Cleaning and Maintenance
16. Cleaning and Maintenance
• Do not insert any objects into the measurement
aperture for cleaning. The instrument could get
damaged.
• Do not use any acetone for cleaning the
unit! 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 attempt to make any repairs yourself! If a
malfunction occurs on your measuring device,
our Customer Service department will be happy
to help you as quickly as possible.
Cleaning standards
Do not use any acetone!
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.
The best cleaning results are achieved when
moving the optical cloth from left to right, not
wiping in circles.
For dirt that is difficult to remove, use an optical
cloth dipped in liquid. Then wipe the surface with
a dry optical cloth.
It is highly recommended to handle the
standards with great care. They should always
be stored enclosed.
