2. Gently rock the electrode from side to side, pulling it away from the meter
until it disconnects.
3. Align the positioning “keys” of the replacement electrode and the main body
housing. Carefully push the electrode into the meter socket until it is fully
seated. CAUTION: Take care to align pins carefully. Bent or broken pins will
cause the meter to malfunction.
4. Tighten the electrode retaining collar until the electrode is firmly sealed to
the meter.
Replacing the Membrane Cap Assembly
The pH of the electrode filling solution in polargraphic dissolved oxygen meters
changes with time resulting in less accurate results. It is recommended that
the membrane and electrode filling solution be changed every 2 - 4 weeks
depending on usage. Because of the configuration of the membrane and
electrode, the membrane is stretched by the cathode and cannot be reused. It
must be replaced. See page 6.
Electrode Storage
Store the TRACER with the Electrode Storage Cap in place. The sponge in the
cap should always be moist without excess liquid.
Electrode Cleaning Recommendations
Contaminant Cleaning Solution

household detergent
Clean with mild detergent solution.
Rinse thoroughly with DI water.
NOTE: Do not contact the membrane with the cleaning solution. Install a new
membrane after cleaning the electrode.
