Fuel Quantity Test Set

Fuel Quantity Test Set

The DE8491EX is a microprocessor controlled test set capable of taking probe measurements and simulating fuel state conditions. The automated test procedure reduces test time and helps eliminate operator error. Test scripts are written in line with existing maintenance procedures and users can download the test data for diagnostic purposes and trend analysis.

The test set is operated via simple menu-driven software and platform-specific configuration files. Connection to the aircraft is made via application-specific cables to a multi-pin connector, allowing for multiple probes to be measured over a single connection.
