Which action should be performed to verify the accuracy of discharge gauge readings?

• A. Calibrate against a known reference gauge
• B. Turn off the gauge and restart
• C. Ignore the gauge readings during testing
• D. Record readings without calibration

Answer: (B)

The main idea is to confirm the gauge is functioning properly and not giving a stuck or erroneous reading. Turning the discharge gauge off and back on provides a quick reset that clears transient faults and reinitializes the measurement circuit. After the restart, you can observe whether the gauge reads and responds normally, which helps verify that the readings you see during the test are trustworthy. If the value still seems wrong after resetting, you’d move on to a more thorough check, such as calibration against a known reference gauge, to verify accuracy. Calibrating against a reference gauge is a proper verification step but is typically done as a deeper follow-up when a restart indicates potential issues. Ignoring readings or recording without calibration won’t establish accuracy and could hide instrument faults.
