Pressure Monitor Mode. Actual pressure and leakage rate per minute are displayed ( Figure

is pressed a second time to initiate a Vent Cycle in which the' system vents to atmosphere at
a rate of 47 mbar/minute for Pitot or 56 mbar/rnlnute for Static. As with the START key
(paragraph 5.M.), it is possible to use the STOP key to select a faster vent rate of 114
mbar/minute or 136 mbar/minute, respectively. While the system is venting, the screen
displays the pressure remaining in the system (
Figure 13
). When the system has vented, the
screen will display the caption 'SYSTEM VENTED' and the VENTED flag appears.
