lation, removal, connecting cables).
Danger
Switching the unit of measurement/changing the function
Electrical conductivity is measured in µS/cm. In some countries, ppm (parts per million) is used
instead. Conversion 1μS/cm = 0.5 ppm. Set the desired unit using code switch c. This setting
will then apply to all conductivity readings and set values. If you set the equipment to ppm, please
stick the supplied adhesive sign over the unit on the terminal box.
To change the setting, proceed as follows:
■ Insert a screwdriver between the terminal strip and the front frame, at the arrow markings on
the right and left.
■ Release the terminal strip on the right and left by turning the screwdriver in the direction of the
arrow.
■ Detach the terminal strip.
■ Set code switch c as shown in the table below.
■ Insert the lower terminal strip.
■ Switch the supply voltage back on. The equipment restarts.
