Hello Everyone, i Please need HELP! I have a technical question regarding the APM 1 Mega Barometric pressure sensor. How do i know if the barometric pressure sensor is working right? I get a strange reading on the VSI, the indicator mouves up and down +/- 3-4 and some times it stays at zero and then it goes up and down again!!!! I am testing the apm on the mission planner and checking all the other sensors and seams like they are working fine, nothing moves if i don't touch the apm, what kind of reading are we suopposed to get from the Mission Planner pressure sensor VSI gauge? Is it normal?
Or does it need to be steady reading like always zero? Or the indicator from the vsi pressure sensor oscillates a bit.Please respond!!!
Thank you.

I'm seeing the same problem on my new APM2 with MP 1.1.55 and V2.5 firmware...would love to know if this is normal also.
Have you tried erasing eeprom?? connect to MP through USB and in terminal go to setup/ erase. repeat a couple of times and upload the firmware again.
