When the letters “L” and a flashing “°C” or “°F” show on the display, the thermometer is ready for use.
If the ambient temperature is below 32 °C or 89.6 °F, a “L” will appear on the LCD. If it is more than 43.9 °C or 111.0 °F, then “H” will appear on the LCD.
During the measurement process, the current temperature is displayed continuously and the “°C” or “°F” symbol flashes. The measurement is completed when a beep sounds 5 times and the “°C“ or “°F” symbol stops flashing.
The measured temperature appears on the LCD.
When the measurement is completed, please switch the thermometer off by pressing the « ON / OFF » button.
