1 The pressure as measured by the probe is what is referred to as atmospheric pressure and is not corrected to sea level.
Weather station pressures are reported at sea level and commonly referred to as mean sea level pressure. As a result the
probe will not read the same as most household or professional barometers or weather station reports (which are
compensated) unless reported at sea level. In order to compare the pressure results obtained from the probe barometer
and these compensated barometers, it is necessary to first compensate the pressure reported by the probes
mathematically.
