A ruler for measuring angles between an oriented axis and a vector, in which calibrations of the field of angles of radii, consist of partial representation of the radii corresponding to size of the angle adopted for each field of angles, but only within those zones or areas within which such partial representation of the field of angles of radii is possible, such that every radius is partially represented in at least one zone or area. In the UPPER zone defined by a LONGITUDINAL LINE and two INTERIOR ZONAL lines, only those radii originating from a LOWER CENTRE and bounded by two FRONTIER RADII may be partially represented. In the LOWER zone only those radii originating from an UPPER CENTRE and bounded by its two FRONTIER RADII may be partially represented in the two LOWER zones defined by the LONGITUDINAL LINE and the two ZONAL lines on the same side, only those radii originating from the LOWER CENTRE and possessing the angular possibility of appearing in these zones or areas may be partially represented. In the two UPPER / LOWER zones only those radii originating from the UPPER / LOWER CENTRE and possessing the possibility of appearing in them may be partially represented, and in the two remaining UPPER / LOWER zones or areas of the device, all those radii originating from the LOWER / UPPER CENTRE and possessing such possibility may be partially represented, and in the remaining two LOWER / UPPER zones, all those radii originating from the UPPER / LOWER CENTRE and possessing such possibility. |
