What is the 'zero error' in vernier calipers and micrometer screw gauge?

In vernier calipers, zero error is when the jaws of the caliper do not close properly when they are in contact without measuring anything, resulting in a measurement that is not accurate. In a micrometer screw gauge, zero error occurs when the flat end of the spindle does not perfectly align with the reference line on the sleeve at zero reading, leading to inaccurate measurements.


Why is it necessary to measure the expansion with a micrometer screw gauge?

A micrometer screw gauge is necessary for measuring expansion because it provides precise and accurate measurements to determine the small changes in length that occur due to expansion. The micrometer screw gauge has a fine scale and a thimble that allows for consistent and repeatable measurements, making it suitable for measuring small increments of expansion.


What is the micrometer screw gauge used for?

A micrometer screw gauge is used to measure small dimensions with high precision. It consists of a screw mechanism that moves a calibrated scale when measuring the dimensions of objects. It is commonly used in fields such as engineering, manufacturing, and science where accuracy is important.


Can 47mm be azero error in screw gauge?

No, a zero error in a screw gauge indicates that the initial reading is not starting from zero. So, 47mm cannot be a zero error unless the screw gauge is not calibrated correctly.


What is the function of anvil on micrometer screw gauge?

The anvil on a micrometer screw gauge is used to support and hold one end of the object being measured. It helps to ensure that the object is positioned correctly for accurate measurements to be taken by the gauge.

What is the precautions you should take when using a micrometer screw gauge?

it should be clean and dry there should be no error the thimble shouldnt be too tight


What is the function of sleeve in micrometer screw gauge?

The sleeve in a micrometer screw gauge helps to accurately measure small distances by providing a scale with markings that align with the spindle scale for precise readings. This allows for measurements to be taken with high precision and accuracy.
