We plan to utilize the IMU product MPU-9250. And now, we are testing.
However, we face a problem. Acceleration scale of MPU-9250 are sometimes suddenly changed half. For example, when we were sensing the earth gravity 1G, sometimes output value was suddenly changed to 0.5G. Once this improper scale problem occurs, the problem remain for several hours, and then it is suddenly changed back to the original scale.
We are setting the scale of acceleration +/-16G. Thus, this problem can mean that acceleration scale was changed to +/-32G. However, MPU-9250 does not have this setting. (MPU-9250 scale setting: +/-2G, +/-4G, +/-8G, +/-16G)
This problem affects all of three axis in accelerometer. While, this has nothing to do with the outputs of gyro sensor.
Do you have any knowledge or advices about this scale changed problem?
