The VIAVI PSD60-1AF is designed to calibrate and troubleshoot any AC capacitive fuel, oil or LOX quantity system. This test set is utilised extensively by rotary and fixed-wing military aircraft operators around the world. The PSD60-1AF will: Measure the capacitance of any AC capacitive fuel, oil or LOX quantity transmitter, or sets of transmitters connected in parallel. Simulate either one or two capacitors simultaneously to calibrate any AC capacitive liquid quantity gauging system. Measure the insulation resistance in megohms of capacitive liquid quantity transmitters (probes) and/or aircraft wiring.
