The PSDAF-KC135 Interface Unit permits complete functional checkout of the KC-135 aircraft’s fuel system. The unit can accurately measure the capacitance of Tank Units by routing all needed signals to and from the PSD90 Capacitance Tester. The test set can also simulate capacitance values for the operation of Indicators.

The PSDAF-KC135 includes all cables necessary to connect the PSD90 to the aircraft, including chassis ground cables for proper grounding to the aircraft.

Features include:

• Potted Probe Adapter Cables to connect to Tank Boundary Probe connectors that are not easily accessible (included)
• Two and three wire jumper required for TIU calibration (included)
• Shorting plugs to short the HI-Z, LO-Z, COMP and Shield paths together for measuring wiring harness resistance (included)
• Distance-To-Fault (DTF) measurement for locating a break in the shield of a coax or shielded wire
• Tank/Probe capacitance and resistance measurements from the TIU or Tank Boundary
• Simulation to the indicators from the FMAC for indicator verification or calibration
