4. IR MEASURING PROCEDURE
4-1 General IR Measurement
Measuring consideration of the " Emissivity "
All objects emit invisible energy. The amount of energy
is emitted proportional to the object's temperature & its
ability to emit energy. This ability is called emissvity
based upon the material that object is made of and its
surface roughness. Emissivity values range from 0.1 for a
very reflective object to 1.00 for a black body.
The probe of this IR THERMOMETER senses
energy and calculates the temperature based on the
amount of IR energy it receives and a factory set
emissivity value is 0.95, which will cover 90% of
the typical applications. However if the emissivity
value of the measured material is not 0.95, then
should adjust the " Emissivity Value ".
The procedure of the emissivity adjustment,
please refer to " 4-5 How to Calculate & Adjust
the Emissivity, page 10 "
1) Power On :
Power on the meter by pressing the " Power Off/On Button "
( 3-2, Fig. 1 ).
The display will count down from " 99999 ", " 88888 ", .......
to " 00000 ", then show the IR temperature value ( approx.
room temperature value ) & the emissivity value on the
right bottom corner of the LCD.
