    • 2.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.
    • 3.May I reuse the probe cover?+

      If you bought a probe cover model, in order to avoid cross contamination, we recommend user to change probe cover after each measurement. Also, check the probe cover is in good shape and the ear canal is clear without earwax.
