For the inoLab Level 3 measuring modules:
pH, pH/ION, pH/Cond, pH/Oxi and Multi.
7.1 Settings for ISE
We recommend checking the current settings and correcting
them if necessary before a measurement.
7.1.1 Displaying pH/ISE or measured voltage values
In pH/ISE measurements, inoLab Level 3 enables a rapid
changeover between the display of the pH/ISE value (
pH )
and voltage ( U ).
7.1.2 Setting up the ISE display
Ion-selective electrodes are connected to the pH/U
connector of the measuring module.
The selection of the measured variable
ISE or pH is made in
the main Meas menu. The active pH or ISE setting is marked
with
