To find the highest and lowest points of a gage, one must:

• A. Subtract the lowest from the highest
• B. Add the highest and lowest together
• C. Divide the highest by the lowest
• D. Multiply the highest by the lowest

Answer: (A)

To determine the highest and lowest points of a gage, one effective method is to subtract the lowest value from the highest value. This approach provides a clear measure of the range or span of the measurements, indicating the difference between the peak and the lowest point. The result gives a direct indication of how much the values fluctuate, which is essential in calibration processes where understanding the limits of a measurement tool is critical. By calculating the difference, technicians can ascertain how effectively the gage is performing across its range, and whether it falls within specified tolerances. This practice aligns directly with standard calibration procedures where measurements are often assessed in terms of their maximum and minimum values to ensure accuracy and reliability in measurements. Other methods of calculation, such as addition, division, or multiplication, do not provide meaningful insights into the variation of the gage's measurements, as they either compound values or create ratios that do not relate directly to the measurement range being studied. Thus, finding the highest and lowest points of a gage through subtraction is the most practical and informative approach.
