Page 21: Description
DPS400 (Mod P) Digital Pitot Static Tester Figure 4 The DPS400 Pitot Static Test Set provides an accurate and convenient method of performing leak testing of aircraft pitot-static systems including air data computers and airspeed, altimeter, mach, vertical speed, engine pressure ratio, and manifold pressure indicators. The DPS400 is a microprocessor based pitot-static tester. - Page 22 INSTRUCTION MANUAL DPS400 The DPS400 has a menu-driven, electronic control panel that simplifies the operation of the test set. Menu selectable items include: display units, programmable protection limits, and calibration/maintenance support. Protection limits are included in the test set to avoid damage to the aircraft systems or instruments to which it is connected.

- Page 24 INSTRUCTION MANUAL DPS400 STATIC VENT Releases applied static system pressure, allowing tester to return to ambient atmospheric pressure. STATIC CONTROL Controls Static system pressure to simulate the barometric conditions for altitudes between –1000 Feet and 55,000 Feet. POWER CONNECTOR Connects external power to the tester. The current Mod P, uses either a standard 115 VAC plug or a cable for operator installation of a plug.
- Page 25 The pitot and 2423F static adapters universally fit many aircraft but in some cases these adapters are not recommended or are inadequate. Barfield distributes high quality custom made pitot and static adapters for use on all general aviation, airline, helicopter and military aircraft.

Page 53: Leak Checking The Tester
This is necessary to test the leakage of the hoses as well as the tester. This is the ideal leak test to determine the condition of the tester and hoses together. If a sealing plug is not available, then leak test the DPS400 without the hoses connected. -
Page 54: Static Leak Checks
Set the POWER switch to ON. The power indicator illuminates. Wait until initialization completes (indicated when the parameter display appears). The Protection limits may be disabled during the DPS400 Leak tests to reduce the time necessary to check the condition of the test set and, because the transducers used in the test set are resistant to damage typically affecting Aneroid Instruments. - Page 55 INSTRUCTION MANUAL DPS400 To begin the Static Leak test, press the Leak Test Button ( F2 ).
