ABSTRACT:
A shift-error adjuster is incorporated into a substantially parallelogram guiding frame or flexure of a platform load cell to permit adjustment of the flexure to compensate for off-center loading of a scale incorporating the platform load cell. First and second vertically oriented end sections are interconnected by upper and lower deflection sections to form the parallelogram flexure. First and second reduced thickness bending portions are formed into the upper end of one of the end sections to define first and second axes which are perpendicular to one another. Vertically oriented adjusting screws are associated with each of the reduced thickness bending portions to effect bending of the end section about the first and second axes to thereby adjust the vertical spacing between the interconnections of that end section and the upper and lower deflection sections.
