Question
The temperature sensor on my
Suunto wristop computer does not work properly. It's over 20°F greater than the actual temperature.
Answer
When you wear your wristop on your wrist, your body heat will affect the temperature sensor. The wristop readings will indicate a temperature somewhere between your body temperature and the actual temperature.
To achieve a more accurate reading, remove the wristop from your wrist and wait at least 15 minutes before reading the temperature again.
