Electrical conductivity measurement is set to µS/cm as default. In some countries, ppm (parts
per million) is used instead. Conversion 1μS/cm = 0.5 ppm. Set the desired unit using the code
switch
a
. This setting will then apply to all conductivity readings and set values.
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
