D. Move the tip back to, and past, the first leak spot noted.
When the IR-1 indicates a second change, note that spot
on the line. The leak will be near the midpoint of the two
noted change spots.
NOTE: If the tip is held at a detected leak for more than five
seconds, the IR-1 will not detect a change.
E. The IR-1 is sensitive and can take up to 30 seconds to
clear after detecting a small amount of contaminate.
Typically, it will clear in 2 to 15 seconds.
