HOW TO READ VERNIER CALLIPER PDF

Close the jaws lightly on the object to be measured. If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord. Ignore the top scale, which is calibrated in inches. Use the bottom scale, which is in metric units.

A Vernier caliper has main jaws that are used for measuring external diameter, as well as smaller jaws that are used for measuring the internal diameter of objects.

Some models also have a depth gauge. The main scale is fixed in place, while the Vernier scale is the name for the sliding scale that opens and closes the jaws. Each scale of your caliper reads like an ordinary ruler.

Typically, a caliper has a main scale marked with numbered inches or centimeters, plus smaller divisions between them. The sliding Vernier scale should have a label engraved on it to tell you what it represents. The main scale is "life size," while the sliding scale is magnified for easy reading.

This magnification system allows the Vernier caliper to measure more precisely than a ruler. Before making a measurement, count the number of lines between two numbers on your Vernier scale. Use this to determine how much distance each of the smallest lines represents. If your Vernier caliper has a locking screw, loosen it before you begin.

Twisting something to the right clockwise will tighten it, while twisting it to the left counter clockwise will loosen it. Before measuring anything, close the jaws and faces to zero out the reading so that you get a precise measurement. Subtract 1 mm from all measurements to get the right result. If the zero on the sliding scale is to the left of the main scale zero, you have a negative zero error. Slide it so the zeros line up, while watching another mark to see the size of the error.

For example, if the 0. Add 1. You should not use 0. Guess again! The smallest line in this example is 0. Read on for another quiz question. It depends on different factors. Not quite! Pick another answer! Want more quizzes?

Main article: Vernier acuity Vernier scales work so well because most people are especially good at detecting which of the lines is aligned and misaligned, and that ability gets better with practice, in fact far exceeding the optical capability of the eye. This ability to detect alignment is called Vernier acuity. In case of vernier calipers it occurs when a zero on main scale does not coincide with a zero on vernier scale. The zero error may be of two types: when the scale is towards numbers greater than zero it is positive; else negative. Zero error may arise due to knocks that cause the calibration to be thrown off at the 0. Perfection is not necessarily equal to scalar to zero error.
