1.Product introduction
2.Product components
This product measures the body by collecting infrared
thermal radiation from the forehead temperature. The
operation is simple and hygienic, and the measurement is
accurate. The user only needs to align the probe, then
temperature can be measured by pressing the
measurement button.
Widely used in schools, customs, hospitals, homes.
Note: According to the difference of skin and the parts of
the body to be tested, the measured temperature will be
different. This is normal, because the more exposed the
body parts, the greater the influence of the ambient
temperature.
This product is composed of infrared sensor,
microprocessor, memory, Battery, electro-acoustic
components, display screen and casing.

sweating, and applying cosmetics, the
measurement cannot be guaranteed.
2.Pease check the temperature offset value. The
factory setting is 0.0.
3.Please check the operating environment.
Environmental changes have a great impact on
the measurement. If the ambient temperature
changes greatly, or the instrument has just
measured ultra-high temperature objects and
directly converted to low-temperature objects,
the test difference will occur. It should be placed
in a stable environment and left for about 10
minutes before use.
4.Please check the measurement distance
(3-5cm).
1.Reinstall the battery.
