44.
Open shutoff valve (8).
45.
Close valve (14).
46.
Apply pressure to port (13) until pencil line on
cylinder (11) aligns with housing (15).
47.
Check voltmeter (18) readings. Voltmeter shall
read 0 to 0.10 volt rms.
48.
Close shutoff valve (8).
49.
Open valve (14).
50.
Open valve (7) and apply pressure to return port
(2) until cylinder (11) is 2.5 inches from housing
(15).
51.
Close shutoff valve (7).
52.
Check reservoir (9) fluid level. Fluid level shall
not change.
53.
Check reading on voltmeter (18). Voltmeter shall
read 2.026 to 2.106 volts rms.
54.
Open shutoff valve (8) to reduce pressure at
return port (2) to 0 psi.
55.
Disconnect voltmeter (18) and signal generator
(16) from transducer receptacle (17).
STATIC PRESSURE TEST
56.
Remove 0 to 200 psi gage (21).
57.
Connect 0 to 30 psi gage (22) between valve
(7) and return port (2).
58.
Close valve (8).
59.
Open valve (7) to apply 5 to 20 psi pressure to
return port (2) until reservoir (9) is full. Open
shutoff valve (10) and hold bleed relief valve (6)
open until reservoir is free of air.
60.
Close shutoff valve (7).
61.
Open shutoff valve (8) and allow reservoir (9) to
empty. When green strip in cylinder (11) starts
to enter housing (15), read static pressure on
pressure gage (22). Static pressure shall be at
least 2 psi.
