The controller is now calibrated and ready for use.
To ensure a trouble-free use, the unit should be recalibrated every 4 weeks. Measuring and
controlling with a pH-controller is only as exact as the calibration. The electrode shall be emerged
into water only that the top part remains dry. Best is using the Aqua Medic electrode holder.
4. Controlling
Adjusting the set point:
- Turn knob 3 to „set“.
- Adjust knob 6 (set point adjustion) to the desired set value.
- Turn switch 3 back to „pH“.
The unit is now ready for use. As soon as the actual pH value rises or falls below the adjusted
value, the socket (8) is activated.
5. Troubles
- The unit shows wrong values on the display:
Recalibrate the electrode.
- The electrode cannot be recalibrated:
Check electrode for breakage (diaphragma), glass electrodes for glass breakage and the
electrolyte level of refillable electrodes. Take the operation manual of the corresponding
electrodes into consideration.
If the electrode cannot be recalibrated, it has to be renewed. pH-electrodes have only a limited life
span, depending on kind of use between 1 and 3 years.
