  • 3.Why is my measurement too low or high?+

    You may check by following items:
     
    • Ear Canal:  
      Earwax might block the infrared measure accuracy.
    • Probe Cover:  
      The most popular situation is the probe stuck with earwax that blocked infrared transmission and lower the measurement. If you bought a probe cover model, we recommend user to change probe cover each time to avoid cross contamination.
    • Note:  
      If you bought a probe cover model, the probe cover may break and affect the accuracy after using for several times or receive external hit. We recommend user to check probe cover's integrity before every measurement. If the probe cover is broken, please change a new one.
    • Lens:
       If you bought a probe cover model, the most common situation is user measure without installing probe cover. The probe lens is stuck with earwax and lower the measurement. If the lens is dirty, please follow the manual's instruction to clean lens with cotton swab.
    • Note:  
      User hit the thermometer carelessly might cause the probe lens damage. Please return full package to retailer for service if there is damage.

    1. Before using the cotton swap with 70% alcohol to wipe the lens, slightly flip the cotton swab to cut down the spare alcohol.
    2. If there is no 70% alcohol, use alcohol prep pad to soak the cotton swab.

      Important:  Do not use sharp pointed object to wipe the lens.
  • 16.Does summer and winter ambient temperature affect the measurement?+

    RADIANT INNOVATION ear thermometer compares ambient temperature and makes compensation. The measurement between 10°C~40°C (50°F~104°F) is the same, but the human body changes a little in different season and different environment. For example, the body temperature becomes hotter after exercise and hot shower.
  • 17.Is the ear temperature more precise than oral temperature?+

    The ear canal of both ears is not totally the same. Some people can get same temperature but most people get 0.5 ~ 1.0°C different temperatures. RADIANT INNOVATION consider the 0.4°C inaccuracy is due to the sensor did not completely receive the ear's infrared. Basically, when the self diagnosis function is normal, the different temperature is affected by the measuring probe's location. It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the highest temperature.
  • 18.Why do I have to wait for 6 seconds during constantly measurement?+

    Wait 6 seconds is to reduce the thermal shock effect result from probe of thermometer contact with ear channel, and hence reduce the chance to affect the accuracy.
  • 19.Can I measure without probe cover?+

    If you bought a probe cover model, we recommend user to install probe cover before measurement base on hygienic principal. A thermometer measurement without probe cover might cause 1°C inaccuracy.
  • 20.The measurement only takes 1 second?+

    Yes, it's real. The infrared thermometer sensor could easily receive the infrared ray sent out from human body. RADIANT INNOVATION ear thermometer breaks the old measure style about how long and which part. Just put ear thermometer into the ear canal and press SCAN button for 1 second to get temperature. From now on, parents could easily get your excited baby's body temperature without breaking the mercurial thermometer.
  • 21.Is the thermometer waterproof?+
