A temperature controlled 1 Ω and 10 kΩ standard resistors setup has been developed at National Institute of Metrological Research, (INRIM), to transfer the traceability to high accuracy multifunction electrical instruments used in Secondary calibration laboratories. These two standards are formed respectively by ten in parallel connected 10 Ω and 100 kΩ resistors inserted into a temperature controlled aluminium box. In addition, the 10 Ω resistors are put in separate place from the 100 kΩ resistors and in oil bath. Preliminary results of short time stability (2h) were about few parts of 10–8.
