• Handle

What is the purpose of the dial or digital display on a dial caliper?

• To play music

• To provide weather updates

• To provide an accurate measurement reading

• To make coffee

How do you read the measurement on the main scale of a dial caliper?

• By shaking the caliper and guessing the measurement

• By looking at the number indicated by the edge of the main scale that lines up with the reference line on the dial.

• By counting the number of lines on the main scale

• By using a magnifying glass to read the tiny numbers

Explain how to read the measurement on the dial or digital display of a dial caliper.

• Subtract the measurement on the dial from 100 to get the correct reading

• Place the object between the jaws and read the measurement where the edge of the object aligns with the scale on the dial or digital display.

• Add the measurement on the dial to the length of the caliper to get the total measurement

• Count the number of lines on the dial and divide by 10 to get the measurement

When using a dial caliper to measure the thickness of an object, what is the correct procedure to follow?

• Ensure the jaws are clean, gently close around the object, and read the measurement from the dial.

• Guess the measurement without closing the jaws

• Use a dirty caliper to measure the thickness

• Slam the jaws shut around the object

How do you use a dial caliper to measure the depth of a hole?

• Use a ruler to measure the depth

• Place the depth rod into the hole and read the measurement on the dial scale.

• Count the number of rotations of the dial scale

• Estimate the depth by eye

Explain the steps to measure the outside diameter of a cylindrical object using a dial caliper.

• Carefully place the object between the jaws of the caliper, ensuring it is perpendicular to the measuring faces. Gently close the jaws until they make contact with the object, then read the measurement on the dial scale.

• Slam the object into the caliper as hard as possible

• Use a ruler instead of a dial caliper to measure the diameter

• Guess the measurement without actually using the caliper
