Use to test hydraulic circuits and components for flow
and pressure capacities as recommended in the Testing
section of this chapter. This tester includes the following:
1. LOAD VALVE: A simulated working load is created
in the circuit by turning the valve to restrict flow.
2. PRESSURE GAUGE: Glycerine filled 0 to 5000 PSI
gauge to provide operating circuit pressure.
3. FLOW METER: This meter measures actual oil flow
in the operating circuit with a gauge rated from 4 to 40
GPM (20 to 150 LPM).
