Understanding Measuring Tools

How do you read a dial gauge accurately?

• Read the dial from above for a better view.

• Read the dial at eye level, note the needle position, and estimate between scale divisions if necessary.

• Only look at the dial when the machine is off.

• Ignore the needle and focus on the dial's color.

What is the difference between a steel tape and a ruler?

• A steel tape is flexible and used for longer distances, while a ruler is rigid and used for shorter measurements.

• A steel tape is used for measuring angles, while a ruler is used for measuring distances.

• A steel tape is always longer than a ruler, regardless of the type.

• A steel tape is made of plastic, while a ruler is made of metal.

Describe the use of an L-square in measurements.

• An L-square is used to ensure accurate right angles in measurements and alignments.

• An L-square is a tool for cutting materials at an angle.

• An L-square is primarily used for measuring distances.

• An L-square is used to measure the circumference of circles.

What are dividers used for in precision measuring?

• Dividers are used for measuring weight accurately.

• Dividers are used for cutting materials precisely.

• Dividers are used for transferring measurements and marking distances accurately.

• Dividers are used for creating electrical circuits.

Explain how a level bar ensures accuracy in leveling.

• A level bar measures the weight of the object being leveled.

• A level bar uses a laser to project a straight line for alignment.

• A level bar is designed to withstand extreme temperatures for durability.

• A level bar ensures accuracy by providing a visual reference for true horizontal alignment, indicated by a centered bubble in the vial.

What is the purpose of a depth gauge?

• To determine the color of materials.

• To measure temperature variations.

• To calculate weight accurately.

• To measure depth or thickness accurately.

How do you use a feeler gauge to measure gaps?

• Use a digital caliper to measure the gap directly.

• Select the correct thickness gauge blade, insert it into the gap, and adjust until you find a snug fit.

• Estimate the gap size by eye without any tools.

• Measure the gap with a ruler and record the length.

What does a screw pitch gauge measure?

• The weight of a screw.

• The color of a screw.

• The material composition of a screw.

• The distance between threads on a screw (screw pitch).

How do you read measurements on a vernier caliper?

• Estimate the measurement by eye without using the scales.

• Use the sliding scale measurement alone for accuracy.

• Read the main scale and add the aligned fractional part from the sliding scale.

• Read only the main scale without the sliding scale.

What is the maximum measurement range of a typical micrometer caliper?

• 0 to 50 mm

• 0 to 100 mm

• 0 to 150 mm

• 0 to 200 mm
