Abstract: This paper introduces the key technology research point of the carpet resistance testing, also the design and using effect of the test instrument. The technology principle of the carpet resistance testing is illustrated. The instrument uses the adjustable DC power supply and the constant weight column electrode with conductive rubber plate to apply voltage to the test sample. The sample and the known value standard resistance build up the Wheatstone bridge test circuit to measure the resistance value of the sample. The carpet resistance test instrument can achieve exact test results, also has good stability. It can correctly test and evaluate the resistance property of different carpet material.
