1. Check whether the measurement distance is adequate. The

recommended measurement distance is 20–30cm for single

point series and 50–70cm for matrix series.

2. Check whether the people get close to occupy the human shape

on the screen and aim the forehead center at the red circle.

3. Check whether the forehead is covered by fringes, hats,

sunglasses, or other objects when the forehead temperature

needs to be taken. If so, remove such objects 0.5 to 1 minute

before the temperature can be taken.

4. Check whether the body surface temperature is too low. If a

person comes from an outdoor low-temperature environment to

the measurement area, the person needs to stay in this area for

5 min before the temperature is taken.

1. The device requires preheating after power-on. It enters the

optimal temperature measurement state 15 minutes later.

2. Check whether the people get close to occupy the human shape on

the screen and aim the forehead center at the red circle.

3. Check whether the forehead is covered by fringes, hats,

sunglasses, or other objects when the forehead temperature

needs to be taken. If so, remove such objects 0.5 to 1 minute

before the temperature can be taken.

4. Check whether the device is used in an environment with low

temperature, high temperature, or strong wind. If yes, deploy

the device in an indoor windless environment with the

temperature of 10°C to 45°C.
