VIAVI PSD60-1AF – AC Capacitance Fuel Quantity Test Set

The VIAVI PSD60-1AF AC Capacitance Fuel Quantity Test Set is designed to calibrate and troubleshoot any AC capacitative fuel, oil, or LOX quantity system.

The PSD60-1AF will perform the following:

• 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

NOTE: Aircraft-specific interface cables are required and must be purchased separately.

Key Features

• Solid-state circuits and LCD backlit display for low power consumption and high reliability
• Battery-powered for complete portability and ease of maintenance
• Lightweight aluminum case with a hinged compartment in the lid for test lead storage
• Small size permits testing in restricted spaces
• Push-button “extended range” switch permits readings up to 9,999 pf or 10,000 MΩ; over-range indication on LCD
• Tested and approved for use in any function with fuel in tanks; battery power eliminates the need for voltage (safety) checks
