  2. Before taking the temperature, please make sure to select the temperature measurement modeStep 1: under the shutdown state, press the measurement key once to turn on the machine and light up the display screen to enter the state to be testedStep 2: place the measuring probe close to the forehead. Make sure that the probe plane is parallel to the forehead plane, and the forehead temperature is measured 1 ~ 3cm away from the forehead. Press the temperature measurement key and hear a drop. The LCD displays the current test value.

(when the screen is on, press the measurement key once to measure. If the measurement result is normal, please refer to the data in the following table.)

The maximum allowable error of human clinical diagnostic test accuracy is regulated by the following formula:

T1 and T2 are the temperature readings of the tested thermometer twice, and Tref is the fixed reference temperature.

Structural Function

  1. The main structureInfrared thermometer consists of abs plastic shell, temperature probe, buttons, LCD display and battery.
  2. Material temperature / body temperature testClick the temperature measurement key, the machine will automatically turn on the power and start the test automatically, and the temperature of the measured object will be displayed on the screen. When the temperature is lower than 37.4 ℃ and higher than 32.0 ℃, the screen will use green backlight to light the LCD, and at the same time “drop” sound will remind.
    1. Short press the temperature key to test the temperature
    2. Click the temperature measurement key once, and then press the key again to switch the OC / OF, and then turn on the machine again to memorize the temperature mode
  3. High / Low temperature alarm

  5. Temperature measurement mode switchingIn the power on state, click and long press for 2 seconds to switch between body mode and object mode. The default body mode is when the power is turned on.
  6. Restore factory settingsIn power on mode, press and hold test key for 10s.

Precautions for Use

Infrared thermometer is a precision electronic product, please use it carefully

  1. The infrared temperature gun must be used under the working conditions required by this manual.
  2. Do not remove the thermometer from the measurement area before the “drip” sound ends
  3. Always place the thermometer in the same position, because different positions may cause deviations in body temperature.
  4. According to the difference of human skin color and thickness, the measured temperature will be different.
  5. When measuring the temperature of the forehead, make sure that the forehead is clean, and there must be no sweat, hair or hat blocking, otherwise the measured temperature will be low.
  6. Do not drop the ground or twist the body
  7. It is not necessary to be close to or stacked with other equipment. If it must be close to or stacked, it can only be stacked up to two layers at best.
  8. The temperature sensor can be wiped and disinfected with an alcohol cloth in front of the display. Never put it in water or boil it in hot water for disinfection.

Note: For the following situations, it is recommended to measure three times, and take the highest reading as the final result.

  1. For children under the age of three with impaired immune system and people who have a huge impact on fever.
  2. When the user first learns how to use it for measurement, the measurement is repeated many times until he and she are familiar with the device and can read stable data.
  3. If the measurement result is abnormally low.In short, the temperature readings measured at different measurement points should not be compared, because the measured values will vary depending on the measurement time. During a day, the person’s body temperature is highest in the evening and lowest in the morning before waking up in the morning.
