      John CalderonAug 13, 2025
      If your eZthings Thermometer displays 'LO' or 'HI' on the LCD, it could be due to environmental factors affecting the measurement. Things like a breeze, water, sweat, or cosmetics on the forehead might interfere. Also, ensure the thermometer has been in a stable environment for at least 10 minutes to reach heat balance before taking a measurement. Finally, make sure you're holding the thermometer at the correct distance, which is 5cm to 8cm from the forehead.
