How to use non-contact infrared thermometer
1. The first step is to check whether the non-contact infrared thermometer used has power. You need to install the battery first, and then open the test key.
2. Align the infrared detector part to the center of the forehead-above the eyebrow and keep it vertical. The measurement area should not be covered by hair. If there is sweat, dry it first and then measure it. It is recommended to keep the distance from the forehead at 3-5cm about.

3. The thermometer will display the temperature on the screen, record the value, and generally test multiple sets of values, take the highest value as a reference, and then the temperature measurement ends.
