What term describes the difference between the minimum and maximum readings taken by an indicator?

The term that describes the difference between the minimum and maximum readings taken by an indicator is known as the total indicator reading. This metric is crucial in various maintenance and quality control processes, as it helps assess the variation or deviation of a measurement from a desired specification.

Total indicator reading quantifies how much a particular measurement fluctuates, indicating the precision and accuracy of the alignment or condition of the equipment being assessed. For instance, in machining operations or equipment setup, a lower total indicator reading typically signifies better precision, while a higher reading could indicate misalignment or wear.

Understanding this concept is essential for maintaining equipment in optimal condition, ensuring it operates within acceptable limits, and performing necessary adjustments or repairs to minimize deviations and extend the lifespan of machinery.
