Turbidity correction
Turbidity correction is used in sample solutions that
contain finely distributed suspended particles.
The suspended particles cause a light absorption.
This leads to incorrect (too high) measured values.
The function remains permanently switched on after it
has been activated. Values that were measured using
turbidity correction are given an identifier in the display
and in the documentation (printout and storage).
The turbidity correction function is not active when de-
livered.
This function is not necessary, or useful,
in all methods. If the turbidity correction is
active, the photometer automatically de-
cides whether to perform the function or
not depending on the method.
