A-52. To keep the connections as short as possible in order to maintain system.
A-53. A dual or double-speed synchro system.
A-54. Greater accuracy without the loss of self-synchronous operation.
A-55. The gear ratio between the two transmitters.
A-56. A tri-speed synchro system.
A-57. If one of the receivers goes bad the entire unit must be replaced.
A-58. It is used in synchro systems to prevent false synchronizations.
A-59. Electrical zero.
A-60. The voltmeter method.
A-61. A61.It ensures the synchro is on 0º, not 180º.
A-62. A TR is zeroed when electrical zero voltages exist across its stator windings at the same time its
rotor is on zero or on its mechanical reference position.
A-63. Approximately 37 volts.
A-64. Never leave the circuit energized for more than 2 minutes.
A-65. To ensure that it did not move off zero while it was being clamped.
A-66. Zero or minimum voltage.
A-67. The coarse synchro.
A-68. The electrical lock method.
A-69. It can be used only if the leads of the synchro are accessible and the rotor is free to turn.
A-70. The synchro under test is not on electrical zero.
A-71. Replace it.
A-72. Improper wiring and misalignment.
A-73. An overload indicator.
A-74. The transmitter or main bus.
A-75. 150º and 330º
A-76. Use only one receiver so as not to overload the tester.
