Conductivity/Tds/Salinity/Resistivity Measurement - Consort C32 Serie Anleitung

Conductivity/TDS/Salinity/Resistivity measurement

Conductivity measurement
Select the desired mode (S/cm) by pressing   . The display will immediately show the measured value
1.
according to the previous calibration. Should you want to recalibrate, press CAL.
2. The instrument permits to choose between the standards in memory (1413 µS/cm, 12.88 mS/cm, 111.8
mS/cm + up to 3 user tables). Select the proper values and press OK. The unused standards should be
switched off.
3. After rinsing the electrode several times with the first standard solution, immerse it in that standard. The
solution temperature is not so critical but should lie between 0°C and 40°C. When no Pt1000 is used, do
not forget to compensate manually first! Select [CALIBRATE], press OK and follow the instructions on
the screen until the calibration is finished.
4. Rinse the electrode several times with the sample, immerse it in that solution and read the display.
5. Rinse the electrode always after use and store it in distilled water (add some detergent to keep the
spongy platinum surface in perfect condition).
1. A blinking decimal point warns you for unstable measurements. Wait to read the display!
2. Stirring the solution during the measurements promotes the homogeneity and is obligatory!
3. The instrument will refuse automatic calibration when the electrode is unstable. Insufficient stirring or a
worn electrode may be the cause.
4. When starting a titration, hold MODE pressed and press ê to lock the actual range and avoid cross-over
errors due to differences in the measuring frequency. Hold MODE pressed and press
again to the normal measuring mode.
Temperature compensation
1. Press CAL.
2. Select [REF.] and press OK.
3. Select the temperature to which all future measurements will be referred to (25°C or 20°C) (C305x:
20°C...40°C in 1°C steps) and press OK. Select the value 0 to disable the temperature compensation
and read absolute conductivity measurement values.
Capacitive compensation
1. Capacitive compensation increases accuracy in the very low conductivity ranges (<10 µS/cm). Select
whether or not this compensation should be applied. Verify if the attached electrode is completely dry
and press CAL.
2. Select [CAP.COMP] and press OK.
3. Select [YES] or [NO] and press OK. Follow the instructions on the screen.
TDS measurement
Select the desired mode (mg/l)(TDS) by pressing   . The display will immediately show the measured
1.
value.
Salinity measurement
Select the desired mode (SAL) by pressing   . The display will immediately show the measured value.
1.
Resistivity measurement
Select the desired mode (W.cm) by pressing   . The display will immediately show the measured
1.
value.
