Procedure:
1. Immerse redox sensor in calibration solution.
2. Reset calibration to factory setting (if necessary).
3. Enter ORP value of the current calibration solution.
4. Confirm calibration.
Calibrating oxygen measurement
For calibrating the oxygen measurement, you can choose from the following output forms:
percentage saturation and amount of dissolved oxygen. It suffices to use one version for calibrating
the oxygen measurement.
Procedure for calibrating based on "percentage saturation [%]":
Fig. 31: Menu structure for oxygen measurement calibration based on "percentage saturation [%]"
1. Hold sensor in air saturated with water and wait until the measured value and temperature
have stabilised (~15min).
2. Reset calibration to factory setting (if necessary).
3. Enter pressure value (mbar) of the local air pressure.
4. Confirm calibration.
5. The current measured value must be 100%.
Procedure for calibrating based on "dissolved oxygen [mg/l]":
Fig. 32: Menu structure for oxygen measurement calibration based on "dissolved oxygen [%]"
1. Immerse oxygen measurement head in solution with known O2 concentration.
2. Reset calibration to factory setting (if necessary).
3. Enter O2 concentration value of calibration solution.
4. Confirm calibration.
5. Check current measured value.
