In what increments should a gauge measuring a magnitude of 5 psig be calibrated at a minimum?

• A. 1/4 inch
• B. 1/5 inch
• C. 1/10 inch
• D. 1/2 inch

Answer: (B)

To determine the minimum increments for calibrating a gauge measuring a magnitude of 5 psig, it is essential to consider the practical requirements for measurement accuracy and sensitivity in high-pressure systems. In this case, a gauge designed to measure pressures up to 5 psig should provide readings that allow for accurate and responsive monitoring of pressure changes. The calibration increment chosen must facilitate a clear understanding of minor fluctuations in pressure, which is crucial for safe operation in high-pressure contexts. Using increments of 1/5 inch allows for a fine resolution that would effectively capture these minor variations. This level of sensitivity is particularly important as it provides operators with the ability to observe and respond to small changes in pressure, which can be critical in preventing system failures or accidents. The other options—1/4 inch, 1/10 inch, and 1/2 inch—either do not offer the same level of detail or might be too coarse for the safe operation of high-pressure systems. Therefore, selecting 1/5 inch as the minimum calibration increment strikes the right balance between precision and practical usability for a gauge measuring up to 5 psig.
