The lengths of the links comply with the conditions: O͞₁A=1, O͞₁B=0.692, A͞B=1.5, B͞C=0.693, C͞E=0.626, C͞D=0.353, D͞E=0.442, O͞₃E=0.941, O͞₁O₃=0.692, D͞F=0.98, O͞₂F=0.892, O͞₂O₃=0.892 and O͞₁O₂=1.42. For the specified dimensions, points O₃, F and B practically coincide (they are conditionally shown as not coinciding). Closed kinematic chain O₃EDFO₂ is a five-bar linkage having two degrees of movement. Weight P is mounted on the extension of link 1. End a of link 2 serves as a hand travelling along scale N. Intermediate link 3 connects the basic mechanism to lever 4 at whose point A load Q is suspended. Weighing is performed by getting link O₂F into the horizontal position. Hand a indicates the weight Q of the load on scale N. Counterweight P is interchangeable. Each counterweight P is used with a correspondingly graduated scale. Scale N has approximately equal graduations.
