3. Starting/measuring
1. Connect the main plug to 220 V, if not indicated otherwise.
2. Turn switch (3) on M" (measuring).
3. Immerse the top of the conductivity probe into the test liquid, minimum depth 4 cm.
4. Switch the measuring range switch to the right range ( S for pure and fresh water, mS for
brackish and sea water, recalibrate, if necessary.
5. After 3 min. you can read the value.
4. Controlling
1. Switch knob 3 (set/measuring) to „set".
Adjust the desired set point at knob 5 (set point adjustion).
2. Turn switch 3 back to „ S". The unit is now ready to use. As soon as the adjusted set
point is exceeded, the unit activates the socket at the main plug.
5. Calibration
If you change the measuring range between fresh and sea water, the unit has to be recalibrated.
1. For fresh water, a calibration solution of 250
recommended.
-
Immerse the electrode in a calibration liquid of the corresponding range and the exact
temperature. To adjust the display, turn the calibration knob (6 or 7) of the corresponding
range.
2. For fresh water, a calibration second fluid with 500
necessary.
-
Turn a small screw driver through the opening at the bottom of the unit until the display shows
the right value.
If the unit shows a wrong value, it has to be recalibrated.
6. Electrode
The conductivity electrode has a plactic shaft. The contact pins are made from carbon and are
corosion safe, also in sea water in long term use. The electrode is supplied with a thermosensor for
automatic temperature compensation. The electrode is maintenance-free.
