Prescribed Use
The prescribed use includes the contactless measuring of temperatures from
–20°C to +500°C. To supply the device with voltage only a 9 V compound bat-
tery of type 006P, IEC6F22, NEDA1604 or identically constructed types may
be used. Operation is only permitted in dry environment, contact with damp-
ness is to be avoided by all means.

the measured object, the shorter the distance to the infrared thermometer
needs to be.
The precise measuring spot size can be taken from the diagrams below. They
are furthermore printed on the devises.

Emittance
Emittance is a level that is used to describe the energy irradiation characteris-
tic of a material. The higher this level, the higher the ability of the material to
transmit irradiation. Many organic materials and surfaces have an emittance
of 0.98. Metallic surfaces or shiny materials have a lower emittance and there-
fore provide imprecise measurements. Please take this into consideration
when using the infrared thermometer.
To compensate this, the surface can be covered with sticky tape or with mat
black colour. The devise cannot measure through transparent surfaces such
as e.g., glass. Instead, it will measure the surface temperature of the glass.
