FIELD OF VIEW
Make sure that the target is larger than the spot size.
The smaller the target, the closer you should be to it.
See Figure 7.
EMISSIVITY
Emissivity describes the energy-emitting characteristics of materials. Most organic materials
and painted or oxidized surfaces have an emissivity of about 0.95.
If possible, to compensate for inaccurate readings that may result from measuring shiny
metal surfaces, cover the surface to be measured with masking tape or flat black paint (<150
ºC/ 302 ºF) and use the high emissivity setting. Allow time for the tape or paint to reach the
same temperatures as the surface beneath it. Measure the temperature of the tape or painted
surface.
If you cannot use paint or use tape, then you could improve the accuracy of your
measurements with the emissivity selector. Even with emissivity selector, it can be difficult to get
a completely accurate infrared measurement of a target with a shiny or metallic surface.
USER SETUP
Press SET button to step through Emissivity Setup Trigger Lock Switching ºC/ºF Normal
Measurement.
Press YELLOW button to save and exit Setup.
EMISSIVITY SETUP
This feature is to change the value of emissivity. To adjust values for emissivity, follow the
below procedure:
1. Press SET to select emissivity set up, icon E=0 on the display is blinking.
2. Press
to increase the value by 0.01 or press and hold
maximum value is 1.00.
3. Press
to decrease the value by 0.01 or press and hold
The minimum value is 0.10.
The Thermometer allows you to adjust the unitís emissivity for the type of surface before
measured.
Refer to Table 2. But it is only a typical case. You could base on your own case and materials
to have different setting.
