Dear all,

I agree with Apostolos Agalos. I also think the Constant should be derived from the
multiplication of the Sensitivity with A0.

I think the following method should be right when calculating the CONSTANT.

CONSTANT=A0×Sensor Sesivity × Digitiser Gain × 2*pi

here A0 is in rad/sec Unit,Digitiser Gain is V/ms.
