The authors designed and realized an instrument for resistance measuring using the known comparison method. As the first solution it was a single range unit for small resistors. The further investigations had a goal to reach a wide resistance range measuring. It was achieved, but some of appeared difficulties had to be overcome. The paper presents the real instrument characteristics and describes the way of practical solutions of their improvements.
