Fig. 1: Cuvette positioning (Ø 24 mm):
I. Seal
II. Marking with the white triangle
4. For the zero correction and test, the cuvette must be positioned in the
sample chamber in such a way that the marking with the white triangle (II.)
points towards the housing marking.
5. You must carry out the zero correction and test with the cuvette lid closed.
You must provide the cuvette lid with a sealing ring (I.) to prevent the
entrance of light into the sample chamber.
6. Formation of bubbles on the inside walls of the cuvette will result in faulty
measurements. Should this happen, seal the cuvette with the cuvette lid
and tip it back and forth to dissolve/remove the bubbles before carrying
out the test.
