Query: 1 {\Omega}-10 k{\Omega} high precision transportable setup to calibrate
  multifunction electrical instruments   A temperature controlled 1 {\Omega}-10 k{\Omega} standard Resistors
transportable setup was developed at National Institute of Metrological
Research, (INRIM) for the calibration and adjustment of multifunction
electrical instruments. The two Standards consist respectively of two 10
{\Omega} and 100 k{\Omega} parallel connected resistors nets inserted in a
temperature controlled aluminium box. Novelty of the realization is the oil
insertion of the 1 {\Omega} net with its internal connectors lowering the
thermo-electromotive forces (emfs) effects. Short and mid-term stabilities of
the setup Standards resulted on the order and in some cases better than other
top level 1 {\Omega} and 10 k{\Omega} commercial Standards. The transport
effect turning off the setup temperature control did not cause appreciable
measurement deviations on the two Standards. The Standards uncertainties meet
those requested by DMMs and MFCs manufacturers to calibrate and adjust these
instruments. A test to adjust a multifunction calibrator gave satisfactory
results.
