Section 6 FAQ Q While I'm using the thermal imaging function, why is there a clicking sound with a frozen screen, once every few dozens of seconds? A As the temperature of the infrared imaging camera changes slightly during use, to ensure measurement accuracy, a periodic internal temperature calibration is needed every a few dozens of seconds. The micro-motor controlled activation or deactivation of such internal calibration makes a clicking sound during which the screen freezes for about one second. To turn off the internal calibration function, please open the TC003 app, go to Personal Information , and turn off Auto shutter.
Q Can the TC003 detect objects underwater, through glass or a wall? A No. Infrared detectors mainly detects 8 to 14 μm long-wave infrared areas, and can only be used to measure surface temperature. Q Why is there a lower temperature reading when the device gets far from the object and a higher reading when the device gets closer to the object? A Infrared radiation attenuates when passing through the atmosphere. The longer the distance, the greater the attenuation. Thus, the accuracy of temperature measurement at a distance will decrease. To ensure accuracy of measurement, go to Personal Information > Temperature Correction > Distance to Spot , and input the actual distance (max:
5 meters) to get the corrected temperature. Q Is the TC003 compatible with iOS devices? A No, the TC003 is ONLY compatible with Android devices and Windows computers. Q Why is the measured temperature not very precise? A The temperature resolution of TC003 is ±2%. And the TC003 provides a normal temperature range of -4 to 302°F (-20 to 150єC), and a high temperature range of 302° to 1022°F (150 to EN I 16
