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.

If necessary, press the

<M>

key several times until the measured pa-

rameter

is selected.

Press the

<CAL/ZERO>

key.

The menu for adjustment measurements opens up.
