An apparatus for setting a level plane includes a spirit level having a parallelepiped shaped housing with a measuring base and a leveling plate with an upper plate surface on which the base of the housing of the level is disposed. The upper plate of the leveling plate may be tilt orientation adjusted with respect to a lower plate that is spaced away from the upper plate by adjustment screws between the upper and lower plates. The upper plate includes a ferromagnetic material and a pivot pin projecting up from it. The spirit level housing has a hole in which the pivot pin is disposed enabling the housing to be pivoted around the surface of upper plate. A retaining magnet in the housing in the region of the measuring base holds the housing to the upper plate. Alternatively, the spirit level housing has the ferromagnetic material while the magnet is in the upper plate. Alternatively, also, the housing includes the pin while the hole is in the upper plate. Pivot the housing to an orientation whose level is to be set and then adjust the adjusting screws for obtaining a horizontal setting. Doing this at several pivot orientations enables the upper surface of the upper plate to be set horizontal using the level.

An apparatus for setting a horizontal plane, comprising a leveling apparatus which indicates when it is level, the leveling apparatus having a housing and the housing having a measuring base; a leveling plate for receiving the measuring base of the housing of the leveling apparatus; the leveling plate including an upper plate having a planar surface on which the measuring base of the housing is movably disposed, the planar surface being substantially precisely planar so that the measuring base of the leveling apparatus being in direct contact therewith, thereby to provide exacting measurements; tilt adjustment means for adjusting the tilt orientation of the upper plate of the leveling plate and for thereby adjusting the tilt orientation of the measuring base of the housing on the upper plate to a selected level setting; cooperating pivot means at the upper plate and at the housing for enabling the housing to be pivoted to various orientations around the upper plate by pivoting around the pivot means; respective magnet means at the upper plate and in the housing generally at the measuring base for attracting the housing and its measuring base to rest on the planar surface of the upper plate in any selected pivot orientation of the housing around the planar surface of the upper plate.
