    Introduction (Figure C1) 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.

    Pneumatic Controls (Figure C2) An AN4 connector provides the output connection. The instrument is designed to operate with 5 metres of 6mm bore pipe attached. Note: CLOSE OPEN Figure C2 - Pneumatic Controls Electrical Connections Refer to publication K0415 pages 6 and 7 for the fitting of batteries and the charging of batteries.

    Airspeed Switch Tests Select TASK, AERO: Select AIRSPEED SWITCH TEST:  If necessary, SELECT AERO UNITS:  Method (accessible switch contacts) Connect the instrument to the pitot system and connect the airspeed switch as shown: Ensure that the static system is vented to atmosphere before starting the test. Contacts must be potential free.
  • Page 13 Ensure that positive pressure is selected and close the release valve. Close the manual let-down valve. Zero the airspeed reading by pressing the ZERO key. Press the RUN key (F1) and operate the hand-pump, continue until the switch operates: Carefully open the release valve and allow airspeed to decrease until the switch operates again.
  • Page 14: Airspeed Leak Tests

    Press the RUN key (F1) and operate the hand-pump, continue until the switch operates and immediately press (F2). Carefully open the release valve and allow the airspeed to decrease until the switch operates again and immediately press (F2). The display shows the operating airspeeds and hysteresis.
  • Page 15 Set WAIT and DURATION of leak test times: When ready, press the RUN key (F2): Initially, the WAIT period counts down, followed by the timing period. The START SPEED is recorded as soon as the timing period starts. At the end of the test the display shows the complete details of the test.
