press START. The following screen will be displayed:
Use the ▲ and ▼ keys to select the proper adjustment point
and then press ► to toggle between <INCL> and <EXCL> to
include or exclude the adjustment point from the solution.
The exact setting can also be edited by simple typing in a
number on the numeric keyboard.
NOTE: Since the left side context keys are assigned to
other functions, numeric entry is done differently on this
screen than is normally done. Entry is started by typing in
the digits. If a mistake is made, type 0’s until the field is
cleared then you can start again.
RESPECT LIM: <YES> context key. Most helicopter
manufacturers will publish limits for certain adjustment
types, e.g. maximum tab bends or weight added. By default,
the EV2K+ will try to respect these limits. If the solution
shows high predicted vibrations (see paragraph 5.6.2 (9.)),
then this option can be set to <NO> to see if there is a
reasonable solution available without respecting limits.
CAUTION: This option should be used with extreme care
and for “what if” studies only. It is never recommended to
exceed manufacturer’s limits. The mechanical condition of
the component should be checked first before applying any
adjustments if the limits are greatly exceeded.
5.6.3 Auto-Correction
The Enhanced Vibrex 2000 Plus uses balance adjustment
“charts” specific to:
Helicopter model
Balance component
Flight state or regime
Vibration sensor mounting location and direction (as
stated in Application Guides)
