Maintenance
The measuring accuracy could be compromised if the lens is not clean.
Use a camera blower to clean the lens. If it is still dirty, use a cotton swap soaked in a lens cleaning
solution to wipe the stain away.
Caution:
Never use water or any other cleaning solvent to clean the lens. Doing so could damage the
lens, causing the efficiency of the lens and measurement accuracy to fall.
