How to calibrate the airspeed?

Tom
Hi,all!
    I wanna measure airspeed with my MS4525D.However,the airspeed measured doesn't show the real value.It displays 0m/s when the real below 10m/s.And it displays 16m/s when the real value is 30m/s.
    I know that we can set the parameters for the ms45xx module.Such as "ms45xx_airspeed_scale","ms45xx_pressure_offset",etc.But,how can I get the calibrated parameters for my MS4525D? I have searched the wiki and found nothing about the calibration for the airspeed.
    Thank's a lot!

Hi Tom,

there is currently no automatic procedure to calibrate an airspeed sensor.
Did you set the sensor type and pressure range that your sensor has correctly?
See http://docs.paparazziuav.org/latest/module__airspeed_ms45xx_i2c.html

Hope that helps,
Felix
