The Model PSD 60-1AF AC Field Calibration Unit is a state-of-the-art test set designed to test capacitance-type liquid gauging systems and their line replaceable unit components.

This test set can be used whenever a capacitance measurement, capacitance substitution, or insulation measurement is required. The PSD60-1AF is approved by the U.S. Military.

When using with a capacitance-type fuel gauging system, this test set performs four basic functions:

• Measure capacitance values of individual or sets of tank units (a trade term for sensor/transmitters) and/or fuel gauging circuits.
• Insert appropriate capacitance values of a fuel gauge circuit to allow functional check of calibration.
• Introduce adequate capacitance to simulate the function of the compensator.
• Measure insulation resistance of tank units and cabling.
