FAQs Brief Specs Question While I'm using the thermal imaging function, why is there a clicking sound with a frozen screen, once every few dozens of seconds? Features Answer To ensure measurement accuracy, the TC002 performs periodic internal temperature calibration every few dozen seconds. This process is controlled by a micro-motor and causes a clicking sound and a brief screen freeze. To disable the internal calibration function, go to the TC002 app's Personal Information section and turn off Auto Shutter. Functions Question What's In The Box? What external factors will affect the infrared temperature measurement? Answer The factors are as follows:
Comparison a) Emissivity of the target object surface. b) Ambient temperature: the object will reflect the infrared rays emitted by surrounding objects, which affects the temperature measurement of the object itself. c) Atmospheric temperature: the atmosphere also emits infrared rays. d) Atmospheric transmittance: the infrared rays emitted by the object are attenuated in the atmosphere. e) Distance: the longer the distance, the greater the attenuation of the infrared rays emitted by the object in the atmosphere.
