While the vernier scale reading is the amount of vernier scale divisions from 0 to the aligned line. You could see the following picture. The first left yellowed line shows how many divisions passed by the vernier 0 marking.
In this case, it has passed 42 divisions. While the second right yellowed line shows the aligned line. Therefore, the main scale reading depends on the vernier scale, while the vernier scale reading depends on the aligned line. What is the aligned line? Whenever you slide the vernier scale, there must be two lines one from the main scale and one from the vernier scale that completely shape a united straight line.
The vernier scale functions to divide the smallest division of the main scale into a particular amount of divisions so that it generates the desired resolution. If the main scale has 40 divisions per inch, it means each smallest division on the main scale has a value of 0. To generate a 0.
Prior to reading the vernier caliper, you need to check whether the zero error exists or not. Keep measuring without taking the zero error into calculation, you are measuring in an incorrect way. It happens when you close both the two jaws fixed and movable jaw properly. There are 3 possibilities that may happen: no zero error, negative zero error, and positive zero error. If you find a misalignment either positive or negative zero error , you have to include it in the calculation of the final measurement.
Basically, to read the zero error is the same as to read the vernier caliper as usual. It takes both the main and vernier scales to measure. However, it can be confusing when you are facing a negative zero error. Fortunately, by creating an imaginary additional scale like the following image, you can start putting the measurement in a fixed formula. The first step that you have to do is to define the value of each smallest division for both the main and vernier scale.
Decide whether the scale is imperial inches or metric mm. In this case, the above scale is inches. By looking at the graduation, we know that the main scale has 20 divisions per inch and the vernier scale has 50 divisions. The second step is to count the main and the vernier scale, then add them altogether. Actually, there is a shorter way of reading the zero error.
But we just want to make sure that you know this basic measurement before jumping into the shortcut method. The shorter way is by reading in reverse. If you find the vernier scale graduated from left to right. You can imagine that the increment 0 to 50 is graduated from right to left.
Just directly measure zero error from the 0 markings of the vernier scale, and you will get the answer. But, this method works only when the zero error is less than the smallest main scale division value.
When it comes to metric vernier caliper, there are several resolutions available: 0. Different resolution has different graduation model.
Soon, you will know the graduation models that we mean and how to read them. We name them as model 1 0. Among these models, model 1 is the most used and easily found on the market. This model has 10 divisions per cm on its main scale and 50 divisions on its vernier scale.
Example of vernier caliper that comes with this graduation model is Mitutoyo vernier caliper. This model has 10 divisions per cm on its main scale and 20 divisions on its vernier scale.
