Inserting the battery / replacing the battery
Make sure that the polarity is correct when inserting the batteries. Remove the batteries if
you are not using the device for an extended period of time to prevent damage to the device
by leakage. Leaking or damaged batteries may cause caustic burns if they come into con-
tact with skin. Therefore, use suitable protective gloves to handle damaged batteries.
Keep batteries out of the reach of children. Do not leave batteries lying around openly.
There is a risk of them being swallowed by children or pets. Always replace the whole set of
batteries. Mixing old and new batteries may cause the batteries to leak, which will result in
damage to the device.
Never try to disassemble batteries and avoid short-circuits and contact with fire. Never try
to charge non-rechargeable batteries. There is danger of explosion!
Replace the battery when the "Battery empty" symbol (19) is displayed.
1. Press the button for opening the battery compartment (10), open the battery compart-
ment lid (11) to open the battery compartment(12).
2. Remove the used battery from the battery clip and connect a battery of the same type to
the clip with the correct polarity. The battery clip is designed so that the battery can only
be connected with the correct polarity. Do not apply any force when connecting the bat-
tery.
3. Close the battery compartment (12) again by closing the battery compartment lid
(11).
For replacement batteries, we recommend Conrad item no. 65 25 09.
Operation
Mode of operation
Infrared thermometers measure the surface temperature of an object. The sensor of the device mea-
sures the heat radiation emitted, reflected and transmitted by the object and calculates a temperature
value.
The emission level is a value used to describe the energy radiation characteristics of a material. The
higher the value, the more capable the material is of emitting radiation. Many organic materials and sur-
faces have an emissivity of approx. 0.95. Metallic surfaces or shiny materials have a lower emissivity;
therefore measuring results are inaccurate. For this reason, emissivity can be adjusted for the infrared
thermometers IR 1000-30D, IR 1200-50D USB and IR 1600-50D USB.
