Propeller Balancing
Vibrex 2000 and Vibrex 2000 Plus User Guide 85
Continue toward a permanent weight installation, for the Vibrex 2000 and
Vibrex 2000 Plus as follows:
1. Press the
INSTALL PERMANENTLY
context key from the propeller
balance quality screen.
2. If a radius change will occur for the installation of the permanent
weight, press the
CURRENT RADIUS
context key.
NOTE: The radius is the number of inches (or any unit) from the
center of rotation. An easy way to determine the radius is to
measure the diameter of the spinner when it is removed and divide
that number by 2.
3. Enter the trial weight radius, using the numeric keypad.
4. Press the
PERMANENT WEIGHT
context key and enter the
permanent weight radius, using the numeric keypad.
5. Press
START when both values are correct.
The resulting solution displays the weight required at a single balance
point at the permanent radius.
5.4.4.1 If Unable To Use Weight Azimuth
The user may not be able to use the azimuth of the balance weight, for
clearance or other reasons, or the weight may be too much for a single-
weight addition point. In these cases, do the following procedures:
1. Press the context key labeled AT [XX:XX].
2. Press the
SPLIT WEIGHT
context key.
3. Enter the angle or angles available for weight addition.
CAUTION: The user must enter two weight points one on either
side of the single-weight location in order for the solution to result
in the same IPS reading.
The Vibrex unit calculates the required weight on each point.
NOTE: As the weight is split farther apart, the required weight
becomes greater because of the lower combined arm of the weight
from the center of rotation.
