12. Cleaning and maintenance

a) General information
• To ensure the accuracy of the meter over a long period of time, it should be calibrated at least once a year.
• The meter is absolutely maintenance-free except for occasional cleaning and battery/rechargeable battery change.
• Regularly check the device for technical safety, for example, for damage to the casing or deformation, etc.
b) Cleaning the casing
Always observe the following safety information before cleaning the device:
• Do not use abrasive detergents, petrol, alcohol or other similar chemicals to clean the device. These may corrode
the surface of the measuring instrument. 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) Cleaning the sensor
• Remove loose particles with clean compressed air and wipe off remaining residue with a fine lens brush. Clean the
surface with a dry lens cloth or a clean, soft, lint-free cloth.
• Do not use acidic, alcoholic or other solvents or rough, fuzzy cloth to clean the sensor.
• Avoid applying too much pressure when cleaning the lens.
