1 Loosen and remove the knurled screws (4-3).
2 Remove the cover plate (4-2).
3 Insert the flow-through cell (6.2839.130) such that the opening in
top right corner is aligned with the cylinder screw (4-4) on the cell
block.
4 Screw in the knurled screws again.
NOTE
In order to fix the flow-through cell in the correct position, the
two knurled screws must be tightened symmetrically and with
constant force.
Any tilting, twisting or canting of the flow-through cell influences
the light incidence and thus the measuring results.
