What is a dial indicator used for in a maintenance shop?

• A. Measuring small displacements, runout, and alignment with high accuracy.
• B. Measuring temperature.
• C. Checking paint thickness.
• D. Testing electrical continuity.

Answer: (A)

Dial indicators are precision tools that measure tiny linear movements and translate them into a readable dial. In a maintenance shop they’re used to detect small displacements, check runout on rotating parts, and verify alignment between surfaces. Because they can sense very small changes in position with high accuracy, they’re ideal for ensuring parts run true and are correctly aligned to spec. Temperature, paint thickness, and electrical continuity require different instruments, so they don’t fit the purpose of measuring precise positional changes.
