Yes, I don’t know why the measurement value of the barometer is negative. I think all the cases online are positive. How should I troubleshoot this issue?
What I saw on the website ，But my date display is completely wrong
Here are the pictures on the website
Is the barometer being effected by airflow some how? Maybe some cover or foam over the sensor might help.

I covered it and added a cover.
Was this test flight performed in close ground proximity right (ground effect) ? considering you have a rotor diameter of 6m and looking at the gps altitude:
this might be affecting baro readings.

The reason for the incorrect parameters of the barometer has been identified, which is caused by the airflow of my helicopter rotor, and the impact range is very large.
My current solution is to install millimeter wave radar, RTK, and turn off GPS.
My parameter changes:
EK3-SRC1-POSZ=3
GPSTYPE2=1
RNGFND1-TYPE=27
RNGFND1 ORIENT=25
RNGFND_1 MAX CM=1000
RNGFND_1 MIN CM=20
ERIAL2BAUD=115 (115200)
SERVAL2PROTOCOL=9
My goal is to use millimeter wave radar data primarily when the helicopter is within a height of 10 meters from the ground. When the aircraft is over 10 meters above the ground, RTK data is the main method. Completely unsuitable for barometers.
I don’t know if this setting can solve this problem
Yes, it’s not flying very high, within one meter of the ground
