The strip in a vernier caliper serves as a reference scale for taking precise measurements. It allows users to align the main scale and the sliding vernier scale accurately, facilitating the reading of measurements with enhanced precision. By combining the readings from both scales, users can determine the exact dimensions of an object with a high degree of accuracy.
The two types of measurements taken with a vernier caliper are internal measurements and external measurements. Internal measurements are used to measure the diameter or width of an object, while external measurements are for measuring the length or thickness. Additionally, a vernier caliper can also measure the depth of an object using its depth rod. This versatility makes it a valuable tool in various fields such as engineering and woodworking.
To enhance the accuracy of a vernier caliper, ensure that it is properly calibrated before use, checking for any zero error by aligning the main scale and the sliding vernier scale to see if they read zero when closed. Regularly clean the measuring surfaces to prevent any debris from affecting measurements. Additionally, use consistent measuring pressure and technique, and take multiple measurements for an average to minimize random errors.

The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
The gradations are in micrometres.
It can, but the vernier is capable of a more accurate reading.

well it depends on what actual type it is, for there is many versions of the vernier and it can be inchs feet and centimeters

look for the zero marking in the main scale and focus your eyes to the mark below it.
