Title:Synchros
Issuing Committee:A-4 Aircraft Instruments Committee
Scope:In order to ease the equipment design engineer's problem and at the same time provide a basis for comparing measurements by manufacturer and user this recommended practice sets up standard test procedures for acceptance testing. These conditions and the basic tests to which the characteristics refer are grouped in Section 2 and compose a complete list of defining characteristics of the synchro. Specifications written around synchros have specified certain necessary characteristics for production acceptance testing, such as null voltage and accuracy, under test conditions and techniques that are mainly and properly concerned with accuracy and the shortest possible test time. These characteristics are inherently degraded when the synchro is operating for a period of time at other than room temperature. In synchros this degradation is a factor of high importance
