6.5 Thermography Settings
◼ Units – select between Celsius and Fahrenheit.
◼
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.
Typical emissivity for human skin is: 0.98.
To adjust the emissivity ratio:
1.
Tap the EMISSIVITY option on the screen.
2.
Scroll to the correct emissivity ratio and tap the
SET button
◼
Reflected Temperature – Reflected temperature
represents the energy emitted by the surrounding
objects and reflected by the measured surface.
To adjust the reflected temperature:
• Tap the Reflected Temperature option on
the screen.
• Scroll to the correct temperature and tap
the
SET button
◼
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.
