13. Indoor Humidity Calibration (default is measured outdoor humidity). Press the SET key to
adjust the outdoor humidity. Press the + key or MIN/MAX key to adjust the humidity up or
down in 1% increments.
Reference Section 4.2.2 Setting Calibrated Humidity for more details on this feature.
14. Outdoor Temperature Calibration (default is measured outdoor temperature). Press the
SET key to adjust the outdoor temperature. Press the + key or MIN/MAX key to adjust the
temperature up or down in 0.1 degC (0.18 degF) increments.
To view the uncalibrated value, press the ALARM key while the temperature is flashing.
Reference Section 4.2.3 Setting Calibrated Temperature for more details on this feature.
15. Outdoor Humidity Calibration (default is measured outdoor humidity). Press the SET key
to adjust the outdoor humidity. Press the + key or MIN/MAX key to adjust the humidity up
or down in 1% increments.
To view the uncalibrated value, press the ALARM key while the humidity is flashing.
Reference Section 4.2.2 Setting Calibrated Humidity for more details on this feature.
16. Barometric Pressure Display Units (hPa or inHg). Press the SET key again to toggle the
pressure units between hPa or inHg.
17. Relative Pressure Calibration (default is 29.92 inHg). Press the SET key to adjust the
relative barometric pressure. Press the + key or MIN/MAX key to adjust the relative
barometric pressure up or down. Reference Section 4.2.1 Setting Barometric Pressure for
more details on this function.
18. Pressure Threshold Setting (default level 2). Press the SET key again to adjust the
pressure threshold setting. Press the + key or MIN/MAX key to adjust the pressure
threshold up or down. Reference Section 4.5.5 for more details on this function.
19. Storm Threshold Setting (default level 4). Press the SET key again to adjust the storm
threshold setting. Press the + key or MIN/MAX key to adjust the storm threshold up or
down. Reference Section 4.5.4 for more details on this function.
4.2.1 Setting Barometric Pressure
The display console displays two different pressures: absolute (measured) and relative (corrected to
sea-level).
To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-level) is generally higher than your
measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but
the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure
