Ph Measurement; Mv Measurement; Conductivity Measurement; Inputs - Consort C533 Anleitung

The measuring electrodes should be connected to the corresponding coaxial pH/
mV or EC/O connectors. Automatic temperature compensation and temperature

measurements are possible by plugging a Pt1000 temperature probe into the °C
terminals. You can also use an electrode with built-in Pt1000. Its banana plugs
should be inserted in the °C terminals. Without Pt1000, the manual temperature
compensation is automatically switched on.
• Never immerse a pH electrode and an oxygen electrode together in the same
solution!
• A blinking decimal point warns you for unstable measurements. Wait to read
the display!
• Stirring the solution during the measurements promotes the homogeneity and
is obligatory!
• The instrument will refuse automatic calibration when the electrode is unsta-
ble. Insufficient stirring or a worn electrode may be the cause.
1. Select the pH range by pressing MODE. The display will immediately show the
measured value according to the previous calibration. Should you want to rec-
alibrate, press CAL.
2. The display shows two of the 9 buffers in memory, e.g. [7.00] and [4.00].
Select the proper buffers and press CAL. The unused buffer should be switched
off.
3. Rinse the electrodes with distilled water and immerse them in the first buffer
solution. Select [CALIBRATE], press CAL and follow the instructions on the
screen until the calibration is finished.
4. After rinsing the electrodes with distilled water, immerse them in the samples
and read the display.
5. Rinse the electrodes always with distilled water after use and store them in a
3...4 M KCl solution.
1. Select the mV range by pressing MODE. The display will immediately show the
measured value according to the previous calibration (optional). Should you
want to recalibrate, press CAL.
2. Immerse the electrodes in a standard solution of known potential. Select
[CALIBRATE] and press CAL. Calibrate to the proper value and press CAL again
or press MODE to reset the factory settings.
3. Rinse the electrodes always with distilled water after use and store them in a
3...4 M KCl solution.
1. Select the conductivity range (µS/mS) by pressing MODE. The display will
immediately show the measured value according to the previous calibration.
Should you want to recalibrate, press CAL.
2. The display shows one of the 3 standards in memory (not C532). Select the
proper standard and press CAL. Also select the temperature to which all future
measurements will be referred 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 instructions on
the screen until the calibration is finished.
4. 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).
