Precision : +/- 0.5°C at 25°C and +/- 1.5°C in the measuring range between -20 and 80°C
Response time : The temperature sensor is located on the left, above the display. In the event
of a sudden change in the temperature, it is necessary to allow the sensor enough time
to reach the ambient temperature. This duration will depend on the temperature difference
and wind force.
Holding the instrument in one's hands for a long period of time may have an impact on
measuring the temperature, all the more if the temperature is low.
Temperature actually felt (windchill factor) :
You are certainly aware that exposure to low temperatures is potentially dangerous to the
human body. But did you know that wind plays a significant part in how your body actually
feels temperatures ? With your always at your fingertips, you will instantly know
the temperature felt by your body and be aware of risks of frostbite and hypothermia.
Calculation : The windchill factor is calculated on the basis of ambient
temperature and wind speed. In the presence of wind, it gives an idea of
the body heat loss if the ambient temperature is below 37°C, and of the
body heat gain should the temperature be above 37°C.
Example : together, an ambient temperature of 0°C and a 30 km/h wind
have the same effect on you as a temperature of -13°C !
See Fig. 3
Display :
Resolution to the unit.
You can display the windchill factor by pressing the wind button for about 1 second.
The windchill factor or temperature actually felt in °C or °F is then shown in the lower part of
the display, using the symbol .
See Fig. 3
Switching off
The instrument will automatically switch off approximately 10 minutes after a button
was last actuated. You can also turn it off manually by pressing simultaneously the temperature
and wind buttons for approximately 2 seconds.
Power Supply
operates on a replaceable, type CR2032 3V door-knob cell battery.
Battery low :
When the battery provides insufficient power, the middle display of your
instrument displays the symbol , thus telling you that it is
time to replace the battery.
See Fig. 4
Battery lifetime :
More than 2 years for regular use.
