Experiment # 1: Measurement

2. Measurement Process
The determination or estimation of magnitudes of quantities.
The process of obtaining the magnitude of a quantity, such as length or mass, relative to a unit of measurement, such as a meter or a kilogram.

3. Objective
To learn the basic skills of measuring an object using some standard tools and methods.

4. Experiment Tools
Vernier Caliper
Micrometer

5. Caliper
It is an instrument used to measure linear dimensions ( length, depth,..).

6. Types of Calipers
Outside Caliper
Inside Caliper

7. Divider Caliper
Oddleg Caliper

8. Vernier Caliper

9. Dial Caliper

10. Digital Caliper

11. Vernier Caliper It can measure: Internal dimensions,
External dimensions, and
Depth by the use of a probe.

12. How does it work?

13. Instructions on Use
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.
The boldface numbers on the fixed scale are centimeters.

14. Micrometer It is more accurate than the Vernier caliper.
It allows the measurer to have up to accuracy.
