After adding the beam-splitting and data-acquisition system, a set of high-accuracy ultraviolet standard radiometer (HAUSR) with self responsibility standard is constructed by using the standard detector of National Institute of Standards and Technology(NIST) as core element. The core elements of HAUSR have been tested. With the responsibility of the standard detector known, the responsibility standard of HAUSR had been deduced by theoretical derivation and adding corresponding correction factor. The accuracy (to 1.3%) of HAUSR is analyzed. It proves the HAUSR system has fine stability, high accuracy and self responsibility standard.
