Problem 

Solution 

agree 

due to signal filtering. The indoor and outdoor 

humidity sensors should agree within 10 % (the 

sensor accuracy is ± 5 %) 

2.

 

Perform a humidity calibration (reference 

Section 2.1) 

Relative pressure does not agree with 

official reporting station 

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 

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. 

Time is incorrect 

Make sure your time zone and daylight savings time 

setting is correct. 

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. 

Moon phase is not correct 

Check your calendar date and make sure it is correct 

Display console contrast is weak 

Replace console batteries with a fresh set of batteries.
