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
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 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
27°C to 32°C (80°F to 90°F)
33°C to 40°C (91°F to 105°F)
41°C to 54°C (106°F to 129°F)
≥55°C (≥130°F)
WIND CHILL
A combination of the wireless 5-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).
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.
HISTORY DATA (ALL RECORDS IN THE PAST 24 HOURS )
The Display main unit automatically record and display data of past 24 hours on the hour.
To check all the history data in the past 24 hours, press the [ HISTORY ] button.
E.g. Current time 7:25 am, Mach 28
Press [ HISTORY ] button repeatedly to view past readings at 7:00am, 6:00am, 5:00am, ..., 5:00am (Mar 27),
6:00am (Mar 27), 7:00am (Mar 27)
The LCD will display the past indoor and outdoor temperature & humidity, value of air pressure, wind chill, wind
speed, rainfall and their time and date.
MAXIMUM / MINIMUM MEMORY FUNCTION
1. Press [ MAX/MIN ] button to check the maximum/minimum records. The checking orders will be: Outdoor

2. Press and hold [ MAX/MIN ] button for 2 seconds to reset the maximum and minimum records.
Note:
When maximum or minimum reading is displayed, the corresponding timestamp will be shown.
