In this work, an automated system capable of biasing electrostatic probes in cold plasmas and acquiring the associated data is implemented. The step-by-step design, fabrication, and fine calibration of the entire system are presented. High resolution and accuracy, increased acquisition rate and high noise rejection, are the main claims for the system presented hereby. The device efficiency is eventually demonstrated through measurements in the negative ion H- source "Prometheus I".
