What term is used to describe the maximum possible reading of a pressure gauge?

• A. Scale
• B. Range
• C. Graduation
• D. Accuracy

Answer: (B)

The maximum reading is determined by the range of the gauge. A pressure gauge can display values from a minimum up to a maximum, and the upper limit of that span is what we call the range. The scale is just the series of marks along the dial, and graduations are the individual marks you read between those marks. Accuracy, on the other hand, describes how close the indicated value is to the true pressure, not the maximum the instrument can show. So the term that describes the largest possible reading is the range.
