As is generally known, when the influence of the terrain relief upon the readings of gravimeters is taken into account, then the region surrounding the points of observation should be divided into several elementary sections. The vertical component of attraction of an elementary section can be expressed by an angle at which any element of the relief can be observed. This served as a basis for the construction of a gravitational clinometer, which in the absence of large scale topographic maps, makes it possible to determine regional corrections at a distance of up to 50 m from the point of observation. The use of this instrument makes the determination of corrections simpler than when leveling is applied for this purpose.
