In daily life, we can also use vernier calipers to measure the aperture of the faucet. Check the vernier caliper: whether the zero point is aligned, whether the parts are complete, and whether the sliding is smooth. When measuring the outer diameter, first push the ruler frame larger than the outer diameter of the object to be measured, and then measure.
