) division value, if measurement is needed for several times, averaging is not needed, zero error does not need to be subtracted every time, and only the zero error needs to be subtracted from the final result.
