Question

How do you read a zero vernier caliper?

Answer 1

Answer:

Zero error is the reading measuring device when the input quantity is zero.

Explanation:

Zero error is defined as condition where measuringan  instrument records  reading when not at all reading is required. In case of the Vernier calipers  occurs when the  zero on main scale doesn’t  coincide with zero on Vernier scale it is called zero error for Vernier.

Answer 2

The read of a zero vernier calliper is:

• The vernier scale, coined by Pierre Vernier, is a useful tool for taking accurate readings between the two graduation marks on the line scale using machine translation, thereby increasing resolution and minimizing measurement uncertainty using vernier acuity to reduce human error measurement.
• It is used to calculate the internal and external diameters of empty cylinders.

How to use a vernier scale or a zero calliper error using the formula:

• Read the scales on your Vernier scale.
• Reading in 3.
• Therefore reading 3.
• Lock the slide with a screw if necessary.
• A serious zero error is when the zero mark of the vernier scale lies on the left side of the zero marking mark of the larger scale.
• A good zero error is when the zero marker of the vernier scale lies to the right of marking the zero scale.
• No zero error means a completely aligned line.
