How do you calculate the range span of a gage?

• A. Highest point divided by lowest point
• B. Highest point plus lowest point
• C. Highest point minus lowest point
• D. Average of highest and lowest points

Answer: (C)

To calculate the range span of a gage, the correct method is to subtract the lowest point from the highest point. This gives you the total range or span of the measurements that the gage can accurately capture. The rationale behind using subtraction is that the range span represents the difference between the maximum and minimum measurement points. For example, if a gage can measure from a low of 10 units to a high of 50 units, the range span would be calculated as 50 - 10, resulting in a span of 40 units. This calculation is essential for understanding the limits and capabilities of the gage. In contrast to this method, dividing the highest point by the lowest point would not yield a meaningful measure of range, nor would simply adding them together make sense in the context of determining how much the gage can measure. Taking the average of the highest and lowest points also fails to capture the total span or the extent of the gage’s capabilities. Thus, subtracting the lowest point from the highest point is the definitive way to find the range span.
