In this article a recently constructed scanning electrochemical microscope with an original automatic target location facility is described and its operation is demonstrated on different targets. The measuring tip positioning device is based on stepper motor driven linear modules with 75 nm linear travel resolution. The home‐built electronic unit and the Windows 95 compatible measuring and image‐forming program furnish the microscope to operate in both amperometric and potentiometric modes. A novel, simplex algorithm based automatic target location program was developed to substitute the tedious and lengthy manual tip positioning. In this article different strategies are described and the most important results of this investigation are summarized.
