Oscillation in IMUACC

[pinzigu]

Hello!

I am currently doing the static calibrations with my AQ
Can someone please have a look at my chars and tell me if it looks ok?
I got some strange oscillations at low temps in IMU_ACC

I wanted to include the image here but I am not allowed yet
It can be found in the RC groups AQ thread (last page)

btw: is there a whitelist-page for image hosting

thank you in advance

This is quite normal for the analog boards. It happens when the board thaws and its contracting.

The only way to get rid of it is to try and get the thawing to happen slower. Can you show us the temp curve?

In spite of the noise, data should still work. The amplitude is a big bigger than what I normally see, but shouldnt be a problem in the calibration.

Thank you for the response!

here is the temp curve:
