Notice for Use

Please use the correct emissivity to obtain accurate temperature readouts.To ensure accuracy of the product, please warm it up for 20 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 product has a self-calibration function. If the reading jumps quickly, please read the temperature after it gets steady.
