Adjusting Emissivity
–Emissivity is the ability of
the surface of a material to emit energy as thermal
radiation. The emissivity value (0
– 1) represents
the ratio of energy radiated by the observed
material to the energy radiated by a black body at
the same temperature.
To adjust the emissivity ratio:
– Tap the
Emissivity
option on the screen.
– Scroll to the correct emissivity ratio and tap the
Set
button.
Adjusting the Reflected Temperature
– Reflected
temperature represents the energy emitted by the
surrounding objects and reflected by the measured
surface. Setting this value accurately is important if
the emissivity value is low.
To adjust the reflected temperature:
– Tap the
Reflected Temperature
option on the
screen.
– Scroll to the correct temperature and tap the
Set
button.
Adjusting the Scale Truncation
–Within every
image frame, the temperature span is calculated
and displayed on the top of the thermography
image. Use this parameter to define the minimum
number of pixels (defined by percentage) required
to affect the temperature span calculation.
To adjust the truncation value:
– Tap the
Scale Truncation
option on the screen.
– Scroll to the correct temperature and tap the
Set
button.
