Barfield 2548H Features and Specifications *
Barfield 2548H Fuel Quantity Tester is a universal test set for AC Capacitance type systems. It meets or exceeds the range, accuracy and safety requirements for fuel quantity systems up to 1000 pF and is designed to operate with guarded capacitance type systems. It is OEM accuracy and safety approved and requires no external power.
The test set can measure and simulate tank capacitance from 0.1 to 999.9 pF. It can measure insulation breakdown from 50 K to 5000 M. with an accuracy of ± 5% of nominal reading. The 2548H is a small, self-contained, battery powered, analog test set that can measure system insulation, capacitance, and simulate current to drive mA style indicators. The unit is small enough to use in confined places, but accurate enough to use as a bench tester.
The 2548H test set comes in a standard configuration and includes a two-terminal megohmmeter. The unit is also available in a guarded three-terminal megohmmeter when ordered with Option B. A standard lead package is provided with all the accessories required to adapt any aircraft fuel quantity adapter cable to the test set. This unit in conjunction with the appropriate Adapter Cable interface provides the operator with a complete fuel quantity test system.
