Very good IMU ADIS16445AMLZ is not equipped with pressure sensor, so i had to use the external sensor. Also i used the external accelerometer to backup if the Z acc will go over range. Once i got the different meanings from these accelerometers. It was at the same time when sharp but small pressure wave entered the compartment.

Can it affect the readings?

acceleration in "g", pressure units are arbitrary, actual pressure step was 500 Pa (or 0,072 PSI).
