59.7. Turn SAS 1 valve control (34) to EXTEND until
DVM (58) indicates 1.00 volt. SAS 1 NULL
METER (60.1) must move to the right, indicating
10 ±2 microamp. If null meter reads to the left,
SAS 1 is out-of-phase.
NOTE
If null meter moves to the left, check
extensible link wire connections (Task
7-88.1, step 7). If connector is wired
correctly, replace No. 1 self LVDT
(Task 7-88.1).
59.8. Set SAS 1 LINK TEST switch (38) to CROSS
FDBK. DVM (58) must indicate 0.50 ±0.03
volt. If null meter moves to the left, the ILCA is
out-of-phase.
NOTE
If null meter moves to the left, check
extensible link wire connections of
the cross feedback transducer. If
connector is wired correctly, replace
cross feedback transducer (Task
7-88).
59.9. Set SAS 1 FEEDBACK SELECT switch (32) to
CROSS. NULL METER (60.1) must decrease to
5 ±1 microamp. If null meter moves to the left,
the ILCA is out-of-phase.
NOTE
If null meter moves to the left, check
extensible link wire connections of the
No. 1 cross feedback transducer. If
connector is wired correctly, replace
cross feedback transducer. (Task
7-88).
59.10. Set SAS 1 FEEDBACK SELECT switch (32) to
SELF.
59.11. Set SAS 1 LINK TEST switch (38) to SELF.
59.12. Turn SAS 1 VALVE CONTROL (34) to RETRACT
until DVM (58) indicates 1.00 volt. SAS 1 NULL
METER (60.1) must move to the left, indicating
10 ±2 microamp.
NOTE
If null meter moves to the right, check
extensible link wire connections (Task
7-88.1, step 7). If connector is wired
correctly, replace self LVDT (Task
7-88.1).
