temperature sensor.
Select Custom to manually adjust the emissivity value or to adjust
to a known temperature. Emissivity is automatically calculated
when adjusting to a temperature. See NOTE below.
Alternatively, use one of the following preset options:
Aluminum (rough) = 0.07
Zinc (Galvanized) = 0.25
Concrete = 0.54
Paint = 0.96

NOTE:
Depending on surface treatment, metals such as blasted steel can
have a broad range of emissivity values. Adjusting to a known
temperature (measured by a direct contact surface temperature
probe) on a representative sample will assist in obtaining an
accurate emissivity value.
