Assuming the caliper has no "zero error" (that is, it registers 0.00 mm when fully closed) the vernier caliper definition image shows a reading of 3.58mm ± 0.02mm. This is found by adding 3.00mm (left red mark) read off from the fixed main (upper) scale to 0.58mm (right red mark) obtained from the sliding vernier (lower) scale.

The vernier reading is found by locating the closest aligned lines between the two scales.

Vernier Caliper - Working, Calculation Of Least Count & Zero Error Vernier Caliper - Working, Calculation Of Least Count & Zero Error Posted on September 2, 2015 by Robert Thomson | 3 Comments Vernier Caliper: A device which is used to measure small lengths or distance such as diameter of a cylinder or sphere is called Vernier caliper. With the help of Vernier caliper we can calculate correctly up to 1/1000th of centimeter or 0.1mm Construction: A Vernier caliper consist of a rectangular steel bar whose one side is graduated in centimeters. This scale is also known as “Main Scale (M.S)”. There is also a small scale consisting of ten division which slides over the main scale. This scale is known as Vernier scale (V.S). It has two sets of jaws which enables it to measure the internal and external diameter of the cylindrical objects. Advertisement Working: To measure the length of an abject, it is placed between the two jaws of the Vernier calipers. The distance between the zero of the main scale and the zero of the Vernier scale is equal to length of object. First we find the reading of main scale then find the number of Vernier division which coincide with one of the main scale division. We multiply the vernier divisions by the least count and then ass to main scale reading to get the required length. To get the correct measurement we adjust for the zero error. Least Count Or Vernier Constant: The difference between the value of one main scale division and one vernier division is called as “Least count (L.C) or vernier constant (V.C)” Calculation Of Least Count: Mathematically, the value of least count or vernier constant is calculated as following. 10 vernier division = 9 main scale division =9mm 1 vernier division= 9/10mm 1 vernier division= 0.9mm 1 main scale division= 1mm Least count= 1-0.9 Least count= 0.1mm Least Count= 0.01cm The least count of vernier calipers can also be calculated as following L.C= Value of smaller division on MS/Total Number of division on VS L.C= 1/10 L.C= 0.1mm L.C= 0.01cm ###### Zero Error ##### The error which arises due to the incorrect gradation of the scales of the verneir calipers is called Zero Error. 1. No Zero Error: If the zero of main scale coincide with the zero of the Vernier scale then the instrument has no zero error. 2. Positive Zero Error: If the zero of the venier scale on the right of zero of the main scale then the zero error will be positive, but t
