Page 12: Adjustment Of The Temperature Measuring Input
4 | Operation G 1610 Adjustment of the temperature measuring input The temperature input can be adjusted with the zero point correction and the gradient correction. If an adjustment is made, you change the pre-adjusted factory settings. This is signalled with the display text T.OF or T.SL when switching on. Switch the device off. -
Page 13: Measurement Basics
G 1610 Measurement Basics | 5 Measurement Basics The oxygen sensor 5.1.1 Explanation The oxygen sensor is an active sensor. It consists of a platinum cathode, a lead anode and potassium hydroxide (KOH) as an electrolyte. If oxygen is present, it is reduced on the platinum cathode and the sensor delivers a signal. -
Page 14: Design
5 | Measurement Basics G 1610 NOTE Protective gloves must be worn when commissioning, filling and servicing the sensor. 5.1.2 Design Filling hole: If the electrode is used at high temperatures or if it has been stored without its protective flask for a longer period of time, some electrolyte will be lost due to evaporation. -
Page 15: Operating Position
G 1610 Measurement Basics | 5 NOTE The sensor evaluation is updated by the measuring device after a successfully per- formed calibration of the oxygen sensor. The nominal service life can be reduced significantly due to use. Influential factors include: - Storage / operating temperature - Contamination of the measured water - Mechanical stress of the sensor membrane... -

5 | Measurement Basics G 1610 Before screwing the membrane head on sensor body again they should be washed off, to avoid them getting in between platinum cathode and membrane. A fast occurrence shortly after first filling or an unusual high amount of them (e.g. within some days) may be a sign of air in the sensor –... -
Page 17: Environmental Pressure, Water Depth And Air Pressure
G 1610 Measurement Basics | 5 5.2.2 Environmental pressure, water depth and air pressure The environmental pressure, water depth and air pressure play an important role at the place of measurement for the following points: - Calculation of oxygen saturation in %. Clean water can achieve 100 % saturation in air. - Page 18 5 | Measurement Basics G 1610 • Filling pipette Required material: • Electrolyte KOH • Flat blade screw driver • Paper towel • Polishing foil (pink) • Suitable gloves *), Safety goggles • Wash basin • eventually spare membrane head GWOK 02 Procedure: First the membrane head is unscrewed and the old electrolyte is removed.
