A TEMPERATURE VARIABLE HIGH ACCURACY 10 kΩ RESISTOR
Abstract
A temperature variable high accuracy (TVHA) 10 kΩ resistor has been developed at National Institute of Metrological Research, (INRIM), in order to transfer the traceability to high accuracy multifunction instruments used in the accredited calibration laboratories. The TVHA consists of ten 100 kΩ nominal value resistors inserted in a copper block and connected in parallel configuration. The thermal stability of the copper block is obtained with a temperature controller. In this paper we reported details of the development of the TVHA and on its thermal behaviour. From preliminary results its relative short time stability (2 h) resulted on the order of few parts of 10<sup>-8</sup>.
