hrs of pressure data. (View section 18: Trend Chart).
The forecast icon will always appear as “Partly Cloudy” upon powering up the
home monitor. The first several hours of forecast data may be inaccurate,
because the home monitor needs to collect barometric pressure
information. Over time the forecast icon’s accuracy will improve. (View
section 19: Weather Forecasting)
The “most accurate” professional weather forecasting system is only 70.2%
accurate. Forecasting is a very complex science involving very powerful
computer models, satellite imagery and radar. Scientific forecasts consider
barometric pressure, wind direction, dew point, etc. The HWS forecast only
evaluates the barometric pressure change over a certain period of time. It is
very much like using a traditional dial barometer for predicting changes in
the weather.
The home monitor LCD display was designed with an optimum viewing
angle from a desk position. This angle is approximately 45°.
The LCD screen works from other directions, but it is best to consider the
Optimum Viewing Angle (Section 9).
The Home Weather station requires constant battery power to accurately
scan outdoor weather readings. The wind speed sensor and the 60 meters
transmission is the main cause of power consumption. In normal
temperature ranges (50°F to 80°F, 10°C to 25°C), you can expect that the 4 x
AA batteries in the transmitter will last approximately 7 weeks (even lithium
batteries).
In colder temperatures, battery life is much less – note that the use of lithium
batteries allow the chemical reaction that is creating power to occur in
colder temperatures (-40°F / -40°C) compared to alkaline batteries, which fail
at approximately 14°F (-10°C), but it does not necessarily mean that the
battery’s charge will last longer.
Consider the amount of times you must recharge your cell phone or digital
camera. All of these items, including the HWS, use a lot of power to perform
perfectly. For power saving consider,
Power Adaptor:
a special transmitter adaptor is available to supply power to
the transmitter rather than using batteries. It is a perfect solution for your
HWS during extremely cold temperatures in the winter months when
batteries may cause problems. Please call 1-800-387-8520 for ordering
information.
