Measuring D.O.
NOTE
When connecting an grounded PC/printer, measurements cannot be
performed in grounded media as the values would be incorrect
.
The USB interface is not galvanically isolated.
Salinity correction
When measuring the concentration of solutions with a salt content of more than
1 g/l, a salinity correction is required. For this, you have to measure and input
the salinity of the measured medium first. When the salinity correction is
switched on, the
[SAL]
indicator is displayed in the measuring window.
Stability control
(AutoRead )
The stability control function (
AutoRead
) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values (see section 10.2.3 A
1.

You can switch the salinity correction on or off and enter the salinity
in the menu for calibration and measurement settings (see section
