Body Temperature Measurement – Quick Guide V 6.1
Disclaimer
The infrared temperature measuring device is the human body surface temperature
screening instrument. The test results only reflect the real-time temperature evaluation
of objects or people in a specific environment. The selling company and the manufacturer
shall not bear any responsibility for the direct or indirect loss caused by the use of the test
results.
Installation precaution
1. It is recommended to install it indoor free from wind. The cold wind might influence the
accuracy in windy outdoor. In this case, we have to increase the environment temperature
compensation, 5° C per time.
2. The temperature measurement area should be protected from sunlight to avoid high results.
3. When it is used outdoor under special circumstances, build a shed on site. The height of
the shed should be more than 2.4m (7.87ft) to ensure the stability and free from wind.
People walk slowly through it to measure thetemperature.
Temperature measurement module
Temperature sensor:
Real time infrared thermo sensor to detect temperature,
ready in 30 seconds after power on.
Distance sensor:
The distance sensor starts working when a person or
object is in 20cm (7.87” in) to it. If the temperature of person
or object detected is ≥ 35.5 ℃, the voice "Normal
temperature" is trigged; if it's lower than 35.5 ℃, or higher
than the set value with alarm, the voice "Please check
again" is trigged.
When the ambient temperature is lower than 15 ℃, if the
temperature of person or object detected is ≥ 34.5 ℃, the voice
"Normal temperature" is trigged; if it's lower than 34.5 ℃, or higher
than the set value with alarm, the voice "Please check again" is
trigged.
Special attention: the distance sensor shallnot be blocked,
otherwise it will repeat the voice broadcast.
Power Light:
The indicator light is on when the temperature measurement
module is working. When measuring the foreheadtemperature,
the measured result is the most accurate when the middle of
human eyes is right facing the temperature indicator.

Distance sensor debugging
Press D button in the main interface (display CCCC), press B button to enter the password input interface (display
1234), and press B button and C button to input the password 1321. Press D button to display FFFF, indicating the
password is correct. Press B button to enter the function setting interface (display 0200). Press B button to shift and C
button to adjust the distance value. Press D button to complete the setting (display 0000). Press A button twice to
return to the main interface.
● "0200" means the effective distance between the thermal sensor and the target is within 20cm (7.87” in).
When a Target comes close within 20cm (7.87” in), it triggers the thermal sensor to work.
● When the distance is set to 0100, the temperature result is the most accurate.
The number of 8190 or 8191, showing in the first line, is the initial value of the distance sensor, which means there is
no obstruction 130cm (51.18” in) in front of the thermal sensor. In this situation, if you block the thermal sensor with
your hand at 20cm (7.87” in) in the front of the thermal sensor, you will see 0200 at the second line (with an error of
about 1 cm (0.39” in)).
If there is no object blocking but a different number flashes in the first line, it means that the distance sensor is
interfered. In this situation, the voice of "Please check again" is repeated. We have to eliminate the interference
Metal detection off setting

to detect small size metals, and 50 means not detect small size metals.
● D001 of the first line is the alarm time setting, and 1.0 of the second line means the alarm time is 1 second.
Instruction of temperature measurement
1. Power on and wait for 30 seconds, keep nothing in front of the temperature sensor.
2. Normal ambient temperature is 0°C - 35°C. When using it at - 10°C, you have to decrease the
environment temperature compensation, 5°C per time, until the result difference between it and the
forehead thermometer is less than
± 0.3°C.
3. Measurement method: Measure forehead or wrist surface
4. Forehead temperature and wrist surface temperature can be measured without adjusting settings.
5. Measurement area: the center of forehead or the wrist covered by sleeve.
6. Standard measurement distance: 1cm-10cm (0.39”-3.93” in). When measuring at a distance of 10-30cm
(3.93”- 11.81” in), it is necessary to adjust the environment temperature compensation, 5°C per time,
until the result difference between it and the forehead thermometer is less than
± 0.3°C.

7. Measurement time: 0.5 seconds. After the measurement, please leave quickly. Otherwise the
measurement will be repeated.
8. During the temperature measurement, influenced by the measurement speed, the temperature might
suddenly fluctuate up and down. In this case, please measure the body temperature 3-5 times
continuously, and take the average value as the final measurement result.
9. The instrument automatically detects the temperature of the object in 20cm (7.87” in) in front of it. After
measuring the temperature, we have to move our hand or forehead away. If we keep close to the sensor
for long time, it will stop working asa protection.
Common trouble shooting
1. Metal detection does not count Processing method: press the power key to switch from the
temperature measurement interface to the metal detection and counting display interface.
2. The temperature cannot be measured when the machine is started Treatment: wait for 30 seconds after power
on, and then measure the temperature.
3. Low temperature measurement Processing method: check whether the value set in 1319 interface is 25, if not,
change to 25. And then use the hand-held electronic infrared Thermometer comparison test, if the measured
values are consistent, it means that the equipment is working normally. If there is a deviation greater than 0.5 ℃,
please refer to Debugging is described on the second page.
4. Temperature measurement is not sensitive Treatment: when measuring body temperature, stay at the
target measured by infrared temperature sensor for 1 second.
5. Metal detection sensitivity is too high Processing method: the setting item L008 in function setting password 1111
is changed from 1 to 50, excluding small metal parts.
6. Network connection failure Processing method: check whether the IP address of the computer is completely
consistent with the instructions. If not, please set the IP address according to the instructions, if it is
consistent, please refer to the video and operate again.
