4.5.7 Zero adjustment
The zero adjustment, i. e. measuring and storing the absorbance of a cell
filled with water, is necessary after the meter is switched on.
Additionally, we recommend to carry out a zero adjustment if the ambient
temperature has changed.
Only perform the zero adjustment against distilled water in an optically per-
fect cell. The zero adjustment must be performed separately for each cell
type.
