the bearing
housing
Check the value of adjacent bearings.
Are the signals from these bearings similar to the tested
bearing?
Locate the signal source. The reading can be caused by
cross talk from other defective bearings or disturbances
from other mechanical shocks. If possible, isolate the
source of disturbance and test again.
