19. Cleaning and maintenance

a) General information To ensure the accuracy of the data logger over a long period of time, it should be calibrated at least once a year. The meter does not need to be serviced (apart from occasional cleaning and replacing the battery). Refer to the following sections for instructions on how to change the battery. Regularly check the device for technical safety, for example, for damage to the casing or deformation, etc. 2b) Cleaning Do not use abrasive detergents, petrol, alcohol or other similar chemicals to clean the device. These may corrode the surface of the meter. In addition, the vapours emitted by these substances are explosive and harmful to your health. Do not use sharp-edged tools, screwdrivers or metal brushes to clean the device. To clean the device and the display, use a clean, lint-free, antistatic and slightly damp cleaning cloth. Allow the device to dry completely before using it again. c) Inserting/changing the battery ACR24503Vlithiumround-cellbatteryisrequiredtooperatethemeter.Beforerstuseorwhenthebatterychange symbol“ ” appears on the display, be sure to insert a new, fully charged battery. Changing the battery will not delete any data or settings.60 Proceed as follows to insert/replace the battery:

• Remove the protective cap (12) from the data logger.

• Press and hold down the battery compartment release button (7) and gently take the logger unit out of its casing. Theloggerunitsitsrelativelyrmlyinthecasingthankstothesecondrubberseal(9).
