Barfield DFQ40K Fuel Quantity Test Set
The Barfield DFQ40K is a fuel quantity test set for aircraft with AC capacitance-based fuel quantity indicating systems, including systems with transient suppressors. It measures the insulation breakdown and the capacitance of tank units and simulates capacitances to test and calibrate the aircraft indicating system [1]. Avionics and electrical technicians use it with aircraft-specific interface harnesses.
