Fuel Quantity Test Set DFQ40K The DFQ40K is designed for and is compatible with all aircraft, which have AC capacitance, based Fuel Quantity Indicating Systems including those equipped with transient suppressors. The DFQ40K has the ability to measure the insulation breakdown of tank units, wiring and connectors associated with the system, capacitance of the tank units which measure the level of fuel in the tanks and simulation of capacitances required to test and calibrate the aircraft indicating system. In addition to performing the standard capacitance tests of the Tank(s) and or Compensator, the DFQ40K has an additional troubleshooting mode that will provide the user with a relative indication of a problem associated with the Phase of the return current like that provided by the Features Barfield 2548H tester. The DFQ40K measures Low Resistances, DC Voltage & Indicator Drive Current. The DFQ40K is also > Microprocessor based equipped to measure the Distance To Fault to localize > Completely self contained AC capacitance fuel problems with the HIZ coax, continuity of the Shield Monitor, quantity test system if the aircraft is so equipped, and Bonding tests to 0.001 Ohm > Measures capacitance, insulation, DC voltage, resolution. resistance and distance to fault > Capacitance simulation and indicator testing The Simulator section has been redesigned to permit direct > Custom multi-line backlit graphic display numeric entry of the desired Tank and/or Compensator > Direct keypad entry of Tank and Comp simulation capacitance to be simulated using a numeric keypad. values > Uses all existing fuel quantity cables The panel connector labeled Com Link will be used with > Uses new generation of Smart Cables to perform a new generation of Smart Cables.

With the incorporation of the BACK, NEXT, MODE and Height 14.0 35.6 RANGE pushbuttons to the panel membrane, switching the Width 12.0 30.5 overall number of different screens, such as sub-menus to be Depth 6.0 15.2 displayed, is greatly reduced. This will simplify the screens and make it easier for the operator to learn and navigate. lbs. kg This also makes it possible to remove all pre-defined Weight 10.0 4.54 FUNCTION pushbuttons and embed those functions into the Soft Function key selection scheme.
