ANSWERS TO QUESTIONS Q1. THROUGH Q76.

1-78 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.
