HISTORY DATA (ALL RECORDS IN THE PAST 24 HOURS)
The main unit will record past 24 hours weather data automatically that included past indoor and outdoor
temperature & humidity, baro, wind chill, wind speed and rainfall records.
1. Press the [ HISTORY ] key to check past 1 hour history records.
2. Press [ HISTORY ] key repeatedly to show past 2, 3, 4 , 5.......24 history weather records.
MAX/MIN MEMORY FUNCTION
1. Press the MAX/MIN key to check the maximum/minimum records. The checking orders will be: Outdoor
max temperature
Outdoor min temperature Outdoor max humidity Outdoor min humidity
Indoor max temperature Indoor min temperature Indoor Max humidity Indoor min
humidity
Outdoor max wind chill Outdoor min wind chill Outdoor max heat index Outdoor
min heat index
max dew point min dew point Max pressure Min pressure Max
average
Max gust Max rainfall.
2. Press and hold the [ MAX/MIN ] key for 2 seconds to reset the maximum and minimum records.
Note:
When maximum or minimum reading is displayed, the corresponding timestamp will be shown.
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
actual outdoor measured temperature as Feels Like Temperature.
HEAT INDEX
The heat index, which is determined by the wireless 5-IN-1 sensor’s temperature & humidity data, when the
outdoor temperature is between 27°C (80°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
≥55°C (≥130°F) Extreme Danger Strong risk of dehydration / sun stroke
WIND CHILL
A combination of the wireless 5-IN-1 sensor’s temperature and wind speed data determines the current wind
chill factor.
DEW POINT
- 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 dew point temperature is determined by the temperature & humidity data from wireless 5-IN-1 sensor.
