10 Configuration

In the configuration the devices parameters can be changed.
The jumper has to be set, p.r.t. figure right hand side. To set or
remove jumper, the housing cover has to be removed. Ex works
the jumper is set.
To change parameters press “SET” (key 1) two seconds, then the
parameter selection is started with the first parameter (display
shows “CELL”).
By pressing “SET” the desired parameter is selected, the editing of
the parameter values happens via keys 

5

 (key 3) or 

6

 (key 2).

Pressing “SET” again (after editing the parameter values) returns
to the parameter selection
Pressing “SET” again after the last parameter finishes the configu-
ration, stores the changes and restarts the device.

10.1  'CELL': Setting of the cell-constant of the connected measuring cell

Possible inputs: 0.300...1.200. Unit is 1/cm.
The value was evaluated and stored ex works for the connected measuring cell (in between 0.45...0.65).

10.2  'Func': Setting of the measuring function

Possible inputs:

cond  conductivity
reSi:

resistivity

tdS:

TDS (total dissolved solids

SAL: Salinity = salt content of sea water

10.3  'rAnG': Setting of the measuring range (not at “Func SAL”)

Choice the desired measuring range (range is depending on the function set above).
Possible inputs:

Range (rAnG) r 4

Range (rAnG) r 3 Range (rAnG) r 2 Range (rAnG) r 1

Range (rAnG) r 0

Conductivity (cond) 0 - 500 mS/cm

0,0 - 200,0 mS/cm

0,00 - 20,00 mS/cm 0 - 2000 µS/cm

0,0 - 200,0 µS/cm

Resistivity (rESi)

1,00 - 50,00 Ohm·cm 1,0 - 500,0 Ohm·cm 1 - 5000 Ohm·cm

0,00 - 20,00 kOhm·cm 0 - 200 kOhm·cm

TDS (tdS)

0 - 1000 g/l

0.0 - 200,0 g/l

0.00 - 20,00 g/l

0 - 2000 mg/l

0,0 - 200,0 mg/l

Salinity (SAL)

0,0 - 70,0

10.4  't.Cor': Setting of temperature compensation method (not at “Func SAL”)

Possible inputs: off:  no temperature compensation

nLF:non linear compensation for natural water according to EN 27888 (DIN 38404).

 

For measurings of ground and surface water, drinking water or pure water.

 

Attention: restricted temperature range: -5..105 °C

 

Lin: linear temp. compensation (for other aqueous solutions, factor has to be entered)

10.5  't.Lin': Setting of temperature coefficient (only for t.Cor = Lin)

Possible input: 0.300 .. 5.000 [%]
If it is only measured in a narrow conductivity range, the temperature compensation factor of this range can
be determined.

10.6  't.rEF': Setting of reference temperature (only for t.Cor = nLF or Lin)

Possible input: 20 °C or 25 °C

10.7  'C.tdS': Setting of TDS-factor

Calculation factor for TDS (Total Dissolved Solids)-measurements, possible input: 0.40 .. 1.00.
The calculation factor depends on the composition of the medium and has to be determined
for each type of water.

If the jumper is removed from
the shown contacts, the con-
figuration is inaccessible, val-
ues are protected.
