5-22. INJECTOR TEST STAND CALIBRATION (Contd)
b. Test Stand Calibration
1.
Adjust regulator knob (5) on injector test stand by turning until pressure gauge (1) reads 120 psi
(827 kPa). Ensure pressure is maintained at 120 psi (827 kPa) during calibration.
2.
Press red flow start switch (3) in and out until counter (4) reads 1,020 count strokes.
3.
Look directly into vial (2) and observe reading.
NOTE
Reading of 132 counterclockwise at 120 psi (827 kPa) indicates
test stand is in calibration. If reading is more than 132 cc, the test
stand is not set up properly. Repeat setup steps. If reading is
below 132 cc, continue.
4.
Reset counter (4) on injector test stand to zero (task a., steps 16 and 17).
5.
Set counter (4) up seven strokes for each cc less than 132 cc.
6.
Dump fuel from vial (2).
NOTE
If counter is set beyond 1,050 strokes to obtain 132 cc, the test
stand is not set up properly. Repeat setup steps. If counter reads
1,050 or below, the test stand is in calibration.
7.
Press red flow start switch (3) in and out until counter (4) sets strokes to obtain 132 cc.
8.
Place motor switch (6) in STOP position.
9.
Remove test stand fuel drain connector (14) from adapter (15).
