Enter the Trial Weight Manually
Follow these instructions to manually enter the trial weight you are attaching to
the machine. A negative number can be entered if trial weight is removed, instead
of added. Trial weights are typically attached at 0° (the trigger reference). Unless
you wish the data collector to estimate a trial weight, the Radius entry is not
necessary, so long as you position the trial, correction, and trim weights at the
same radius.
1. On the machine, carefully attach the precise weight at the precise angle and
radius specified.
Balancing results depend greatly on the precision of your measurements
and actions.
2. Use the Up/Down arrows to select the parameters and the Right arrow to
enter trial weight, angle, or radius value by using the numeric key pad.
In the Mass parameter, enter the trial weight. Enter rotor mass supported
in this plane (in the Weight Units specified on the Balance Setup screen).
Use total rotor mass for single plane and 50% of mass for two plane.
3. In the Angle parameter, enter the location (in degrees) of the trial weight
on the rotor.
The trial weight’s Angle placement is typically zero. The angle is measured
from the reference mark in the direction specified in the Movement
parameter in the Balance Setup screen.
See Set Up the Balancing Parameters on page 20 for additional
information.
4. In the Radius parameter, enter the radius of the trial weight.
5. Press OK.
