• Removetheatbatteryfromthebatteryclipandconnectanewbatteryofthesametypewith
the correct polarity to the battery clip.
The battery clip is constructed so the battery can be connected only with the correct polarity.
Do not use force when plugging in the battery.
• Replace the cover of the battery compartment again and secure it with the previously
loosened screw.
10. Operation
a) Function
• Infrared thermometers measure the surface temperature of an object. The sensor of
thedeviceanalysestheemittedandreectedheatradiationoftheobjectmeasured,and
converts this information into a temperature value.
• Emissivity is used to describe the energy emission characteristics of a material. The higher
the emission level, the more radiation a material can emit.
• Many organic materials and surfaces have an emission level of approx. 0.95.
• Metallic surfaces or shiny materials have low emissivity. This results in imprecise measuring
values. For this reason, the emission level can be set.
b) Measuring
• Point the measuring hole, preferably at a 90° angle, at the object to be measured. Make sure
the object to be measured is not smaller than the IR measuring spot of the device.
• Press and hold the measuring button. The measuring value is indicated on the display. The
displayed measurement value corresponds to the average surface temperature of the IR
measuring spot. During measurement, the SCAN indicator is shown on the display.
• After releasing the measuring button, the last measured value will be displayed for approx.
8 seconds for improved readability. The HOLD indicator also appears.
• About 8 seconds after releasing the measuring button, the device turns off automatically.
• Horizontal bars appear on the display if the temperature range is exceeded.
