Term
What is the discrimination of a universal bevel protractor? What scale does it use to reach this degree of accuracy? 

Definition
The universal bevel protractor can read to 5 minutes of a degree. It uses a vernier scale to achieve this accuracy. 


Term
How is a universal bevel protractors vernier scale read? 

Definition
In the same direction you read the main scale (clockwise/counterclockwise) 


Term
How are continuous dial indicators read? 

Definition
In one direction. They are ready when the plunger moves in and out from the dial. 


Term

Term
What is the typical thickness of wear blocks? 

Definition


Term
What are the steps for setting up gauge blocks? 

Definition
Step 1: Use two wear blocks of either 0.1000 each or 0.0500 each. Step 2: Use the first series to eliminate the last digit. Step 3: Use the second series to eliminate the second and third digit if possible, or at the very least make the second digit a 5. Step 4: Use the third series to remove the first and second digit if it is still a 5. Step 5: Use the last series to remove the last digit. Step 6: Add the gauge blocks together and double check your math. 


Term
How do you put gauge blocks together? 

Definition
By wringing them tightly against eachother
