For the best measurements, use these guidelines:
•
Push  and position the Meter perpendicular to the test surface.
•
Push the sensor tip onto the test surface, on solid metal, and as close to the bearing as possible
until the green LED turns on.
•
Hold Meter in position with a consistent force until the green LED turns off. The test results show
on the display.
Severity Scale
No repair action is recommended.
No immediate repair action is required. Increase the frequency
of measurements and monitor the condition of the machine.
Have a knowledgeable vibration technician conduct
more advanced tests at the earliest opportunity. Consider
maintenance action at the next planned downtime or
maintenance period.
Have a knowledgeable vibration technician conduct more
advanced tests as soon as possible. Consider immediate
shutdown of the machine to make repairs and prevent failure.
Crest Factor + (CF+)
The Meter operates with a proprietary algorithm called Crest Factor + (CF+). To
make interpretation easy for the user, the CF+ value is shown in a range from
1 to 16 in the severity scale. The higher the CF+ value is, the more the bearing
damage.
The CF+ value shows for every measurement in the Bearing field on the Meter
display. Push  and  to toggle between the CF+ value and the high frequency
vibration level in units of acceleration.
