IC VOL 2 - Synchros and Wind Indicating

A synchro transmitter, CX or TX, is zeroed if electrical zero voltages exist when the device whose position the CX or TX transmits is set to which position?

What are used primarily for the rapid and accurate transmission of information between equipment and stations?

What is the most accurate method of zeroing a synchro?

If synchros are to work together properly in a system, they must be correctly connected and aligned in respect to each other and to the other devices with which they are used. What is the reference point for alignment of all synchro units?

How many conditions must exist for a control transformer (CT) to be on electrical zero?

The common electrical zero position of a TX-TR synchro system can be checked with what?

Many synchro units are marked in such a manner that the coarse setting may be approximated physically by aligning how many marks on the synchro?

How many basic rules are applied when maintaining synchros?

Synchro signal amplifiers must meet some or all of how many different operational requirements?

What is perhaps the fastest method of zeroing synchros?
