Conclusions
In order to ensure uniform measurements in this sphere of electrometry, it is necessary to test every electrometer both on release from production and in the course of utilization; this is only possible if the production of small-current and large-resistance standards is organized.
In order to reduce the number of electrometers rejected in testing, it is advisable to provide in their design adjustable elements suitable for eliminating in the course of testing the systematic errors due to changes in the parameters of various circuit elements during intervals between tests. Above all, this affects high-value resistors since they are the least-stable elements.
