Interconnect Systems in partnership with the designers and suppliers, Ultra-Electrics, offers a range of Ground Support Test Equipment for today’s complex Aircraft systems. They provide innovative solutions for the testing of Wiring, Fuel Systems, EMC Compliance and Digital Avionics.
Ultra-Electrics will also undertake the design and supply of special to type test equipment, to meet a customer’s specific requirement.
Fuel Quantity Test Set

This test set is unique in that it is a microprocessor controlled fuel quantity test set
It takes measurements and calculates pass/fail limits automatically, and so eliminates operator error.
The test set is operated via a simple menu-driven aircraft publication (AP) software and reduces test time by around 50%, compared to manually driven testers.
Technical Description
- One test set for all aircraft types
- No need to defuel aircraft
- Automatic operation
- Aircraft specific menu driven software
- Fuel quantity and electrical resistance measurements
- Capacitance simulation for fuel system calibration
- Tank unit simulation
- Measures fuel, Lox and water systems
- Results can be downloaded for trend analysis
MIL-STD-1553 Databus Cable Tester

The kit includes a S2476N databus network/harness tester, aircraft-specific interconnect leads to connect the tester to the aircraft of choice, consumable spares for the tester, a databus repair kit, full technical publications and a transit case.
Additional options include a calibration kit and an ARINC 429 protocol tester. The databus network/harness tester isolates all common wiring faults (short circuits, shorts to shield, open circuits and cross-overs etc.) on any platform with a 1553 databus harness system. It measures insertion loss between any two stubs in dBs.
Benefits
- Preventative maintenance using ‘busmapping’
- Reduces ‘black box’ No Fault Found rates
- Isolates all common wiring faults
- No need to disconnect main bus
- The tester can be used on any MIL-STD-1553 platform
- Removable transmitter for remote testing
- One-man operation
- Lightweight and portable
- CE Marked
It is simple to operate, with no need to disconnect the main bus and comes with an integral battery charger. Lightweight and ruggedized, it is ideal for one-man operation.
The S2476N is also the only tester on the market that can footprint a 1553 data bus, allowing users to monitor system integrity and schedule preventative maintenance.
Technical Description
- Simple to use
- Lightweight and portable
- Battery powered with integral battery charger
- Simple daily calibration
- No disconnection of main bus required
- Fault detection and isolation
- Battery low indication
- Removable transmitter for remote testing
- Insertion loss between any two stubs given in dBs
- One man operation
