The customer met a problem about ADIS16405.
I tried by ADIS16350 and met the same problem. As below figure shown, the
offset value for Accelerometer is always 0.


This routine only calibrates the gyroscopes because the accelerometers cannot
all be zero at the same time.  They will be somewhere between +1g and -1g when
sitting still, depending on their orientation with respect to the earth’s
gravity. The ADIS16209 zeros the inclinometer registers for a reference set
point.  In the ADIS1635x, 36x and 40x products, the auto-null is for the
gyroscopes only.
