Question: 1 / 400

The continuous-reading dial indicator starts at zero and increases in which direction?

Counterclockwise

Clockwise

A continuous-reading dial indicator is designed to provide a clear reading of measurements, and it typically has a needle or pointer that moves along a scale. In most designs, this pointer moves in a clockwise direction as the measurement increases from a zero point. This functionality allows for easier interpretation of the reading, as a clockwise movement is standard for many measuring instruments, aligning with general expectations in mechanical measurement systems.

Understanding the directionality is crucial when using the dial indicator for precise measurements, as it helps the user to quickly assess the readings without confusion. The consistent use of clockwise movement across various tools helps standardize measurement practices in mechanical and millwright contexts.
