Temperature Sensor
The sensor will indicate the temperature with the following allowance: +/- 2 degC max (typical +/-1 degC)
Most of the electronic components bear a commercial grade with a behaviour guaranteed between 0-40 degrees Celsius. Tests on the AlpinerX have shown that the watch still works well at -10°.
If the watch is exposed below -10 and over +50 degrees, the watch won’t break but the accuracy of the measurements is not guaranteed.
UV Sensor
The sensor will indicate the index with the following allowance: +/-1 UV index
Altimeter & Barometer
The ATM pressure will change depending on weather conditions. The altitude is calculated thanks to this pressure. A change in altitude equals a change in the ATM pressure measurement.
