5. Insert electrode in buffer solution pH 4. After stabilization of the measured value, set the
display to pH 4 (No. 3).
6. Clean the probe with distilled water and put it into the buffer solution pH 7 again. Wait until the
pH value is stable. If pH 7 is not reached, repeat the calibration procedure several times.
The unit is ready for use after successful calibration.
To ensure a trouble-free use, the unit should be recalibrated and the probe be cleaned at least
every 4 weeks. Measuring with a pH-controller is only as exact as the calibration. The electrode
shall be emerged into water at most that the top part remains dry. Best is using the Aqua Medic
electrode holder.
The unit must be protected against moisture, splash or condensation water.
