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 35 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 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.
