Dual Accelerometers Cross Axis Sensitivity

I'm currently looking at the use of ADXL206 Dual accelerometer but I'm not sure on the definition of the Cross-Axis sensitivity.

Taking the same Axis convention as the datasheet (Sensing in X and Y, Z = perpendicular to (X,Y) plan)

Fig 10 and Fig 13 of the datasheet shows the Cross Axis sensitivity (CAsens) vs. the Z-Axis but I'm not sure on how to use this coefficient.

Considering for example the acceleration measurement on the X axis, how shall I estimate the Cross-Talk with the acceleration components in the (Y,Z) plan?

 

  1. CAsens * AccZ
  2. CAsens*(AccY^2+AccZ^2)^0.5

 

Thanks for your help ,

 

Stephane.
