• Do not insert any objects into the measurement aperture for
cleaning. The instrument could get damaged - affecting a pro-
per and safe operation.
• The instrument housing is resistant to a number of solvents, but
cannot be guaranteed to withstand all chemicals. You should
therefore use a soft, moist cloth for cleaning. For cleaning
excessive dirt, use ethanol or cleaning alcohol.
Do not use any
acetone!

Cleaning standards
The accuracy of the measurement can be significantly impacted
by using dirty or damaged standards.
Since the surfaces of the standards are highly sensitive, cleaning
must be undertaken with great care.
To clean standards, use a new lint-free cloth, dust-free lens
paper or an optical cloth.
Apply only slight pressure as you clean and make certain there
are no large particles stuck in the cloth that could damage the
surface.
Do not use any acetone!
For dirt that is difficult to remove, use an optical cloth dipped in
liquid. Then wipe the surface with a dry optical cloth.
Exact calibration is not possible unless the standard is in perfect
condition. If the condition of the standard seems doubtful
because of its appearance or measurement errors, we will be
happy to check it for you.
