Dial Caliper Measurement Techniques

This video tutorial explains how to use a dial caliper for precise measurements. It covers reading the scale and dial, setting up the caliper by closing the jaws and setting the dial to zero, and adjusting the caliper to measure dimensions. The tutorial also details how to read the steel scale and dial increments, and how to calculate the total measurement value by adding the readings from both the scale and the dial.

What is the first step in using a dial caliper?

• Adjusting the jaws to fit the object

• Reading the dial scale

• Understanding the scale and dial

• Locking the dial lock screw

What should you do after closing the jaws of the caliper?

• Set the dial to zero

• Read the steel scale

• Adjust the caliper to fit the object

• Lock the top screw

How do you ensure the caliper is ready for measurement?

• By setting the dial to zero

• By adjusting the jaws

• By locking the dial lock screw

• By reading the dial scale

What is the purpose of the adjustment screw on a dial caliper?

• To close the jaws together

• To set the dial to zero

• To read the dial scale

• To lock the top screw

When is the top screw of the caliper locked?

• After reading the dial scale

• After making contact with the object

• After setting the dial to zero

• After reading the steel scale

What should be done if the caliper does not fit the object?

• Set the dial to zero

• Lock the top screw

• Adjust the jaws

• Read the dial scale

What is the distance between each major increment on the steel scale?

• One thousandth of an inch

• One hundred thousandths of an inch

• One inch

• Four thousandths of an inch

How is the measurement taken on the steel scale?

• By setting the dial to zero

• By aligning the needle with the increment

• By closing the jaws

• By reading the distance between major increments

What is the significance of the inside edge of the right jaw?

• It sets the dial to zero

• It locks the top screw

• It aligns with the steel scale

• It aligns with the dial scale

What is the distance between each increment on the dial?

• One thousandth of an inch

• Four thousandths of an inch

• One hundred thousandths of an inch

• One inch
