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
Personal Information, and turn off Auto shutter.
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 reect 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.
