Cleaning Information

and so on. To be absolutely certain that a cleaning paper is
applicable, please ask the salesperson or the manufacturer.
Immersion oil and other index matching compounds
Do not use immersion oil or other index matching compounds with
optical sensors equipped with recessed lenses. They are liable to
dirty the detector and impair its performance. They may also alter
the property of depiction of your optical device, thus rendering your
measurements inaccurate.
Cleaning the housing and the mainframe
When cleaning either the mainframe or the housing of your
instrument, only use a dry and very soft cotton tissue on the
surfaces and the numeric pad.
Never open the instruments as they can be damaged. Opening the
instruments puts you in danger of receiving an electrical shock
from your device, and renders your warranty void.
