Abstract: The invention relates to a system for determining the height of a tripod-mounted geodetic tool using a reference area. Said system comprises a spacer element (20) to be mounted on the tripod (25) and means (2) for linear measurement which are to be applied on the spacer element (20). A scale is disposed on the means (2) in such a manner as to directly indicate the height (h) of the tool (28). The means are preferably configured as a tape measure (2) or a plumb bar (1′). The invention provides a means for measuring the height of the tool outside the plumb line (32) with a sufficient amount of exactness and without substantial additional costs and/or effort.

Abstract: A lockable stand in order to be able to transport the stand. A central leg (2) is provided with a first support plate (26) and the other stand legs (3, 4) are provided with respective further support plates (36, 46) which are placed on the first support plate (26) of the central leg (2). Locking consist of pegs for locking the legs together are arranged on the support plates and coordinated holes or a strap of the central leg (2), in which the strap is fastened to a clamp fitting (25), engage one another. Locking of the legs in a retracted position is produced by means of a lock (27) arranged on the central leg (2). A manipulation of the stand by an operator can be performed in the upright position.
