Step 1:: Understand the question and list possible uses of a dial indicator.
A dial indicator is a precision measuring instrument used to measure small linear movements, typically in the range of 0 - 0.025 inches (0 - 0.635 mm). It consists of a plunger that moves in and out as it comes in contact with the object being measured. The plunger's movement is amplified and displayed on a dial gauge.
Step 2:: Identify the common uses of a dial indicator.
- Measuring the runout of a part - Checking the diameter of a part
Step 3:: Exclude less common uses of a dial indicator.
- Measuring spark plug gap: This is typically measured with a feeler gauge, not a dial indicator. - Measuring angles on parts: Dial indicators are not designed to measure angles. Instead, engineers use protractors, sine bars, or other angle-measuring tools.
Final Answer
A technician would use a dial indicator to measure the runout of a part or check the diameter of a part.
