The paper presents the real instrument functional characteristics and
describes the way of practical solutions of its performance improvement. It
presents the design process of the instrument made for resistance measuring.
In order to achieve desired objectives, a great number of experiments have
been carried out during the development. Basically, the comparison method
has been applied. At first, it was intended for the small resistor measuring
as a single range unit. Later, the device has been improved and upgraded for
a wide range resistance measuring. Finally, some of the difficulties have
been detected and explained as well. The paper contains solutions developed
and applied for their overcoming.
