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. CAUTION: Take care to align pins carefully. Bent or broken
pins will cause the meter to malfunction.
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
a degradation in performance or failure. When cleaning the probe, do not
scratch or damage the platinized electrode surfaces.
