Electrode Preparation

HI 4002
1. Remove protective cover from sensor tip.
2. Prepare reference electrode by filling outer electrolyte

reservoir with HI 7072.

3. Place sensor and reference electrodes into electrode

holder and connect cable connectors to meter.

HI 4102
1. Unwrap plastic film seal found over ceramic junction

on inner stem and discard. This is only used for ship-
ping and long term storage.

2. Rinse inner stem with deionized water making certain

to wet the o-ring found on the inner stem.

3. Reassemble electrode by gently pushing the inner

assembly into the outer body, sliding spring down
cable, and screwing cap into place.

4. Remove fill hole cover and o-ring on fill hole spout.
5. Using the dropper pipette provided, add a few drops

HI 7072 fill solution to the electrode, wetting the o-
ring and rinsing out the fill solution chamber.
