Vibration sensor is placed on engine to measure how engine is moving in 
space.
Prop imbalance will make engine move in bigger circle.
So mayny Millivolts are genrated per vibration severity.

Relative location of heavy spot is  signaled by photo cell, or strobe light 
flash as heavy spot passes and polarity changes.  Up-down = plus-minus.

The prop's static weigh slugs can be adjusted or large area washers can be 
bolted to spinner bulkhead to counterbalance the heavy spot.

How much depends weigh depends on how much imbalance there was to begin 
with.

Common to have 10-30 grams of weight for a momento of 100-200 inch pounds.
