4.3.7.1 ABSOLUTE OR RELATIVE BAROMETRIC PRESSURE MODE
In normal mode, press [ BARO ] key to switch between ABSOLUTE and RELATIVE barometric
pressure.

1. Temperature index indicator
2. Outdoor sensor low battery indicator
3. Outdoor sensor signal indicator to show the signal
receiving strength
4. Outdoor temperature reading
5. Outdoor temperature trend
6. Outdoor humidity reading
7. Outdoor humidity trend
4.3.9 OUTDOOR TEMPERATURE INDEX
In normal mode, press [
/ NDX ] key to switch between
Feels Like, Heat Index, Wind Chill, and Dew Point of
outdoor.
4.3.9.1 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
temperature as Feels Like Temperature.
4.3.9.2 HEAT INDEX
The heat index which is determined by the wireless 7-in-1 sensor's temperature & humidity data
when the temperature is between 26°C (79°F) and 50°C (120°F).
Heat Index range Warning Explanation
27°C to 32°C (80°F to 90°F) Caution Possibility of heat exhaustion
33°C to 40°C (91°F to 105°F) Extreme Caution Possibility of heat dehydration
41°C to 54°C (106°F to 129°F) Danger Heat exhaustion likely
Extreme Danger Strong risk of dehydration / sun stroke
4.3.9.3 WIND CHILL
A combination of the wireless 7-in-1 sensor's temperature and wind speed data determines the
current wind chill factor. Wind chill number are always lower than the air temperature for wind
values where the formula applied is valid (i.e. due to limitation of formula, actual air temperature
higher than 10°C with wind speed below 9km/h may result in erroneous wind chill reading).
