# *Precision Measuring Instruments (Complete Course)

56,000.00

The lessons in Precision Measuring Instruments were designed for employees in all disciplines as well as for the multi-craft training needs of process and manufacturing facilities. In order to successfully complete these lessons participants should be familiar with whole number operations and decimals. This course describes the purpose and the basic components of some common precision measuring instruments. The course also provides procedures for properly using each of these instruments to measure the dimensions of an object.

## Course Objectives

• Identify the beam, dial, and nibs of a dial caliper.
• Explain how to read a dial caliper and zero a dial caliper.
• Explain the use of the two sets of nibs on a dial caliper.
• Obtain the inside measurement of an object by using a dial caliper.
• Obtain the outside measurement of an object by using a dial caliper.
• Identify the main components of an outside, inside, and depth micrometer.
• Explain how to read a micrometer.
• Measure outside dimension using an outside micrometer.
• Measure inside dimension using an inside micrometer.
• Measure depth by using a depth micrometer.
• Measure the inside diameter of an object by using a telescoping gauge in conjunction with an outside micrometer.
• Demonstrate the proper way to insert and remove a telescoping gauge.
• Measure a clearance with a thickness gauge.
• Explain how to double-check your measurements.
• List some of the common uses of a dial indicator and explain how a dial indicator works.
• Explain how to determine if a reading is positive or negative.
• Describe the procedure for determining if a dial indicator is positioned properly.
• Describe how to determine if the dial indicator is secure.
• Measure small changes in dimension by using a dial indicator.
