A Vernier caliper is quite accurate and idiot proof. Part of its accuracy lies in its general ease of use.
The zero error for a Vernier caliper is the systematic error that occurs when the jaws do not exactly close at zero. The reading uncertainty for a Vernier caliper typically depends on the precision of the scale divisions, with the main scale usually indicating whole millimeters and the Vernier scale providing readings to the nearest 0.02 mm.
The vernier caliper is used to measure linear dimensions, such as length, width, and thickness, with high precision. It can measure the distance between two opposite sides of an object by using a sliding scale and a vernier scale for more accurate readings.

The principle of a vernier caliper is that it uses a main scale and a sliding vernier scale to provide accurate measurements of length, thickness, or diameter. The vernier scale has a slightly smaller increment than the main scale, allowing for precise readings to be taken. By aligning the zero mark on the vernier scale with the closest mark on the main scale, the user can determine the measurement with high accuracy.
The vernier caliper was invented in 1631 by Pierre Vernier, a French mathematician and scientist. It is a precise measuring instrument that allows for accurate readings of length measurements.

A screw clamp on a vernier caliper is used to secure the position of the jaws once a measurement has been taken. By tightening the screw clamp, the jaws are held in place to prevent accidental movement and ensure accurate readings. This feature helps to maintain the precision and consistency of measurements taken with the caliper.
A Vernier detects small differences in measurements with precision. It is widely used in scientific instruments such as calipers and micrometers to provide accurate readings for various applications like engineering, physics, and chemistry.

The zero reading of a vernier caliper is when the jaws are closed and the main scale '0' mark aligns perfectly with the zero mark on the vernier scale. This is the reference point for taking measurements with the vernier caliper.
To measure the inside diameter of a ring using a vernier caliper, you can gently open the jaws of the caliper, place them inside the ring, and then slowly close the jaws until they fit snugly against the inner circumference of the ring. Take the reading from the main scale and vernier scale where they align. This will give you the inside diameter measurement of the ring.
The vernier caliper jaws close gently to prevent damaging the object being measured and to ensure accurate readings. Applying excessive force can distort the measurement and affect the precision of the caliper's reading. Gently closing the jaws also helps in maintaining the longevity and accuracy of the caliper.
