IFR Aeroflex PSD60-2R Fuel Quantity Test Set

The IFR Aeroflex PSD60-2R Fuel Quantity Test Set is a portable, battery-powered instrument for testing and calibrating aircraft AC capacitance fuel quantity indication systems. It performs on-aircraft or bench testing with precise measurement and simulation of capacitance values, resistance across eight ranges, and distance-to-fault diagnostics. The unit measures total tank capacitance, individual tank units, and compensators while simulating capacitance for indicator calibration and dry calibration procedures.
