## Practice On Reading A Vernier Caliper _ Mini Physics - Learn Physics Online.pdf

### Virtual Vernier Caliper - simulator in Millimeter Prof. Eduardo J. Stefanelli

The reading is therefore 3. The reading is 3. We will see how this is done taking with the help of examples. BobWelds says: How does the scale of a metric vernier caliper work? Duplicate Quiz Cancel. The value on the main scale is the number immediately to the left of the 0 marker of the vernier scale. The smallest value that can read from the main scale is 0.

The first significant figure is taken from the last graduation showing on the sleeve directly to the left of the revolving thimble. Answers Figure 7: I love your simple approach so much. An abridged version. Thus, the final reading of the vernier is As the zero is half way between 0. For any movement, only one pair of marks aligns and that pair shows the value between the marks on the fixed scale.

Hariharan Ramakrishnan says: Figure 5: Zero error is defined as the condition where a measuring instrument registers a reading when there should not be any reading. The micrometer screw gauge also uses an auxiliary scale measuring hundredths of a millimetre which is marked on a rotary thimble. The remaining two digits are taken from the vernier scale reading that lines up with any main scale reading, i. What Others Are Saying: In the cursor is recorded a second scale called vernier scale or nonius.

Reply to afra ayaz. Let the measure of the smallest main scale reading, that is the distance between two consecutive graduations also called its pitch be S and the distance between two consecutive Vernier scale graduations be V such that the length of n-1 main scale divisions is equal to n Vernier scale divisions. The Vernier principle of interpolation is also used for electronic displacement sensors such as absolute encoders to measure linear or rotational movement, as part of an electronic measuring system.

Again observing the figure carefully, it is observed that the 60 th division exactly coincides with one of the divisions on the main scale. Figure The vernier is a subsidiary scale replacing a single measured-value pointer, and has for instance ten divisions equal in distance to nine divisions on the main scale.

Both the main scale and the vernier scale readings are taken into account while making a measurement. The diagram shows part of a micrometer screw gauge.
