If item "1" shown in the illustration is a compound gage indicating zero psig and the water level in the bilges is one foot high, the unit is _______________. Illustration GS-0153
AI Explanation
The correct answer is D) not turned on.
If the compound gauge is indicating zero psig (pounds per square inch gauge) and the water level in the bilges is 1 foot high, this suggests that the gauge is not turned on or functioning properly. A properly functioning gauge should indicate the actual pressure in the system, not zero. The fact that the water level is 1 foot high also suggests the gauge is not properly monitoring the system. Therefore, the correct answer is that the gauge is not turned on and should not be used in this condition.
The other answer choices are incorrect because they do not accurately describe the situation based on the information provided. The gauge is not in an oil discharge mode, not processing bilge water, and is not necessarily damaged - it simply appears to not be functioning properly.
