9. Cleaning and maintenance
Apart from occasional cleaning and battery replacements, the meter requires no servicing.
Before cleaning the device, switch it off and disconnect it from the USB cable.
Do not use any aggressive cleaning agents or petrol, alcohol or the like to clean
the product. They will damage the surface of the camera/housing. Furthermore, the
fumes are hazardous to your health and explosive.
Use a clean, lint-free, antistatic, slightly damp cloth for cleaning the device or the display. Do
not push the surface too much when cleaning to avoid scratches. Allow the product to dry
completely before you use it again.
