A 300 psi water gauge on a water tank tested against a calibrated gauge must be replaced if the reading is which of the following:

Explanation:
Gauges must read within an established tolerance when checked against a calibrated standard. If the gauge under test indicates a higher pressure than the calibrated reference by a amount that exceeds that tolerance, it’s considered out of calibration and must be replaced. In this scenario, a reading that is 10 psi higher than the calibrated gauge crosses the replacement threshold, signaling the instrument is not trustworthy for safe operation. The other deviations do not exceed that threshold, so they do not require replacement.
