1. Introduction
This 2 bar absolute (59 inHg absolute) version of the DPI 610 provides manual generation of
pressure and vacuum for testing of aircraft Pitot and Static systems. It has a special pneumatic
manifold and output port assembly, the regulated output of the hand-pump prevents
overpressure/vacuum of the aircraft’s Pitot and Static systems.
The generated pressure or vacuum vents to atmosphere through the vent port, the user controls
the vent rate to protect the aircraft’s systems and instruments using the release valve.
A manual let-down valve, fitted directly in the output port, allows the system to be manually vented
(returned to ground level) by the user when the pressure or vacuum has vented to a safe
operational level i.e. < 1500 ft. The aeronautical option (AERO) can be accessed only from the
