Barfield 101-00802 Adapter Module for DC400A Fuel Quantity Test Set

The Barfield 101-00802 Adapter Module serves as an interface between the DC400A Fuel Quantity Test Set and various aircraft fuel quantity systems. It enables proper electrical connection and signal adaptation for accurate testing of aircraft fuel gauges, probes, and indicators. This ensures precise calibration and troubleshooting of the entire fuel quantity measurement system.

The 101-00802 Adapter Module connects directly to the DC400A Fuel Quantity Test Set via its dedicated interface ports. It translates the output signals between the tester and the aircraft’s fuel quantity circuitry, allowing the test set to simulate fuel conditions and verify system accuracy. The module ensures that measurements remain stable and traceable during test procedures.

No. The 101-00802 is only necessary for aircraft whose fuel systems require specific adapter interfaces to match their capacitance or resistance-based circuitry. For other aircraft configurations, different Barfield adapter modules or cables may be needed to ensure compatibility with the DC400A system.

The 101-00802 is primarily designed for the DC400A and DC400 fuel quantity test sets, offering backward compatibility within that series. However, it is not compatible with older analog Barfield test systems such as the DFQ40K or AC2K models, which require separate adapter configurations.

Depending on the aircraft, additional adapter cables such as the 101-00817 (1900 Adapter Cable) or 101-00827 (Probes Adapter Cable) may be required. These accessories extend the functionality of the 101-00802, allowing it to interface with specific sensors, probes, or tank configurations.

The adapter module itself does not require calibration; however, it should be visually inspected periodically for signs of wear, corrosion, or damage to the connectors. Proper storage and handling are key to maintaining reliable electrical connections. Any physical damage or signal irregularities during testing should prompt an inspection by a qualified technician.

Store the adapter module in a clean, dry environment to protect its connectors and circuitry from corrosion or debris. Barfield recommends keeping it in its original protective case and avoiding exposure to extreme temperatures or moisture to prolong service life.

Yes. The 101-00802 Adapter Module supports both analog and digital fuel quantity systems when used with the DC400A test set. Its design accommodates various signal types, allowing technicians to accurately verify capacitance, resistance, and voltage outputs in modern aircraft fuel measurement systems.

Absolutely! Many aviation maintenance training programs use the 101-00802 Adapter Module in conjunction with the DC400A to demonstrate fuel quantity testing techniques. Its straightforward design and reliable performance make it a valuable instructional tool for technicians learning aircraft fuel system diagnostics.

Constructed with durable materials and precision connectors, the adapter module is built to withstand the rigors of daily aviation maintenance. Its compact, portable form factor makes it ideal for use both in hangars and on flight lines where mobility and reliability are essential.

Before use, verify that the module and test cables are free from debris, corrosion, or loose fittings. Ensure the DC400A test set is powered off during connection to prevent signal interference or static discharge. Following Barfield’s connection procedures ensures safe and accurate testing, protecting sensitive aircraft components.

Replacement 101-00802 adapter modules and related accessories, such as probe and tank adapter cables, are available through authorized distributors like PJi. Barfield’s global service network and certified partners also provide support, repair, and verification services to maintain test accuracy.
