How is the tolerance of a gage determined?

• A. By multiplying range span by accuracy
• B. By subtracting the lowest point from the highest point
• C. By adding range span to the accuracy
• D. By multiplying accuracy by range span

Answer: (A)

The method of determining the tolerance of a gage emphasizes understanding both the accuracy of the instrument and its range of measurement. When you calculate the tolerance, it is often derived from the interaction between the accuracy and the range span. Specifically, the tolerance is established by multiplying the range span — which is the difference between the upper and lower limits of measurable values — by the accuracy of the gage. This relationship is crucial because it reflects how much deviation is acceptable within the context of accurate measurements. For instance, if a gage has a specified accuracy of 1% and it measures a range from 0 to 100 units, the range span is 100. Multiplying 100 by 0.01 (1%) results in a tolerance level that helps define the acceptable limits for reliable readings. In contrast, the other options do not accurately capture the standard method of determining tolerance in a way that considers both accuracy and range span. Understanding this calculation method enables calibration technicians to establish proper guidelines and thresholds for the performance of measuring instruments, ensuring accurate and reliable readings in various applications.
