This specification describes the requirements
for the murement of ' a synchro transmitter test set,LD 482753 and Drawing 1583207, capable of replacing and simulating the functions of the course gyro of Torpedo Mk 37 Type in system tests performed on the torpedo. The synchro transmitter is required to simulate any given angular position of the course gyro spin axIsrelative to the torpedo-longitudinal axis and to present on the concentric dial assembly a precise indication of this angular position in degrees and minutes. The test set front panel also presents an indication of the course gyro caged condition.
