Topdon TCView TC001, User Manual

Page: 24 / 182

Q: Why is the measured temperature not precise?
A: The temperature resolution of the TC001 is ±2%. And the TC001 provides a
normal temperature range of -20~150°C (-4~302°F), and a high temperature
range of 150-550°C (302~1022°F). Please select the corresponding range in the
app before measuring.
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.
