2. The unit cannot measure through transparent
surfaces such as glass. It will measure the surface
temperature of the glass instead.
3. Steam, dust, smoke, etc. can prevent accurate
measurement by obstructing the unit´s optics.
8.4 How to optain Emissivity ?
Press the ON / OFF switch. Press the MODE button to
select EMS function and keep the laser / backlight button
until the "EMS" icon flashes on the left side the LCD
display.
In the upper area of the LCD-
display appears "ε ="; the
central area of the LCD display shows the infrared
temperature, and the type-K temperature appears at the
bottom of the LCD display.
Place the K-type probe to the target surface and check.
The temperature of the same point with the help of
infrared measurement
If both values are stable, press UP button to confirm.
The calculated emission factor of the object will appear at
the top of the LCD display.
Press the MODE button to switch to the normal
measuring mode.
Note:
1. If the IR value does not match with the TK
measurement value or the infrared and TK
measurement value have been measured at
various points, no or a wrong emission factor will
be determined.
