Open the protective cover at the inside of the measuring
unit and position the cell at the centre between maximum
and minimum range (around 60 mm). Loosen the screws at
the left side of the cell holder by using a 3-mm Allen key
and remove the cell by lifting and pulling it forward.
Disconnect the hoses from the cell.
Cut the hoses, if they
are hard to remove
. By proceeding as described above,
the ball bearing of the cell will not be damaged, while the
cell interior is protected against contamination.
Prior to dismantling the measuring cell and cleaning the
window, spacer and seals, prepare a spray bottle with dis-
tilled water. and have special lens cleaning tissues handy.
Clean the devices on a clean working surface.
Use a 2-mm Allen key to loosen the 4 screws that hold to-
gether the two sections of the measuring cell and carefully
remove one half of the cell. Ensure that the windows (2)
(two optical glass panes with parallel faces) remain in their
frames! The outside of the windows is equipped with a anti-
reflex coating that is easily damaged.
