Using 1 quart distilled water, add 1 oz bottle of A126
Fluorescein green color concentrate.
Remove a tubing connector from the manometer
and pour fluid in to mid-point level. Shake to
remove air bubbles and slide scale so zero mark
is in line with the meniscus of the two fluid
columns.
For readings in inches of mercury, fill with 13.6
sp. gr. triple distilled mercury. When used with
mercury, some discoloration of the vinyl tubing
will normally occur.
