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

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.

The temperature measurement area should be protected from sunlight to avoid high results.

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.

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

Power on and wait for 30 seconds, keep nothing in front of the temperature sensor.

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.

Measurement method: Measure forehead or wrist surface

Forehead temperature and wrist surface temperature can be measured without adjusting settings.

Measurement area: the center of forehead or the wrist covered by sleeve.

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.

Body Temperature Measurement – Quick Guide V 6.1

Measurement time: 0.5 seconds. After the measurement, please leave quickly. Otherwise the

measurement will be repeated.

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.

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

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.

The temperature cannot be measured when the machine is started Treatment: wait for 30 seconds after power

on, and then measure the temperature.

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.

Temperature measurement is not sensitive Treatment: when measuring body temperature, stay at the

target measured by infrared temperature sensor for 1 second.

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.

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.
