HYSTERESIS
To compensate for fluct uation of the measured data, which may c ause
the weather alarm to sound co nstantly if the measured reading is close
to your set level, a hy steresis function has been i mplemented for e ach
weather alarm. F or example, if the high te mperature alarm is set to
+77°F and the current value moves to +77°F, the ala rm will be activated
(if it has been enabled). Now when the temperat ure drops to +76.8°F or
below and thereaft er again increases to bey ond +77°F, t he data will be
blinking, but no a larm will be activate d. It has to drop to below +75. 2°F
(with a pre-set hys teresis of 1.8°F) so that t he alarm can be produced
again. Hysteres is values for the various w eather data types are g iven in
the following tab le:
Weather data Hysteresis
Temperature 1. 8°F
Humidity 3 % RH
Wind speed 3.1 mph
Note:
The temperature or humi dity data will keep o n flashing even afte r a key
has been pressed to st op the alarm or buzzer has be en switched off, to

WEATHER FORECAST AND WEATHER TEN DENCY
WEATHER FORECASTING ICONS:
Weather forecasting i cons are displayed in a ny of the followin g
combinations at the right bottom part o f LCD:
For every sudde n or significant change in the air pressure, the weather
icons will updat e accordingly to represent th e change in weather.
(Every time a new average pres sure value has been obta ined (once per
minute), this valu e is compared with an interna l reference value. If t he
difference betw een these values is bigger than the s elected weather
tendency sensitivi ty, the weather-icon changes , either for worse or for
better. In this case, the current pressure v alue becomes the new
weather tendency reference.)
If the icons do not change, either the air pressure ha s not changed or
the change has been too small for the Weather Center t o register. So
you may adjust th e "sensitivity" of the pressure c hange checking in t he
setting mode –see WEA THER TENDENCY SENSITIVITY VALUE
SETTING above.
However, if the icon dis played is a sun or raining c loud, there w ill be no
change of icon if t he weather gets any better (wi th sunny icon) or worse
(with rainy icon) sinc e the icons are already at their extremes.
The icons display ed forecasts the weather in terms of getting better o r
worse and not nec essarily sunny or rainy as e ach icon indicates. Fo r
example, if the cu rrent weather is cloudy and t he rainy icon is display ed,
it does not mean t hat the product is faulty becaus e it is not raining. It
simply means that th e air pressure has dropped an d the weather is
expected to get w orse but not nec essarily rainy.
Note:
After setting up, readings for weat her forecasts should be disregarde d
for the next 48- 60 hours. This will allow sufficient time for the W eather
station to collect air press ure data at a constant altitude and therefore
result in a more accurate forecast.
Common to weather fore casting, absolute acc uracy cannot be
guaranteed. The wea ther forecasting feat ure is estimated to have an
accuracy level of about 75% due to the varyi ng areas the Weather
Center has been desig ned for use. In areas that experience sudden
changes in wea ther (for example from sunny to rain), the Weathe r
