Tips for Taking Measurements

You should always take measurements using the machine
•
operating mode that is typical for that machine (using a
typical load and running speed). This will ensure that the
loads on the components, such as bearings, are the same as
those that define their wear. For multi-operating mode
machines it is best to take measurements when the loads on
the bearings are at a maximum and to take all future
measurements in the same mode.
When taking the measurement, try not to lean on the
•
machine and do not put heavy objects (e.g. heavy tool
boxes) on it since this will change the vibratory behavior of
the machine.
If there are machines operating nearby that might affect the
•
vibration of the machine you are measuring, stop those
surrounding machines if possible.
