6. Operating Instructions
6.1 Taking a Temperature Reading
- Ensure the thermometer has power (display is active).
- Place the metal probe tip into the environment or substance you wish to measure. For air temperature, ensure the probe is suspended and not touching any surfaces for an accurate reading.
- Allow a few moments for the temperature to stabilize on the LCD. The thermometer provides fast readings, but stabilization time may vary depending on the temperature difference.
- Read the temperature directly from the LCD display. The unit typically displays temperature in Celsius (°C).

7.2 Storage
Store the thermometer in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Coil the probe cable neatly to prevent tangling or damage.
