Introduction
Introduction
This instrument is manufactured with the latest technology and needs no particu-
lar maintenance.
Consort
certifies that this instrument was thoroughly inspected
and tested at the factory prior to shipment and found to meet all requirements
defined by contract under which it is furnished. However, dimensions and other

Reference temperature:
1.
Select the temperature to which all future mea sure ments will be refer red to
and press
CAL
.
Cell constant:
1.
Select automatic cell con stant determination or enter manu ally a fixed value
and press
CAL
.
Capacitive compensation:
1.
Capacitive compensation in creases accuracy in the very low conductivity rang-
es (<10 µS/cm). Select whether this compen sa tion should be applied or not.
Verify if the attached cell is completely dry and press
CAL.
Select [COMP.ON]
or [COMP.OFF] and press
CAL
. Follow the in struc tions on the screen.
Measurement:
1.
Select [MAIN MENU], [S/cm] by pressing
MODE
. The display will immediately
show the measured value according to the previous calibration. Should you
want to recalibrate, press
CAL
.
2.
Select the proper standard from one of the values in me mory (1413 µS/cm,
12.88 mS/cm, 111.8 mS/cm) or enter manually a special value and press
CAL
.
Also select the temperature to which all future mea sure ments will be refer red
to.
3.
After rinsing the cell several times with the standard solution, immerse it
in that standard. The solution temperature is not so critical but should lie
between 0°C and 30°C. When no Pt1000 is used, do not forget to compensate
manually first! Select [CALIBRATE], press
CAL
and follow the in struc tions on
the screen until the calibration is finished.

.
Rinse the cell several times with the sample, immerse it in that solution and
read the display.
5
.
Rinse the cell always after use and store it in distilled water (add some deter-
gent to keep the spongy platinum surface in perfect condition).

Stirring the solution during the measurements promotes the homogeneity and
Stirring the solution during the measurements promotes the homogeneity and
is obligatory!
•
The instrument will refuse automatic standardisation when the electrode is
unstable. Insufficient stirring or a worn electrode may be the cause.
•
When starting a titration, press
ê
to lock the actual range and avoid cross-
over errors due to differences in the measuring frequency. Press MODE to
return to the normal measuring mode.
Relative measurements:
1.
While in the conductivity or salinity mode, press
é
. At that moment the
instrument stores the actual value and automatically subtracts it from all next
measurements. You can repeat this as many times as required. A [REL] in the
display appears.
2.
To cancel relative readings, press
MODE
and you will be in the normal measur-
ing mode again.

6.
Prepare the sample solution to be measured in a thermostatic bath with mag-
netic stirrer. Its temperature should be about 5°C lower than the lowest value
you may possibly need during future measurements, but at least lower than
10°C. After rinsing the electrodes with the solution to be measured, immerse
them in that solution. Wait a while to enable the electrodes to adapt them-
selves to the low temperature. Follow the in struc tions on the screen. Slowly
increase the temperature (max. 0.1°C/s) of the thermostatic bath. You can
monitor the temperature and conductivity on the display. When the tempera-
ture is about 5°C higher than the highest value you need for future measure-
ments, press
CAL
to stop the temperature tracing.

Maintenance of conductivity electrodes
Maintenance of conductivity electrodes
A conductivity cell is active and stable only after wetting!
For this purpose it
must be immersed for
at least one hour
in distilled water. Rinse the cell always
after use and store it in distilled water (add some detergent to keep the spongy
platinum surface in perfect condition).
A polluted cell may be cleaned with a soft detergent or diluted nitric acid. Greasy
substances may be removed with acetone or alcohol (never do this with plastic
electrodes!).
