5. Storage and Maintenance
(1)
Store this instrument
in
a dry and shaded area. A
damp storage area may cause the optical system
to
blur or encourage molding. Extended exposure
to
direct sunlight may cause the casing to warp.
(2)
Do
not use organic solvents (paint thinner,
benzene, gasoline, etc.)
on
the instrument
because
it
will severely damage the casing.
(3)
Clean the prism
surface
immediately
after
completing each measurement. Any sample left
on
the prism surface for
an
extended period of
time will damage the prism. Clean the prism with
water and then dry any excess moisture with a
clean, dry tissue.
