Emissivity of Materials
The infrared temperature sensor reacts to the
thermal energy (infrared radiation) emitted by an
object. The ability to radiate heat depends on the
type of material and its surface properties. Shiny
metals or aluminium, for example, have a very low
emissivity coefficient. An infrared temperature
sensor which has been calibrated by a black body
will detect less infrared radiation when measuring
a material with low emissivity. In such cases, you
should select a lower switching temperature.

5 Electrical connection

The infrared temperature sensor may only be
installed by a skilled, qualified electrician. Do not
connect the instrument while the voltage supply
source is turned on. Please observe internation-
al safety regulations at all times.
► Switch to neutral and verify absence of voltage.
► Connect instrument according to the following
schematic:
