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. Limit protection is provided by
computer actuated solenoid valves. The valve(s) are actuated to isolate the system under test
from excessive vacuum or pressure being applied. The limit protection trip points are user or
operator programmed using the display’s menu system. These trip points provide protection
for altitude, airspeed, rate of climb/decent and mach.
Separate internal pumps are provided to supply vacuum and pressure capable of achieving
55,000 ft and 6000 ft/min on a wide body aircraft. The test set readout and control circuits are
powered from 115/230 VAC 50-400 Hz.
