9 Operation
9.1 Distance and precision
Fig. 1
To obtain accurate measurements, consider the following points when measuring:
The measured object must be larger than the IR measuring spot S (g. 1).
The measured object should be at least twice the size of the IR measuring spot S (g. 1).
The smaller the object, the closer it must be to the thermometer.
The D:S ratio is 6:1. At a distance D (g. 1) of 6 cm, the size of the IR measuring spot is
1 cm.
9.2 Surface and environmental constraints
Not all surface materials are suitable for taking measurements. Observe the following con-
straints:
Do not measure surface temperatures of shiny or polished metal surfaces.
Do not measure through transparent surfaces such as glass. It will measure the surface
temperature of the glass instead.
Steam, dust, and smoke can affect the accuracy.

12 Disposal
12.1 Product
Electronic devices are recyclable waste and must not be disposed of in the house-
hold waste. At the end of its service life, dispose of the product in accordance with
applicable regulatory guidelines.
12.2 (Rechargeable) batteries
Remove any inserted (rechargeable) batteries and dispose of them separately from the prod-
uct. You as the end user are required by law (Battery Ordinance) to return all used (recharge-
able) batteries. Disposing of them in the household waste is prohibited.
Contaminated (rechargeable) batteries are labeled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable)
batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our
stores or wherever (rechargeable) batteries are sold. You thus fulll your statutory obligations
and contribute to the protection of the environment.
Before disposal, the exposed contacts of batteries must be fully covered with a piece of ad-
hesive tape to prevent short-circuits. Even if batteries are depleted, the remaining energy can
become dangerous in the event of a short-circuit (bursting, severe heating, re, explosion).
