1. Safety Instructions

To ensure proper use of this product, please read the instructions carefully before using.

• To ensure measurement accuracy, please use the product in an operating environment of 0°C~50°C, <85% RH (non-condensing).
• 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 this product in flammable, explosive, steamy, wet or corrosive environments.
• Please stop using the product if it is damaged or modified to avoid inaccurate measurement results.
• Please use the correct emissivity to obtain accurate temperature readouts.
• To ensure accuracy of the product, please warm it up for 10 minutes before measuring if it has not been used for a long time.
• When being charged, the internal temperature of the product rises, which will lead to inaccurate temperature measurement. So, it is not recommended to take measurements during or right after charging the product.
• The inherent temperature drift of the sensor will occasionally cause inaccurate measurement. In this case, press the down button under the temperature measurement interface to bring out "Calibrating" and automatically calibrate the temperature.
