1. Applied Math I English and Metric Calipers

2. Overview In this lesson you will learn about: The different kinds of calipers. The components of a typical caliper. Caliper usage. Reading English and metric measurements from calipers.

3. Introduction Calipers are tools used in home, small shop, and industrial settings. They are used to make precise length measurements.

4. Introduction Some reasons for their popularity include: Wide measuring range (usually 0 - 6”). English and metric scales are usually found on the same instrument. Many different kinds of measurements can be made with a caliper...

5. Introduction While both micrometers and calipers can make outside length measurements...

6. Introduction Calipers can also make inside measurements...

8. Introduction There are three types of calipers. The vernier caliper:

9. Introduction The dial caliper:

10. Introduction …and the digital electronic caliper.

11. Introduction In this lesson, we will concentrate on the vernier caliper since it takes the most skill to read.

12. Introduction These are the main features of a typical vernier caliper:

13. Reading a Caliper: English To determine the length of an object in inches, you must be able to read the English scale on the caliper.

14. Reading a Caliper: English Most of the measurement information is going to come from the fixed English scale. Just think of it as a ruler.

17. Reading a Caliper: English Reading a caliper is a process of collecting measurements from the fixed scale and the vernier scale. To stay organized, write down each measurement in a column, being careful to keep the decimal points lined up.

19. Reading a Caliper: English The largest fixed scale divisions are the one-inch intervals, so start there first.

26. Reading a Caliper: English Let’s review the procedure once again...

34. Let’s obtain a reading from this caliper:

58. Reading a caliper: metric Start by obtaining a measurement from the fixed scale...

68. Reading a caliper: metric Let’s try another one for practice.
