Measuring principle
The device measures the temperature by means of an infrared
sensor. Important factors are the measuring spot diameter and
the degree of emission.
Measuring spot
Observe the ratio of the distance to the measuring spot
diameter. The larger the distance to the object, the larger the
measuring spot diameter and hence, the less precise the
measured result.
The connectable laser pointer indicates the approximate
measuring spot centre. Consequently, it is a mere aiming aid
and not intended for the actual temperature measurement.

Degree of emission
The degree of emission is used to describe the energy radiation
characteristics of a material.
A material's degree of emission depends on various factors:
• composition,
• surface condition,
• temperature.
The degree of emission can be between 0.1 and 1(, in theory).
The following rule of thumb can be assumed:
• When a material is rather dark and its surface texture matt,
it probably has a high degree of emission.
• The brighter and smoother the surface of a material, the
lower will be its degree of emission, presumably.
• The higher the degree of emission of the surface to be
measured, the better it is suited for non-contact
temperature measurement by use of a pyrometer or
thermal imaging camera, since falsifying temperature
reflections can be neglected.
Entering a degree of emission as accurate as possible (if
possible with this device) is indispensable for a precise
measurement.
Most organic materials have a degree of emission of 0.95.
Metals or shiny materials come with a much lower value.
Maintenance and repair
Cleaning
Clean the device with a soft, damp and lint-free cloth. Ensure
that no moisture enters the housing. Do not use any sprays,
solvents, alcohol-based cleaning agents or abrasive cleaners,
but only clean water to moisten the cloth.
Repair
Do not modify the device or install any spare parts. For repairs
or device testing, contact the manufacturer.
Battery change
A battery change is required when the battery status indication
flashes or the device can no longer be switched on (see chapter
Inserting the batteries).
