Problem
Relative pressure
does not agree with
official reporting
station.
Time is incorrect.
The forecast icon is
not accurate.
Moon phase is not
correct.
Display console
contrast is weak.
Solution
1. You may be viewing the relative
pressure, not the absolute pressure.
2. Make sure you properly calibrate the
barometer to an official local weather
station (reference Section 2.1)
3. The barometer is only accurate to ±
0.08 inHg
relative pressure range: 27.13 to
32.50 inHg, which corresponds to an
altitude of -2,200 to 2,700 feet. At
higher
non-linearity error.
Make sure your time zone and daylight
savings time setting is correct.
The weather station console must run for
several days to trend barometric pressure.
The weather forecast is an estimation or
generalization of weather changes in the
next 24 to 48 hours, and varies from location
to location. The tendency is simply a tool for
projecting weather conditions and is never
to be relied upon as an accurate method to
predict the weather.
Check your calendar date and make sure it
is correct.
Replace Base Station batteries with a fresh
set of batteries.
