What is the procedure for measuring the diameter of an object using Vernier calipers?
Understand the Problem
The image provided describes how to use Vernier calipers to measure the diameter of an object, specifically by closing the jaws until they gently press on both sides of the object.
Answer
Read main and Vernier scales, then add measurements.
Use the main jaws to hold the object gently. Read the main scale: the reading just before the Vernier scale's zero. Check the Vernier scale for the line that aligns with the main scale. Add these readings for the diameter.
Answer for screen readers
Use the main jaws to hold the object gently. Read the main scale: the reading just before the Vernier scale's zero. Check the Vernier scale for the line that aligns with the main scale. Add these readings for the diameter.
More Information
Vernier calipers provide a direct reading between scales for precise measurements, often to the nearest 0.01 mm.
Tips
Ensure the caliper is zeroed before measuring to avoid errors.
