5.2.2 Cleaning the cells

Cells have to be clean, dry, and free of fingerprints. Therefore, clean them

regularly:

Clean the cells inside and out with hydrochloric acid or laboratory

soap.

Rinse out several times with distilled water.

Let them dry in the air.

Only hold the cells by the top or by the light protection cap so that the

optical path is not impaired.

Before measuring, clean the cell with the enclosed cleaning cloth.

We recommend: Keep the packing material. The original packing

protects the meter against damage during transport.

(see section 5.1.1).

At the end of its operational lifetime, the meter must be returned to the
