Venier Caliper

1: Make sure that the vernier Calliper is properly zeroed. To do this, loosen the locking screw and adjust the movable jaw until the zero mark on the vernier scale aligns with the zero mark on the main scale.

2: Place the object to be measured between the fixed and movable jaws.

3: Tighten the locking screw to secure the movable jaw in place.

4: Read the measurement from the main scale and the vernier scale. The main scale will give you the overall length of the object, while the vernier scale will give you the small increments of length.

To ensure accurate measurements, begin by verifying the alignment of the main and vernier scales with nothing in between. When both scales read zero, zero error is eliminated. Introduce a ball between the vernier scale jaws, aligning the 0 mark on the vernier scale with the main scale to obtain the main scale reading. Identify the point on the vernier scale aligned with the main scale for the vernier scale reading. Note that readings often involve decimals, with the number before the decimal indicating the main scale reading and the number after the decimal representing the vernier scale reading.
