Pressure Compensation
If altitude differs significantly from sea level (default), a pressure compensation should
be made.
MF_PRESSURE xxxx Altitude m (ft) Atmospheric
pressure hPa (psi)
where: xxxx = pressure in hPa.
Example of setting desired pressure:
>MF_PRESSURE 900
MF_PRESSURE=900
>
To save the setting, give command:
MAIN_SAVE F
0 (sea level) 1013 hPa (14.69 psi)
500 m (1640 ft) 954 hPa (13.84 psi)
1000 m (3281 ft) 899 hPa (13.04 psi)
1500 m (4921 ft) 845 hPa (12.26 psi)
2000 m (6562 ft) 795 hPa (11.53 psi)
2500 m (8202 ft) 747 hPa (10.83 psi)
3000 m (9843 ft) 701 hPa (10.17 psi)
Temperature Setting
MF_TEMP xxx
where: xxx = ambient temperature (°C) x 10.
Example of setting desired temperature (25 °C):
>MF_TEMP 250
MF_TEMP=250
