The Rx value gives information about the oxidation/reduction potential and is used to determine the water sterilization capacity. The setpoint is the
minimum Rx value for activation/deactivation of the titanium cell. Adjusting the ideal Rx level (setpoint) is the last step in the system set-up. Follow these
steps to determine the ideal Rx levels for your pool:
1. Connect your pool filtration system (the salt in the pool must be completely dissolved).
2. Add chlorine to the water until a level of 1-1.5 ppm is reached (approx. 1-1.5 g/m
3. After 30 minutes take a reading of the free chlorine level in the pool (manual test kit DPD1). If the free chlorine level is in the range 0.8 – 1.0 ppm,
look at the value on the Rx display and put this value into the memory as the setpoint to activate/deactivate the electrolysis/hydrolysis cell.
4. The next day check the levels of free chlorine (manual test kit DPD1) and Rx. Raise/lower setpoint if necessary.
5. Remember to check the Rx setpoint every 2-3 months and/or when the water parameters change (pH/temperature/conductivity).

6.10 Calibration with buffer (buffer
solution 465 mV): Follow the 4-step
instructions that are shown on the
display.
6.12 Manual calibration: Allows
adjustment of the probes to
1 objective measurement (without
buffers) – only recommended for
correction of small deviations in the
readings.
