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.

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.
