TRANSIT, ONE-MINUTE; AND TRANSIT TRIPODS

Organization:
GSA - FSS - Federal Supply Service
Year: 1985

Abstract: This specification covers one-minute transits and tripods for use with transits.
Transits shall be of the following classes, as specified (see 6.2):
         Class A  -  Small, lightweight; mountain or mining transits.          Class B  -  Average size and weight; engineer's and city transits.          Class C  -  Maximum size and weight; surveyor's traverse and                      triangulation transits.


Intended Use: The transits are intended for use in surveying operations. Class A covers an instrument of minimum weight, small dimensions, and compactness for use where those factors are of essential importance consistent with the required accuracy. Class B covers an instrument of medium weight and dimensions for use where transportation is not a critical problem or where circles larger than class A are desirable. Class C covers an instrument of maximum weight and dimensions for use where transportation facilities are readily available or where a higher order of refinement in determination of angular values is required.
