Preparations

Note

Determine the orientation of horizontal planes in accordance 
with the applicable specifi cations.

Vibration pickup placement and connection 

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 

Z axis 

Vibration

source 

Vibration pickup
