[. . . ] Consequently you comply with your legal obligations and contribute to environmental protection!This product is designed for temperature measurement and is especially suitable for use in laboratories and industrial areas. The product can calculate the difference between two temperature readings and display the result. Measurements should not be carried out under unfavourable ambient conditions. This product fulfils European and national requirements related to electromagnetic compatibility (EMC). cE conformity has been verified and the relevant statements and documents have been deposited at the manufacturer. Unauthorised conversion and/or modification of the device are inadmissible because of safety and approval reasons (CE). Any usage other than described above is not permitted and can damage the product and lead to associated risks such as short-circuit, fire, electric shock, etc. â· Batteries should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries. Do not leave the battery lying around, as there is risk, that children or pets swallow it. Using the HOLD or MAX/MIN buttons, you can switch between types K and J. Using the HOLD or MAX/MIN buttons, you can switch between SLP ON (auto-off function on, clock symbol appears top-right in display) and SLP OFF (auto-off function off, clock symbol no longer displayed). Turn the thermometer on and place the relevant sensor in an optional temperature calibrator or in any other reference location with a known and stable temperature. If there is a difference, you can manually compensate it (see section "Adjusting settings"). After you have manually compensated a deviation, the top display will then show the OFFSET indicator in normal display mode.
