INFRARED THERMOMETER -50°/1350°
Emissivity / Settings emissivity
Emissivity describes the energy-emitting characteristics of materials. Most ( 90% of typical applications ) organic
materials and painted or oxidized surfaces have an emissivity of 0.95 ( preset in the thermometer ). lnaccurate
readings will result from measuring shiny or polished metal surfaces. To compensate, caver the surface to be
measured with masking tape or fi at black paint. Allow time for the tape or paint to reach the same temperature as
the surface beneath it. Measure the temperature of the tape or painted surface

The thermometers allow you to adjust the thermometer's emissivity setting value so as to match the type of surface
to be measured.
How to set emissivity
1. When the thermometer is on, press and hold down the "MODE " button until the symbol "E " fl ashes, then release
the button.
2.Press the button to decrease or the button to increase the emissivity setting value.
3.When you fi nish emissivity setting, press and hold down the "MODE "button until the symbol "E "stops fl ashing.
The thermometer returns to normal operation.
