3.13 Lower bottle until the level of the fuel is at the
same level as the -∆P fitting.
3.14 Remove the fitting and reattach to the ∆P+
port. Do this quickly because fuel will drip from
the open line fitting.
3.15 Raise the bottle and again allow fuel to flow
from the bottle to the air trap bringing any air
that is in the system with it. Hold the bottle up
for about a minute. Transfer at least 50 mls of
fuel. Any air in the system will flow out slowly
and can be seen as irregular drips from the
shortest drip tube. Make certain the level of the
test fuel in the bottle stays above the fitting on
the bottom of the bottle.
3.16 When air bubbles no longer emerge, turn the
FLOW CONTROL SELECTOR VALVE to
the RUN position.

3.17 Lower the bottle so that the level of the fuel is
level with the middle of the -∆P port.
3.18 Make a note of the reading on the screen for
the ∆P including its sign, if any. ∆P1 is dis-
played under "2:" and ∆P2 is displayed under
"3:". A ∆P1 of 1 mmHg and a ∆P2 of 0 mmHg
are shown here as examples.
3.19 Raise the bottle to about 400 mm above the -
∆P port (set bottle on top of JFTOT cabinet).
This will cause the ∆P reading to increase
since pressure has been added to the positive
side. Make a note of the reading on the screen
for the ∆P, including its sign, if any. The
reading will be about 25 mmHg. A ∆P1 reading
of 26 mmHg is shown here as an example.
