Function Options Info
MRS set 1 ... 2 If you enter both activation codes, you have two
independent parameter sets available for
measuring range switching. The submenus are
the same for both sets.
MRS Selection
• Off
• On
Factory setting
Off
Switches the function on or off
Sensor Selection
• None
• Connected conductivity
sensors
Factory setting
None
This function can be used on conductivity
sensors only.
Binary input 1 ... 2 Selection
• None
• Binary inputs
• Fieldbus signals
• Limit switches
Factory setting
None
Source of the switching signal, can be selected
for input 1 and 2 in each case
Measuring range 00 ...
11
Select the MRSs; a maximum of 4 are possible.
The submenus are identical for each and thus
are displayed only once.

Various methods are available to compensate for
the temperature dependency. Depending on your
process, decide which type of compensation you
want to use. Alternatively, you can also select
None and thus measure uncompensated
conductivity.
