QBecause they still have not got the sample, so he have to use the part (whose X
axis was damaged) to do the other test. he found the Static error is quit large
(Please see attached). Is that normal? Will the damaged X axis interfere other
axis's performance? he does not found large ripple on the power supply.
AWhile we calibrate the gyroscope bias in the factory, we have seen that the
bias can drift when the parts are exposed to abnormal environmental conditions
(temp cycles, package stress). It is also possible that the electrical over
stress, which destroyed the x-axis gyroscope response, is influencing this
behavior. The good news is that the custom can preserve the overall
calibration by doing a single-point bias correction.
Application now AN-1041 covers how to do the single-point bias correction.
