Surveying and leveling device

摘要

A surveying and measuring device and method of using the same is provided. The device, which is particularly suited for determining or measuring a rotational position of an object, comprises an elongate rigid member extending radially away from a known center of an object. Distal ends of the rigid member downwardly project points which may be compared to, for example, survey markers or known points.

主权项

1. A device for measuring and adjusting the position of a lighting element comprising:
a frame member for mounting on an upper portion of said lighting element, said frame member comprising two female socket members for receiving first and second upwardly projecting portions of said lighting element and temporarily securing said frame member and said lighting element to each other, and the frame member comprising at least one upwardly projecting member for receiving a first horizontally extending member; said first horizontally extending member comprising an elongate substantially rigid member having a first end and a second end, said first end and said second end comprising vertically downward extending members for indicating a rotational position of said frame member about a vertical axis; said frame member comprising a first level for indicating the position of said frame member relative to a first horizontal axis, and a second level for indicating the position of said frame member relative to a second horizontal axis; an aperture provided in a second horizontally extending of the frame member for visually aligning a midpoint of said frame member with a center of said lighting element; and wherein said device is selectively detachable with said lighting element and adapted to indicate a preferred translational and rotational position of said lighting element.
