Pixhawk baro problem

witkuk · July 17, 2014, 10:18pm

Hi,

When I run terminal baro test, altitude readings change rapidly in a few seconds after calibration. See my 20 minute baro test in attachment. It looks like a bad temperature compensation. Baro is more stable after 1 hour Pixhawk being connected to USB port - constant 45.9 temperature (see 2nd attachment).
Do You think I have faulty baro in my Pixhawk?

PS. Firmware Arducopter v3.1.5, room temp. 26C
