The portable W 434 can be adapted to applications in the automotive, aerospace, electronics and medical industry by different combinations of low voltage and/or high voltage generators up to 1,500 Vdc/1,060 Vac and a RLC measurement bridge. In case of changing test specification only a software update is needed.
