Fluke 810 User Manual page 77

A Top/Bottom, Side, or End selection is for
horizontal mountings. A Front/Back, Side, or End
selection is for vertical mountings. For vertical
mountings, the first time you take a
measurement, decide which side of the motor
will be called the front and back. Mark the motor
accordingly for use in future measurements.
10. Use the Dial to select the correct position of the
Sensor at that location: Top/Bottom, Side, End,
or Front/Back. Depending on the Sensor
orientation selection, another screen appears.
The Tester uses the driveshaft (depicted as a
thick red line in the display) as the primary frame
of reference. Orient the Sensor to the driveshaft
using the Sensor cable where it exits from the
Sensor, telling the Tester whether the cable is
parallel or perpendicular to the shaft.
Note
The first time you take a measurement, draw or
paint a line on the machine to indicate the
Sensor measurement location. Use an arrow to
indicate the Sensor orientation. If you take
measurements at exact same locations and
with exact same Sensor orientations, you can
push Use last orientations/locations. This will
bypass the location and orientation screens and
take you directly to the data collection screen.
How to Measure Vibration
11. Use the Dial and select the alignment of the
Sensor cable as it relates to the machine
driveshaft. The red line (or dot) on the screen
graphic represents the driveshaft. After you
select the orientation, the measurement screen
appears.
