A good diagnosis begins with good and repeatable data!
Remember that when you are measuring vibration data with an accelerometer, you are actually measuring both the vibration forces produced by the machine, and the effect of the machine’s structure on these forces. For the same reason a doctor places a stethoscope on your chest instead of on your big toe when he wants to listen to your heart, always mount your sensor on a rigid structure as close to the bearings as possible. In order to essentially remove the effects of the structure from trend data, always be sure to mount your sensor in the same location test after test; preferably on a permanently installed stud mount.
