If a gauge deviates by more than 3 percent from full scale, the gauge should be:

• A. Recalibrated or replaced
• B. Repaired and tested
• C. Kept in service
• D. Disposed of

Answer: (A)

This question tests understanding of instrument accuracy and calibration practices. When a gauge reads off by more than a small tolerance from its full-scale indication, it’s not reliably measuring, so action is needed to restore trust in the readings. The correct approach is to recalibrate the gauge so its readings align with the true values, or replace it if recalibration can’t bring it within specification. Repaired and tested isn’t the standard path here because repairs don’t guarantee the gauge will be within the required accuracy; keeping an out-of-tolerance gauge in service risks operators making wrong decisions, and disposing of the gauge is unnecessary when recalibration or replacement can fix the issue.
