Electrode Preparation

Electrode Preparation for Refillable Electrodes

1.Remove the protective shipping cap from the sensing element and save the cap for storage.

2.Clean any salt deposits from the exterior of the electrode by rinsing with distilled water.

3.Uncover the filling hole by removing the tape and then add electrode filling solution, Cat. No. 900011, to the electrode. To maintain an adequate flow rate, the level of filling solution must always be above the reference junction and at least one inch above the sample level. The filling hole should be open whenever the electrode is in use.

4.For Sure-Flow electrode only, wet the junction by pressing down on the electrode cap to let a few drops of the filling solution flow out of the electrode and then replenish any lost solution.

5.Shake the electrode downward (similar to a clinical thermometer) to remove air bubbles.

6.Connect the electrode to the meter.

Note: The fill hole must be open when the electrode is in use.

Electrode Preparation for Gel-Filled Electrodes

1.Remove the protective shipping cap from the sensing element and save the cap for storage.

2.Clean any salt deposits from the exterior of the electrode by rinsing with distilled water.

3.Shake the electrode downward (similar to a clinical thermometer) to remove air bubbles.

4.Connect the electrode to the meter.
