clicking sound during which the screen freezes for about one second. To
turn off the internal calibration function, please open the TC002 app, go to

Q: What external factors will affect the infrared temperature measurement?
A: The factors are as follows:
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.
