A caliper is a part used To gauge short distances between two sides of a symmetrically shaped intent. Dial calipers consist of a two metal tips, one of which slides along a track that is connected to Hand-bill dial that turns as tips predispose farther apart. Calipers can be used To gauge objects such as nuts, bolts, Spike heads and other rounded objects correct accurately.
Instructions
1. Disinfected the measuring surfaces of the calipers and the surface of the protest to be measured. Both surfaces should be unpaid of obstructive debris to receive the most accurate measurement likely.
2. Fast the calipers so both measuring orifice are flush stable, and beget undeniable the dial reads insignificancy. Whether the dial does not glance at love when the measuring entrance are stable, your reading Testament be inaccurate.
3. Open the jaws of the caliper and place them around the object you wish To gauge.
4. Close the jaws around the object, so that each jaw makes a right angle with body of the caliper and there is no space between the jaws and the object.
5. The dial measures very small distances that would be more difficult to discern with the naked eye on the ruler scale. The ruler portion measures in larger units such as centimeters and millimeters, while the dial measures in fractions of a millimeter, so adding them up may just be a matter of adding decimal places onto the ruler scale measurement.
Read the measurement on the ruler scale first. There will be a measurement on the caliper above the object, to the left of the dial that looks like a normal metal ruler.6. Add the measurement on the ruler scale, to the reading on the dial.
