5.1.2 Set Date

1. Change Year. Press the SET key to set the year. The year will begin flashing. Press the + key

or MIN/MAX key to change the year setting.

2. Change Month. Press the SET key to set the month. The month will begin flashing. Press

the + key or MIN/MAX key to change the month setting.

3. Change Day. Press the SET key to set the day. The day will begin flashing. Press the + key

or MIN/MAX key to change the day setting.

5.1.3 Set Indoor Temperature and Outdoor Temperature Units

Change Indoor Temperature Units. Press the SET key to set the indoor and outdoor temperature

units. The indoor and outdoor temperature will begin flashing. Press the + .to alternate the display unit

between °C and °F.

5.1.4 Set Barometric Pressure

Note: The weather station 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 if you were 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

around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are

considered high pressure and relative pressure measurements less than 29.92 inHg are considered low

pressure.

To determine the relative pressure for your location, locate an official reporting station near you (the

internet is best source for real time barometer conditions, such as Weather.com or Wunderground.com),

and set your weather station to match the official reporting station.

1. Pressure Units. Press the SET key to set the pressure units. The pressure units will begin

flashing. Press the + key to alternate between in Hg and hPa.

2. Relative vs. Absolute Pressure Display. Press the + key to alternate the display between

relative (rel) pressure and absolute (abs) pressure.

3. Relative Pressure Calibration. Press the SET key to set the relative pressure. The relative

pressure will flash. Press the + key or MIN/MAX key to change the relative pressure.

4. Pressure Threshold. Press the SET key to change the pressure threshold. The pressure

threshold will be flashing. Press the + key to adjust the pressure threshold from 2.0 to 4.0

hPa/hr (the default is 2 hPa/hr).

5. Storm Threshold. Press the SET key to change the storm threshold. The storm threshold will
