Question: why thermometer readout inaccurate?
1)The accuracy is 0.2 degrees centigrade(0.4 degree Fahrenheit)
2)Measuring distance is 1-5cm(0.4-2 inch)(distance from forehead to thermometer), this is very important for precise measurement, also pls keep forehead remain still, pls don't shake.
3)Pls choose right mode, wrong mode will readout inaccurate. Body mode for forehead, Object mode for water, milk, room temperature etc.
4)The infrared thermometer mesure area is only one point, the application is forehead, so pls keep forehead not cover by hair or glasses.
5)The temperature of forehead and underarm is different. It's scientific, so the readout is different with mercury thermometer.
6)If battery power is low, it will readout inaccurate.
7)From out doors to indoors with big difference of temperature, please wait for 20 minutes after the human body fit environment temperature.
