Vibration axis
Environmental vibrations are normally measured in two horizontal planes
(front/back and left/right) and one vertical plane. This means that complex
vibration phenomena are reduced to three axes (X, Y, Z), for easier observation.
The axes are defi ned as follows (facing the vibration source).
Horizontal front/back:
X
Horizontal left/right:
Y
Vertical: Z
