About Measurements

The Meter measures bearing health and the overall
vibration condition of a machine. Three types of
measurements are available: bearing vibration, overall
vibration, and temperature. Vibration measurement units
are user-selectable. More information about how to
change these units is on page 9.
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.
In most applications the default RPM setting of >600 RPM
is correct. You must change this range for low frequency
applications where the shaft rotation is <600 RPM. A
severity scale does not show on the display when the
setting is <600 RPM. More information about how to
change the RPM setting is on page 23.
