1. Product Introduction and Classification
This product can measure body temperature by collecting the infrared thermal radiation from the human forehead. It is simple and convenient to operate, and the measurement is fast and accurate.
Scope of application: the body temperature of the subject is shown by measuring forehead thermal radiation.
2. Basic Working Principles
Any object will emit infrared thermal radiation energy, and its surface temperature directly determines the radiation energy size and wavelength. Based on this principle, this product adopts a high-precision infrared sensor specifically used for detecting the infrared radiation energy emitted by the the human body with the wavelength of 5-14um, and accurately measures the body temperature through accurate calculation and various compensations and corrections.

The product provides five functional Settings, including temperature unit, alarm switch, temperature alarm point, temperature deviation, and measurement mode. The measurement mode setting is set by the mode switch key, and other Settings are set in the Settings menu.
The comparison table of setting menu is as follows:
|Menu||Function||"-" key||"+" key||Initial value||Remark|
|F2||Temperature alarm point||By 0.1ºC||Increased by 0.1ºC||38ºC|
|F3||Temperature deviation||Down 0.1ºC||Up to 0.1ºC||0.0||The scope of ±3ºC|
Measurement mode setting:
When the machine is on, press the "set" button to switch the measurement mode to body temperature and surface temperature.
Temperature unit set - F1
Press and hold the "set" key for 2 seconds, the screen will display F1, and the Celsius icon will flicker. Press the "-" key to switch units of "Fahrenheit", and press the "+" key to switch Celsius.
Setting Temperature Alarm Point - F2
Press "set" key for 2 seconds to display F1 on the screen, press "set" key to enter F2 once, then press "+" key to increase the temperature by 0.1ºC, press "-" key to reduce the temperature by 0.1ºC. Note: The default value for alarm is 38ºC (100.4ºF).
Temperature Offset Setting - F3
Press and hold the "set" key for 2 seconds to display F1 on the screen, press and hold the "set" key to enter F3 for 2 times, then press and hold the "+" key to increase the offset value by 0.1ºC, and press and hold the "-" key to reduce the offset value by 0.1ºC.
Cue Switch - F4
Press and hold the "set" key for 2 seconds, the screen will show F1, press and hold the "set" key for 3 times to enter F4, then press and hold the "+" key to start the buzzer, press and hold the "-" key to close the buzzer.
7. Measurement Method
Make sure the screen is in temperature mode.
Aim the probe of the thermometer at the middle of the forehead and maintain a vertical distance of about 3cm ~ 5cm. Press the "measure" button, about 1 second later the measured temperature will be displayed. If the measured value exceeds the temperature alarm point (default 38ºC), a "Beep" alarm will sound.
When a change of ambient temperature has a great impact on forehead temperature, please measure the earlobe.
