DC 400A Fuel Quantity Test Set

Description

The compact and lightweight DC400A is a complete fuel quantity system test set for use on aircraft that have probes with integral diode rectification, commonly called “DC” fuel quantity  systems.

The DC-400A is a completely self-contained, portable, lightweight, internal battery powered  DC fuel quantity system Test Set. The tester is specifically designed, when used with the proper Adapter Module, to meet the requirements for  testing and calibration of a wide range of Aircraft DC Fuel Quantity Systems. The Interchangeable adapter modules customize the DC400A to interface directly with a specific aircraft without  the need for an external adapter cable. The digital monitor function monitors the fuel quantity indicator/signal conditioner output directly in pounds, volts, ratio, etc., depending on  the module.

The DC400A has been engineered to provide the technician the following capabilities:

• Capability to bench check Aircraft fuel quantity system components.
• Capability to test all major components and circuitry in the Aircraft’s DC fuel quantity system.
•  Provides direct digital LCD readout of probe capacitance.
• Digital readout of quantity system output in (volts, lb., ratio, etc.).
•  Maximum ease of operation and maintenance.

Features:

• Completely self contained DC capacitance fuel quantity test system
