Inputs
The measuring cell should be connected to the coaxial INPUT connector.
Automatic temperature compensation and temperature measurements
are possible by plugging a Pt1000 thermocompensator into the °C
terminals.You can also use a combination conductivity electrode with built
in Pt1000. Its banana plug should be inserted in the upper °C terminal.
Without compensator, the manual temperature compensation is
automatically switched on.
CONDUCTIVITY MEASUREMENT
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!).
Maintenance
The cell constant depends on the physical dimensions of the platinum
plates. They are coated with a spongy black platinum deposit. This
increases greatly the effective surface and reduces polarising effects.
Since the coating of platinum black is quite resistant to chemical action,
the cell constant remains fairly constant during the electrode life time.
Calibration

1. Select the conductivity range by pressing MODE (the display shows
[µS] or [MS]) and press CAL.
2. The display will show the cell constant (e.g. [cc=1.073]). Press CAL
to start the automatic determination procedure.
3. The display shows one of the KCl standard solutions in memory
[St=0.01M] (1413 µS/cm), [St=0.1M] (12.88 mS/cm) of [St=1M]
(111.8 mS/cm). Select the proper standard with ¿or Àand press
CAL.
4. After rinsing the cell several times with the standard solution,
immerse it the standard solution. The solution temperature is not so
critical but it should lie between 0°C and 30°C. If the standard has a
different temperature press °C here (not necessary when using a
Pt1000). Press CAL to continue.
5. The display will show the computed cell constant e.g. [cc1=1.045]
and will calibrate automatically when readings are stable ([=] stops
blinking).
Conductivity
measurement
1. Select the conductivity range by pressing MODE (the display shows
[µS] or [MS]).
2. Rinse the electrodes with the sample and immerse them in it.
3. Read the display (remember: compensated to the reference
temperature!). The autoranging feature gives you the largest possible
number of digits + their unit.
4. Rinse the cell always after use and store it in distilled water (add
some detergent to keep the spongy platinum surface in perfect
condition).
∗Disconnect the AC-adapter to increase accuracy in the lower
conductivity range!
∗See page 41 for the standards in memory.
∗A blinking decimal point warns you for unstable measurements. Wait
to read the display!
∗Press RES to switch between ppm (salinity), S/cm (conductivity) or
Ω.cm (resistivity).
∗When starting a titration, press Àto 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.
∗Stirring the solution during the measurements promotes the
homogeneity and is therefore always recommended.

TEMPERATURE MEASUREMENT
1. Press CAL to calibrate the °C scale with any reference. Immerse the
Pt1000 in a solution of known temperature.
2. The display shows e.g. [°C=22.3]. Calibrate to the proper value with
¿or Àand press CAL again or press RES to reset the absolute
readings.
Calibration
Measurement
1. Read temperature by pressing °C.
2. Without Pt1000, adjust the manual temperature compensation with ¿
or Àand proceed by pressing MODE.
