2. Turn the dial switch to the temperature gear, and press the SELECT button to switch between °F/°C.
3. Make the temperature probe touch the surface of the object to be measured, and the measured value can be read after the reading is stable.
Note: The ambient temperature of the instrument should not exceed the range of 18°C-28°C, otherwise it will cause measurement errors.
