If a gauge is not accurate within 3 percent of the scale, what action is required?

• A. Recalibrate or replace
• B. Ignore
• C. Operate as is
• D. Recalibrate only

Answer: (A)

Gauges used to measure stored oil must be dependable, with readings that fall within a small tolerance of the full scale. When a gauge isn’t accurate within 3 percent of the scale, the reading can no longer be trusted to represent the true volume. That’s why the proper action is to bring the instrument back into spec by recalibrating it, or to replace it if recalibration cannot restore accuracy. Recalibration aligns the gauge reading with a known standard, correcting systematic drift, while replacement addresses faults that cannot be fixed through adjustment alone. Ignoring the discrepancy or continuing to operate with an out-of-tolerance gauge risks incorrect inventory records, potential safety issues, and regulatory problems. Recalibrating only might not suffice if the instrument is faulty, so having the option to replace ensures reliable measurements.
