 Basic Working Principle

Any object will release infrared radiation energy, and the surface temperature directly determines the size and wavelength of the radiation energy. Based on this principle, this product is designed to apply the German high-precision infrared sensor to detect the infrared radiation energy with the wavelength of 5-141.im released by the human body, and accurately measure the human body temperature through the accurate operation and a variety of compensation correction.

Set operations

This product provides the function settings including the temperature unit, warning tone switch, temperature alarm point, temperature offset, and measuring mode, and so on. The measuring mode is set by the MODE button, and the other settings are set in the Set Menu. The table of Set Menu is as follows:

from -3 t to i 3 t
F4| Warning Tone Switch| Off| On| On|

Measuring Mode Setting

In the Power-On state, the screen displays the current measuring mode (Fig. 8.1), press the MODE button to select the desired measuring mode (Fig. 8.2), and the setting takes effect immediately.
Temperature Unit Setting—-F1
Press the “MODE” button for 2 secs, the screen displays Fl (Fig. 8.3), press the “-” button, select the temperature unit of Fahrenheit (Fig.8.4) , press the “+” button, select the temperature unit of Celsius (Fig.8.5).

Temperature Alarm Point Setting—-F2
Press the “MODE” button for 2 secs, the screen displays Fl, press the “MODE” button once to enter F2, then press the “+” button to increase the temperature value by 0.1°C (0. 1°F ) , and press the”-“button to decrease the temperature value by 0. 1°C (0. 1T) . Note : The alarm default value is 38°C (100. 4°F ) . Temperature Offset Setting—-F3
Press the “MODE” button for 2 secs, the screen displays F 1, press the “MODE” button twice to enter F3, then press the “+” button to increase the deviation value by 0.1°C (0. 1°F ), and press the”-” button to decrease the deviation value by 0. 1°C (0. 1 T ). When the season or environment changes, the infrared thermometer shall be checked and adjusted.
Warning Tone ON/OFF Setting—-F4
Press the “MODE” button for 2 secs, the screen displays Fl, press the “MODE” button three times to enter F4, and press the “+” button to turn on (ON symbol appears on the screen) or turn off the beep (OFF symbol appears on the screen). After entering the Set Menu operation, if you want to modify a setting, you can continuously press the Menu key to select. Save the settings in order after the completion of new settings, if shutdown and exit at midway, the new settings will not be saved. After entering the Set Menu, if pressing the measuring key is invalid, the measurement will not be implemented by the thermometer.

Tips:
1. Body temperature mode is suitable for the measurement of human body temperature which is obtained from the dynamic compensation between the ambient temperature and forehead surface temperature.
2. According to the ambient temperature, measuring distance, specific individual skin differences and other factors, the temperature offset value can be used to amend the measured value through the different value between target measured value and true value, with the correction range of from -3.0 °C to +3.0 °C and the factory setting of 0.0 °C. For example, if the body temperature measured by the thermometer is 36.2 °C, and the actual temperature of measured target is 37.0 °C, then enter into F3 to increase the deviation by 0.8°C, after completing, the same result as the actual body temperature is obtained.

Measuring Method

Make sure that the measuring mode above on the screen is the body temperature mode. Align the thermometer probe to the forehead in the middle and keep it vertical with a distance of about 3-5 cm (Fig. 9.1). Press the measuring key, after 1 second with the sound of “beep”, the measured value (Fig. 9.2) is displayed and the measurement is completed. If the measured value exceeds the temperature warning point (the default value is 38°C), the warning tone of five “beeps” is triggered.

If the environmental temperature changes largely and affects the forehead temperature, please measure it through aligning on the back of earlobe (Fig.9.3).
Tips
Before and after use, please keep the sensor and probe inside clean. Please put the thermometer in a stable environment. When the ambient temperature changes greatly (from indoors to outdoors), please use it after keeping it for about 30 minutes. Do not begin measuring the body temperature immediately after measuring extremely high or low temperature. Please hold it for 30 minutes and then use it. When the measured object comes from the place where the temperature is greatly different from the test ambient temperature, keep the thermometer stay in the test environment for at least five minutes or more. Try not to use it after blowing, shower, sweating, smearing cosmetics, etc. on the forehead. Don’t use it within 30 minutes after exercise, bathing or eating.

after sun, hot bath, sweating, hot air blowing, and smearing cosmetics, etc. on the forehead.
2.Check the temperature offset setting (>0)and the factory setting is 0.0.
3.Check the operation environment. If the instrument has just measured the ultra-high temperature environmental, then directly measure the low- temperature object, thus, the test dev action will occur and it should be used in a relatively stable environment after placing it for about 10 minutes to obtain a new testing heat balance.
“LO” displays on the screen| 1.Check the measured object. Try not to use it after a cold, cold bath, cold air blowing, and smearing cosmetics, etc. on the forehead.
2.Check the temperature offset setting (<0) and the factory setting is 0.0.

The formula for the recommended isolation distance is as follows:
d=1. 2 Xli.
d=1. 2 X Ji 80MHz to 800MHz
d=1. 2 X Ji 80MHz to 2.5GHz
Wherein, P is the rated output power of transmitter in watts; d is the recommended distance in meters. The field strength of RF transmitter obtained from measuring a by the electromagnetic field must be less than the conformity grade within each frequency range b.
Interference may occur near the device marked the following symbol: i
Note 1: In 80MHz-800 MHz, apply the formula at a higher frequency range.
Note 2: The above guidelines are not suitable for all situations, since the unknown structures, objects, and crowds can absorb and reflect the electromagnetic waves, which will affect the electromagnetic propagation.
The field strength of the base stations of radio mobile phone (cellular box wireless)and the terrestrial mobile radio receivers, antenna receiving devices, FM and AM radios as well as TV broadcasts can not be accurately estimated by using purely theoretical methods. In order to evaluate the electromagnetic environment generated by the solitary radio frequency transmitter, the methods of electromagnetic field measurement should be considered. If the field strength of equipment used exceeds the required RF level, it is necessary to observe whether the device will work properly once abnormal conditions have been detected, measures must be taken such as repositioning the device or moving it to other conditions.
b In the frequency range of 150k -80MHz, the field strength should be less than 3V / m.
