Setting the emission coefcient
Table of emission coefcients
A built-in sensor head detects the material/surface-specic infrared rays emitted by every object. The level of
these emissions is determined by the material‘s emission coefcient (0.01 to 1.00). After switching on for the
rst time, the device is preset to an emissivity coefcient of 0.95, which is suitable for most organic materials
as well as plastics, ceramics, wood, rubber and stone. For materials with different emissivity coefcients,
please refer to the table under point 6.
Unknown emission coefcient:
Apply masking tape or black matt paint to the surface of the area whose temperature you wish to measure.
Wait until the tape/paint has heated up. The temperature of the surface can then be measured with an
emission coefcient of 0.95.
Button pressed briey: Value +0.01
Keep button pressed:
Value runs through 0.01 … 1.00
Metals
The emissivity coefficient last selected is set after the device is switched on. Check the emissivity
coefficient setting before each measurement.
