| Abstract: | A new type intelligent instrument for the measurement of conductor dc resi stance has been developed based on the principle of small current/voltage ration. The instrument can measure conductor d.c. resistance fast and accurately and can convert and display the measured value automatically to the resistance at 20°C based on 1 km conductor. Besides, the instrument features liquid crystal display of Chinese characters, battery power supply and easy field use. |
