• When changing to a new environment, please turn on the product and leave it for 10 to 15 minutes before measuring.
• The ambient temperature for measuring must be stable. Do not measure in places with large airflow such as fans and air outlets.
• When the measured object comes from a place with a large temperature difference from the measurement environment, keep it in the measurement environment for 10 to 30 minutes before measuring.
• The product tests the surface temperature of the object. If temperature compensation is needed, please adjust in the Settings menu.
• The product has a self-calibration function. If the reading jumps quickly, please read the temperature after it gets steady.
• After measuring extremely high or low temperature objects, please leave the product for 10 minutes before next use.
• Do not use the product in places with strong sunlight or electromagnetic interference.
• Please do not use the product in flammable, explosive, steamy, wet or corrosive environments.
