measurement technology. SUBSTANCE: instrument resistor that may be used to produce resistance standards or instrument shunts has current and potential leads joined with resistive section provided with regions for adjusting resistor to higher values; cross-sectional area of current leads is greater than that of resistive section; additional regions are formed between respective adjacent potential and current leads for adjusting instrument resistor to lower values. In this way resistor value can be adjusted between permissible positive and negative limits. EFFECT: provision for correcting operator s errors in selecting resistor value. 2 dwg
