2. Turn the latch on the analytics panel to the unlocked position. Open the analytics panel.
3. Remove the lid from the KCl electrolyte reservoir. Refer to
4. Fill the reservoir (approximately 200 mL).
5. Install the lid.
6. From the front of the analytics panel, squeeze the KCl electrolyte tube with thumb and finger to
push the air bubbles up the tube to the reservoir. Refer to
When an air bubble is near the reservoir, use two hands to squeeze the tube on both sides of the
analytics panel to push the air bubble up.
7. Continue to squeeze the tube until the KCl electrolyte in the reference electrode is at the top of
