What is Wet-Bulb Globe Temperature?
Wet-Bulb Globe Temperature (WBGT) is a summer heat index that indicates
the level of severity of heat. In addition to the air temperature, the calculations
of this heat index take into account humidity (which affects sweating) and
forms of radiant heat such as solar radiation and reflected heat. The index is
calculated from dry-bulb temperature (ambient temperature), wet-bulb
temperature (related to humidity) and black globe temperature (related to
radiant heat). The result is expressed as a temperature in Celsius (℃).
Outside (with solar radiation):
0.7 x wet-bulb temperature + 0.2 x black globe temperature + 0.1 x dry-bulb temperature
Inside (no solar radiation):
0.7 x wet-bulb temperature + 0.3 x black globe temperature
This device measures the dry-bulb temperature with a thermistor and calculates the
wet-bulb temperature from the dry-bulb temperature and a relative humidity value
measured with a humidity sensor. The black globe temperature is calculated by
converting the temperature measured with a 33mm-wide black globe to the
equivalent value for a standard 150mm-wide black globe. This device also uses the
difference between the dry-bulb temperature (ambient temperature) and black globe
temperature to predict whether the user is outside (where there is solar radiation) or
inside (where there is no solar radiation). The WBGT is then displayed according to
this automatic judgment.

Inserting the Battery
1.Use the provided screwdriver or a small
commercially available small screwdriver
to unscrew the screws in the
counter-clockwise direction and remove
them.
2.Insert the battery (CR2032) with the “ ”
side facing upwards in the direction of the
arrow.
When the battery is inserted, a “beep”
sound is heard and the power turns on.
3.Align the tab on the battery cover with the
indentation on the unit, replace the
battery cover to its original position and
tighten the screws in the clockwise
direction.
See “Attaching to a Tripod” (p.13) when
attaching this device to a tripod for use.
*Be sure to remove the batteries when storing this device for a prolonged period
(more than 3months).
