Abstract
A control for a device of the type comprising at least one electronic measuring head supported by a structure composed of several elements that are capable of being displaced along the three axes X, Y and Z driven by means of electric motors 12 to 14 having a speed regulator and a control means for supply circuits 12a to 14a of the above motors. According to the invention, the manual control comprises at least one control assembly 20 mounted on an element of the structure and having a single lever for actuating a harness that detects the displacements of said lever by use of sensors 30 to 37 mounted thereon and convert the displacement into voltages a, b, c and d. The manual control being associated with a calculator that algebraically processes voltages a, b, c and d according to the three following formulas:
