Question 567General Subjects - Assistant Engineer

The correct answer is B) The unit being tested is operating normally. A portable hand-held vibration meter is used to measure the vibration levels of equipment, such as motors or machinery. The vibration levels indicated by the meter can provide information about the operating condition of the equipment. If the vibration levels are within the normal, acceptable range, it indicates that the equipment is operating normally. This is what answer B) is referring to. The other answer choices are incorrect because they suggest the meter can identify specific issues with the equipment, such as bad bearings, a bad stator, or a bad rotor. While vibration analysis can sometimes help diagnose these types of problems, a basic handheld vibration meter is primarily used to assess the overall vibration levels, not to pinpoint the exact cause of any issues.
