Conductivity measurement
Measurement:
1. Select [S/cm] by pressing MODE . The display will immediately show the meas-
ured value according to the previous calibration. Should you want to recali-
brate, press CAL .
2. The display shows the three standards in memory (1413 µS/cm, 12.88 mS/cm,
111.8 mS/cm). Select the proper values or enter manually special values and
press CAL . The unused standards should be switched off.
3. Select the temperature to which all future measurements will be referred to
(REF=25°C) and press CAL .
4. Select whether or not automatic temperature compensation (ATC) should be
applied and press CAL .
5. 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 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.
6 . Rinse the electrode several times with the sample, immerse it in that solution
and read the display.
7 . Rinse the electrode always after use and store it in distilled water (add some
detergent to keep the spongy platinum surface in perfect condition).
• 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.
Capacitive compensation:
1. Capacitive compensation increases accuracy in the very low conductiv-
ity ranges (<10 µS/cm). Select whether or not this compensation should be
applied. Verify if the attached electrode is completely dry and press
CAL.
Select [COMP.ON] or [COMP.OFF] and press
CAL
. Follow the instructions on the
screen.
TDS measurement
1. Select [TDS] by pressing MODE . The display will immediately show the meas-
ured value according to the previous calibration. Should you want to recali-
brate, press CAL . Proceed as for conductivity.
Resistivity measurement
1. Select [ Ω .cm] by pressing MODE . The display will immediately show the meas-
ured value according to the previous calibration. Should you want to recali-
brate, press CAL . Proceed as for conductivity.
Salinity measurement
1.
Select [SAL] by pressing
MODE
. The display will immediately show the meas-
ured value according to the previous calibration. Should you want to recali-
brate, press
CAL
. Proceed as for conductivity.
µW measurement
1. Select [µW] by pressing MODE .
2. After calibrating and rinsing the pH, ORP and conductivity electrodes with dis-
tilled water, immerse them in the solution to be measured and read the power
in µW.
