IR thermometers measure the surface temperature of an object. The sensor of the device analyzes the emitted and reflected
heat radiation of the object measured, and converts this information into a temperature value.
In the case of any damages which are caused due to failure to observe these operating instructions, the guarantee will
expire. We do not assume liability for resulting damages! Nor do we assume liability for damage to property or personal
injury, caused be improper use or the failure to observe the safety instructions. The guarantee will expire in any such case!
Laser radiation can cause irreparable eye damage. When measuring near humans or animals, switch the laser beam off.
Temperature measurement
Aim the opening of the IR sensor at the object or surface to be measured and press the button "MEAS". The red laserpoint
becomes visible. The temperature will be measured and displayed as long as the button is kept pressed("SCAN" appears on
the display). After button release, the last measured value will be displayed on the LC display ("HOLD" appears on the
display).
After about 7-8 seconds the IR thermometer will automatically turn off.
Please bear in mind that the object/surface to be measured is larger than the measuring spot ("Distance to spot ratio", D/S).
In the case of this IR thermometer, the distance to spot ratio is 6:1. This means that e.g. at the IR sensor's distance of 60cm
to the surface, the measuring spot has a diameter of approximately 10cm. And at the distance of 120cm, the diameter of the
measuring spot is about 20cm. The temperature displayed on the IR thermometer is, in this case, an average temperature of
this measuring spot! Due to the arrangement in the housing, the distance from the laser spot to the centerline of the
measuring spot is about 13mm.To achieve precise measurement values, the object must be at least twice as large as the
measuring spot (if necessary, reduce the distance from the IR thermometer to the object).
Tips & notes
• When measuring extremely high and low temperatures, (e.g. 0°C and 200°C), a pause of half an hour between the
measurements should be done. This pause is necessary for cooling down of the IR sensor. Otherwise the displayed
temperature values can deviate from the actual ones.
• Please clean the surface of the IR sensor with a clean, soft brush or a vacuum cleaner.
• The emission ratio (for the IR thermometer it has been preset at 0.95) specifies energy radiation characteristics of a
material. The higher this value, the more radiation (heat radiation) a material can emit.
• Many materials have a value which is close to the preset value of "0.95" of the IR thermometer. Metal or shiny surfaces
have a low emission ratio. This result in imprecise measurement values during the measuring procedure.
• Applying an adhesive tape (or, if possible, varnishing with a faint black paint) could help to get more precise values.
• It is not possible to measure the temperature through a glass plate. In such a case you will just get the temperature of the
glass plate itself.
Batteries and environmental notes.
As an end user you are legally obligated (Battery regulation) to dispose of used batteries and accumulators correctly; it is not
permitted to dispose of used batteries/accumulators in the domestic refuse! Thus, you comply with your legal obligations and
make your contribution to environmental protection. Batteries/accumulators containing harmful substances are marked with
the following symbols which point out that they are not allowed to be disposed of in the domestic refuse. The markings for
hazardous heavy metals are: Cd = Cadmium, Hg = Mercury, Pb = Plumb (the marking is on the battery/accumulator under
the dust bin symbols painted left).You can return used batteries/accumulators free of charge to any collecting point in your
local authority, or in any store where batteries/accumulators are sold.
