Setting the emission coefficient
5
A built-in sensor head detects the material/surface-specific infrared rays emitted by every object. The level of
these emissions is determined by the material's emission coefficient (0.01 to 1.00). After switching on for the
first time, the device is preset to an emissivity coefficient of 0.95, which is suitable for most organic materials
as well as plastics, ceramics, wood, rubber and stone. For materials with different emissivity coefficients,
please refer to the table under point 6.
Unknown emission coefficient:
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 coefficient of 0.95.
The emissivity coefficient last selected is set after the device is switched on. Check the emissivity

coefficient setting before each measurement.
