FEELS LIKE / WIND CHILL / HEAT INDEX / DEW-POINT
Weather Index
At the WEATHER INDEX section, you can press [ INDEX ] key to view the
weather index in this sequence: FEELS LIKE > WIND CHILL > HEAT INDEX
> DEW POINT.
Feels Like
Feels Like Temperature shows what the outdoor temperature will feel
like. It’s a collective mixture of Wind Chill factor (18°C or below) and
the Heat Index (26°C or above). For temperatures in the region between
18.1°C to 25.9°C where both wind and humidity are less significant in
affecting the temperature, the device will show the actual outdoor meas-
ured temperature as Feels Like Temperature.

Reading dewpoint (indoor)
Press INDEX button several times until INDOOR DEWPOINT is displayed.
NOTE!
The dew point is the temperature below which the water vapor in air at
constant barometric pressure condenses into liquid water at the same
rate at which it evaporates. The condensed water is called dew when it
forms on a solid surface.
The dewpoint temperature is calculated from the temperature and humid-
ity measured at the main unit.
