Setup/Installation

Remove the electrode protective cap.

If the bulb is dry, soak the electrode in HI 70300 Storage Solution for at least

one hour.

Preparation of reference electrode:

1. Unwrap Para lm™ seal found

over ceramic junction on inner

stern of the reference electrode

and discard. This is only used for

shipping.

2. Rinse inner stern with deionized

water, making certain to wet o-ring

found on the inner stern.

3. Reassemble reference electrode

by gently pushing the inner

assembly into the outer body (from

the bottom), slide spring and cap

down the cable and over the top of

the inner stern. Screw the cap into

place.

4. Unscrew and remove the  ll hole

plug and o-ring on  ll hole spout.

5. Using the dropper pipette provided,

add a few drops of HI 7072  ll

solution to the electrode. Invert

electrode to wet the o-ring and rinse the electrolyte chamber.

6. Holding the body of the electrode gently press the cap with your thumb.

This permits the  ll solution to drain out of the body. Release your thumb

and verify electrode returns to its original position (you may need to

gently assist for this to occur).

7. Fill electrode body with HI 7072  ll solution until solution volume is just

below  ll hole.

Note: During measurement always operate reference electrode with the  ll

hole open.

Measurement
