E. Do this test.

ACTION	RESULT
1.Pressurize the Green hydraulic system (Ref. AMM TASK 29-10-00-863-001).
2.Examine the HP manifold and the pipe connections for leaks.	No leaks.
3.Compare the hydraulic pressure indication on the ECAM system (lower) display with the indication on the pressure gage 1072GM of the Green power accumulator.	The digital pressure indication agrees with the indication on the pressure gage 1072GM.
4.On the panel 50VU: Lift the guard and set the HYD/LEAK MEASUREMENT VALVES/G pushbutton switch (P/BSW) to OFF.	On the panel 50VU: The OFF legend of the HYD/LEAK MEASUREMENT VALVES/G P/BSW comes on. On the lower display unit (DU) of the ECAM: The flow arrow and system name of the Green system change color to amber.
5.On the panel 50VU: Set the HYD/LEAK MEASUREMENT VALVES/G P/BSW to on.	On the panel 50VU: The OFF legend of the G HYD LEAK MEASUREMENT P/BSW goes off. On the ECAM lower DU: The color of the Green system flow arrow changes to green and the color of the system name changes to white. NOTE: When you set the P/BSW to on, the ECAM lower DU can change to the ELEC page. Also the single chime audio warning and the MASTER CAUT light operate. You can ignore these indications. Cancel the MASTER CAUT light and set the HYD page on the ECAM lower DU to find the hydraulic indications.
6.Control the hydraulic supply to reduce the Green system pressure. Compare the indication of the ECAM system display with the indication on the pressure gage 1072GM.	The ECAM pressure indication agrees with the indication on the pressure gage 1072GM.
