WEATHER FORECAST
The weather forecasting feature is
estimated to be 75% accurate. The
weather forecast is based solely upon the
change of air pressure over time. The
WS-7213U averages past air-pressure
readings to provide an accurate
forecast—creating a necessity to
disregard all weather forecasting for 12-
24 hours after the unit has been set-up,
reset, or moved from one altitude to
another (i.e. from one floor of a building
to another floor). In areas where the
weather is not affected by the change of
air pressure, this feature will be less
accurate.
