Problem Solution
not agree
during indoor
testing temperature. The indoor and outdoor temperature sensors
should agree within 4 °F (the sensor accuracy is ± 2 °F).
If these values still disagree, use calibration offsets for
one or both sensors (see section 6.9.3) to adjust to a
known good reference temperature.
Indoor and
Outdoor
Humidity do
not agree
during indoor
testing The procedure here is that same as for outdoor/indoor
temperature. The sensors should agree within 10 % (the
sensor accuracy is ± 5 %)
If these values still disagree, use calibration offsets for
one or both sensors (see section 6.9.3) to adjust to a
known good reference humidity.
Relative
pressure does
not agree with
official
reporting
station Relative pressure refers to sea-level equivalent
temperature and should generally agree closely with the
official station. If there is a disagreement, make sure you
are not looking at absolute pressure, in particular if your
station is not near sea level. Also check at different times
due to occasional delays in updates to the official station.
Redo the pressure calibration procedure described in
section 6.9.3.
The barometer is only accurate to ± 0.09 inHg (3 hPa)
within the following relative pressure range: 20.67 to
32.50 inHg (700 – 1,100 hPa), which corresponds to an
altitude of 9,000 ft. (2,750 m) down to 2,500 ft. (750 m)
below sea level. At higher altitudes, you should expect a
possible lesser accuracy and non-linearity effects in the
error (the calibration offset only allows for a partially
linear correction).
Data not
reporting to
Wunderground.
com Confirm your station ID is correct. The station ID is all
caps, and the most common issue is substituting a capital
letter O for a 0 (zero) or vice versa. Please note the digit
0 can only occur in the last part of the station ID (which
is a station number in a city). Example, KAZPHOEN11,
