occur, for example, with a nonstandard installation, such
as a lightweight aerobatic propeller on an engine that
normally carries a metal constant speed propeller or on a
racing propeller that has an extension between the engine
and propeller. In cases like these, use the next-lower
horsepower range than the one normally used.
Auto Correction Feature - This feature allows the Vibrex
unit to use the response of the rotor or propeller being worked to
change the sensitivity and phase values, as follows:
Generally, a propeller responds according to its inherent
sensitivities, but the user always has the ability to put any
weight, anywhere, and the Vibrex unit can learn the response
to this adjustment and correct, automatically, the sensitivity
and phase sense.
The Auto Correction feature works based on a set of
readings with a known change, at a known location between
those readings.
When the final solution is given, Auto Correction is
automatically shut off, since additional changes would be
minimal and not worth the additional time.
If the user is not weighing the weights placed on the propeller, it
is best to leave the Auto Correction feature <OFF>. There is no
way of knowing how to correct an unknown quantity.
NOTE: This type Auto Correction feature is only available
with the Propeller Balance Setup screen and its associated
operations. A similar, but slightly different Auto Correction
feature is available for the Enhanced Vibrex 2000 Plus
Helicopter Balance.
