Q
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.
A
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.
