Maintenance and Cleaning
Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents.
Take particular care of the reception lens (10), which must be handled with the same level of care you would give to a pair of glasses or a camera lens.
Send in the measuring tool if it requires repair.
