GENERAL INFORMATION
1.1 INTRODUCTION
This manual provides operational information for the Aeroflex PSD60-2R Fuel Quantity Gauging System Test Set.
The PSD60-2R Fuel Quantity Gauging System Test Set is an instrument that permits complete functional
checkout and calibration of an AC Fuel Gauging System, on or off the aircraft. The test set can accurately
measure the capacitance of Tank Units, Compensators, or entire systems. The test set can also simulate
capacitance values for the operation of Indicators, as well as measure the insulation resistance of Tank Units and
cabling.
The insulation resistance measurement circuit normally operates in three terminal configuration. If a direct short
is present from signal source to ground the system will display short. If a direct short is present from signal return
to ground the systems reading is undefined.
Operation of the test set is essentially automatic (no manual nulling required). To evaluate a particular system,
connect it to the applicable input. Panel controls are set to determine what is displayed on the digital display.
The test set is powered by 18 C sized alkaline batteries. The batteries may be replaced without need of test set
recalibration. Battery condition is displayed on the digital readout.
The test set is shipped with a chassis ground cable. In order to properly test a system, specific aircraft interface
cables are required but not furnished with the test set.
