<DIV>Dear all,</DIV>
<DIV> </DIV>
<DIV>I agree with <EM>Apostolos Agalos. </EM>I also think the Constant should be
derived from the<BR>multiplication of the Sensitivity with A0.</DIV>
<DIV> </DIV>
<DIV>I think the following method should be right when calculating the
CONSTANT.</DIV>
<DIV> </DIV>
<DIV>CONSTANT=A0×Sensor Sesivity × Digitiser Gain × 2*pi</DIV>
<DIV> </DIV>
<DIV>here A0 is in rad/sec Unit,Digitiser Gain is V/ms.</DIV>
