Offset: This field will only appear after “Tracking Planes” above is set to 2 and the field is
exited. This field is used to define the optimum distance between multiple blade planes. The
analyzer will use this distance to properly position the groups of blades.
Blades: The blade names will default to those defined previously in the setup. If a change is
required, change the blade name to reflect the blades in passing order staring with the blade
that is over the nose when the tach and interrupter are aligned. This will be the name used in
the track display and when viewing available adjustments.
Plane: This field will only appear after “Tracking Planes” above is set to 2 and the field is
exited. This field is used to identify how the blades will be grouped. Blades flying in the
same plane require identical “Plane” entries.
