REPLACING THE ELECTRODE
1. Unscrew and remove the electrode collar. Turn collar counter-
clockwise.
2. Gently rock the electrode side to side, while pulling it away from the
meter, until it disconnects from the electrode socket.
3. To attach an electrode, align the slots and carefully plug the
electrode into the meter socket.
4. Firmly tighten the electrode collar to create a seal with the rubber
gasket between the electrode and the meter.
Electrode Cleaning Recommendations
Do not soak the electrode in the solutions for longer than the
recommended length of time. To do so may cause a reference potential
shift which will cause degradation in performance or failure. When
cleaning the electrode, take care not to scratch or damage the sensing
surface or the platinized electrode surfaces.
