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 „µS". 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 salt water, the unit has to be recalibrated.
For fresh water, a calibration solution of 250 µS and for salt water a solution of 50 mS is 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.
For fresh water, a second calibration fluid with 500 µS/cm resp. for salt water with 50 mS/cm is 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 plastic shaft. The contact pins are made from carbon and are corrosion 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.
