The weather station calibrates barometric pressure based on its location over a period
to generate an accurate, personal forecast. Please allow 7-10 days for barometer
calibration.
•
The station samples the barometric pressure every twelve minutes. These samples are
averaged hourly and daily then stored in nonvolatile memory. The three-hour pressure
icon change is based off the last four average hourly readings.
•
IMPORTANT: As the weather station builds memory, it will compare the current
average pressure to the past forty day average pressure for increased accuracy. The
longer the weather station operates in one location the more accurate the forecast
icons will be.
BAROMETRIC PRESSURE
•
The forecast station, not the outdoor sensor, reads the Barometric Pressure.
•
The numeric pressure value adjusts automatically as the forecast station reads changes
in air pressure.
•
the unit can select the pressure unit of measure (InHg is common
in the USA) and set the actual pressure number on your station.
•
La Crosse Technology products will not read pressure correctly above 6200 ft. in
elevation.
•
Loss of Pressure is often a power-related problem, and it can be resolved by following
these steps:
o
Remove power from the display for 2 hours. Press any button 20 times with power
removed.
o
Install fresh batteries into the display unit. After 5 minutes, check to see if the
pressure and indoor temperature are working correctly.

PRESSURE HISTORY
•
The far right set of bars is the current pressure or the “zero mark”.
•
Each set of bars to the left represent the change from the zero mark for that period.
There are a limited number of bars for each period.
•
Each bar on the graph represents a value of 0.03 hPa (Hecto Pascal).
•
Occasionally a low front will come through that drops the pressure several bars in a
short time.
