Danger: Turn off the air pump prior to removing the reference electrode
filling solution bottle. If the air pump is left on, it will spatter filling
solution as the bottle is removed.
1. Unpack the reference electrode (Cat. No. 100057) and its instruction
sheet from the shipping box.
2. Carefully remove the protective caps from the bottom and sidearm of
the reference electrode. Save the caps for future storage of the electrode.
3. Shake out as much of the filling solution as possible through the
sidearm. Drain the fill solution through the sidearm or use a pipet
or syringe.
4. While passing the 1/8 inch tubing into electrode sidearm, slide the 1/4
inch tubing over the sidearm. The outside tubing should extend 3/8 to
1/2 inches over sidearm. Refer to Figure II-9.

5. Remove the cap and fluid seal from reference electrode fill solution
bottle (Cat. No. 100057F4). Hold the bottle in an upright position.
Check that the rubber gasket is properly aligned, and then connect
the cap end of the tubing assembly to the bottle. The 1/8 inch tubing
should extend into the bottle.
6. Hold the reservoir bottle above the electrode with the bottle cap end
down. The electrode should be horizontal with the sidearm pointing
up. Gently shake the electrode to allow any trapped air bubbles to rise
into the bottle as the electrode fills with solution.
