The Castleberry Model 377-4 Tester is a compact, portable and precise pitot-static test set, complete with vacuum-pressure pump, valves, hoses, electric cord and monitoring instruments.All components are contained within the fiberglass case, 10 inches high, 15 inches wide and15 inches deep, weighing 30 pounds.
The 377-4 can be used by one technician for all test procedures right on the aircraft or on the test bench. The 377-4 produces precise and controlled pressures, pitot and static, that are normally sensed by airborne flight instruments. Through adapter fittings and hose connections, the precise pressures generated by the tester can be applied to the aircraft's normal pitot and static lines or directly to a specific instrument to check for proper operation. The 377-4 supplies both positive and negative pressure (vacuum). Self-test of the 377-4 can be made quickly and easily at any time.
Instruments used in the 377-4 are highly accurate and sensitive. These instruments are calibrated and certified to FAA Standards under controlled environmental conditions, thus providing a reliable testing standard.
