Daily question for the activity (single-choice question): If pressure gauge failure is suspected, the most reliable method is ( ), which can determine whether the pressure gauge is malfunctioning. A. Close the outlet valve and then open it again to see if the pressure gauge returns to zero. B. Replace it with several new pressure gauges and compare the readings. C. Remove the current pressure gauge and reinstall it to compare the readings. D. Replace the pressure gauge gasket and compare the readings. Answer: B. Replace it with several new pressure gauges and compare the readings. Please participate actively to win prizes. +5 points for correct answers, +2 points for participation. One time per person only.

If there is suspicion that a pressure gauge is malfunctioning, the most reliable method is (B) to replace it with several new pressure gauges and compare the readings, thereby determining whether the original gauge is faulty.
Answer B should be the best; the others are also acceptable
If there is suspicion that the pressure gauge is malfunctioning, the most reliable method is ( C ), which can determine whether the pressure gauge is defective. A. Close the outlet valve and then open it again to check whether the pressure gauge returns to zero. B. Replace several new pressure gauges and compare the readings. C. Remove the pressure gauge and reinstall it to compare the readings. D. Replace the pressure gauge gasket and compare the readings
My answer is B: replace the pressure gauge and compare the values
If there is suspicion that the pressure gauge is malfunctioning, the most reliable method is ( B ), which can determine whether the pressure gauge is faulty. A. Close the outlet valve and then open it again to check whether the pressure gauge returns to zero. B. Replace several new pressure gauges and compare the readings. C. Remove the pressure gauge and reinstall it to compare the readings. D. Replace the pressure gauge gasket and compare the readings
B. Replace several new pressure gauges and compare the readings
This question is quite insightful. The answer is B. If only the pressure gauge manual valve is closed without releasing the pressure, the pressure gauge should not return to zero. Removing the pressure gauge and then reinstalling it has the same effect as replacing the gauge gasket, but it should be determined by whether the pressure gauge returns to zero, rather than by comparing pressures.
If there is suspicion that the pressure gauge is malfunctioning, the most reliable method is ( ), which can determine whether the pressure gauge is faulty. Answer: A. Close the bleed valve, then open it again, and check whether the pressure gauge returns to zero
B. Replace several new pressure gauges and compare the readings
Turn it off and then on again, to check whether the pressure display is accurate
