How to specify the thermal emissivity (
e
e
e
e
e
)
1. Stick black body tape on the object whose temperature is to be measured, or
spray it with black body spray.
2. Set the thermal emissivity value (
e
) on the LCD to 0.95.
3. Press the MEAS key, so as to measure the temperature (T
real
) of the part on
which body tape (or black body spray) is applied.
4. Measure the temperature (T) of the parts to which body tape (or black body
spray) is not applied.
5. Change the thermal emissivity value (
e
).
6. The value of the thermal emissivity (
e
) at which T comes out to be equal to T
real
is the correct value for the inherent thermal emissivity of the body whose
temperature is to be measured.
