Indoor and Outdoor Temperature do not
agree
Allow up to one hour for the sensors to stabilize due to
signal filtering. The indoor and outdoor temperature
sensors should agree within 4 °F (the sensor accuracy is
± 2 °F)
Indoor and Outdoor Humidity do not
agree
Allow up to one hour for the sensors to stabilize due to
signal filtering. The indoor and outdoor humidity sensors
should agree within 10 % (the sensor accuracy is ± 5 %)
Humidity reads – instead of a value. If the humidity falls outside the measurement range (10
to 99%), the humidity will display “—“
Absolute pressure does not agree with
official reporting station
You may be viewing the relative pressure, not the
absolute pressure.
Select the absolute pressure. Make sure you properly
calibrate the sensor to an official local weather station.
Reference Section Barometric Pressure5.5 for details.
The barometer is only accurate to ± 0.08 inHg within the
following relative pressure range: 27.13 to 32.50 inHg,
which corresponds to an altitude of -2,200 to 2,700 feet.
At higher altitudes, expect some non-linearity or error.
Rain gauge reports rain when it is not
raining
An unstable mounting solution (sway in the mounting
pole) may result in the tipping bucket incorrectly
incrementing rainfall. Make sure you have a stable
mounting solution. Move the rain gauge from the pole
mount to a flat, stable mount (fixed, flat structure).
Software does not recognize weather
station
Make sure the USB cable is plugged in and recognized
by the PC operating system. If it is not recognized, try a
different USB connection. Avoid USB hubs.
Barometer graph flashes. Can I turn this
off?
No, this feature prevents burn in of the display monitor.
Wind speed appears low Average wind speed may have the appearance of low
wind. Try switching the display to wind gust.
Display console is difficult to read Change the display contrast level as described in
Section 5.1.
Replace the batteries in the console with a fresh set of
batteries.
Can the lamp be turned on all of time? No, to prevent the bulb from burning out, it can only turn
on temporarily.
The forecast icon is not accurate 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.
