Conductivity measurement
1.
Select the desired mode (S/cm) by pressing
MODE
. The display will immedi-
ately show the measured value 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 + max. 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 30°C. When no Pt1000 is used, do not forget
to compensate manually first! Select [CALIBRATE], press
OK
and follow the
in struc tions 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).

Temperature compensation:
1.
Press

3.
Select the temperature to which all future mea sure ments will be refer red to
(25°C or 20°C) and press
OK
.
Capacitive compensation:
1.
Capacitive compensation in creases accuracy in the very low conductivity rang-
es (<10 µS/cm). Select whether or not this compen sa tion 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 in struc tions on the screen.
Resistivity measurement:
1.
Select the desired mode (
Ω
.cm) by pressing
MODE
. The display will immedi-
ately show the measured value.
Salinity measurement:
1.
Select the desired mode (SAL) by pressing
MODE
. The display will immediately
show the measured value according to the Practical Salinity Scale (PSS-78)
which is based upon standard seawater at 15°C.
TDS measurement:
1.
Select the desired mode (mg/l)(TDS) by pressing
MODE
. The display will imme-
diately show the measured value.
