2. MaxiMet contains a 2 axis compass and magnetic field sensing module using Magneto Inductive MI sensors The sensor changes inductance by 100 over its field measurement range It incorporates a temperature and noise stabilized oscillator counter circuit The compass has a high degree of azimuth accuracy MaxiMet uses the internal compass to electronically sense the difference in the earth s field from the system s magnetic field then an on board microprocessor electronically subtracts out the system s magnetic fields reporting highly accurate compass readings Wind direction data is corrected for the orientation of the sensor The output of the wind direction is relative to magnetic North The MaxiMet compass is calibrated at Gill Instruments before the unit is delivered Prior to installing MaxiMet it is suggested that for best accuracy a declination figure should be entered Compass Declination Declination is the magnetic declination the angle between Magnetic North and True North in degrees This is a correction factor that is added to the magnetic north heading from the compass Map and declination figures in decimal figures can be obtained from http www geosats com magdecli html http www nqdc noaa gov qeomag declination shtml MaxiMet Page 7 Issue 4 Doc No 1957 PS 001 August 2015 Gill Instruments Ltd Solar GMX301 GMX501 MaxiMet uses a high quality Hukseflux LPO2 second class Solar Radiation Pyranometer wh
