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 22.
Figure 6 identifies the parts of the measurement display.

Push  and  to toggle the display selection between
Bearing and Overall Vibration measurements. In the
Bearing selection, push  and  to toggle the display units
between CF+ and acceleration. In the Overall Vibration
selection, push  and  to toggle the display units between
acceleration, velocity, and displacement.
