Electrical safety tester COMBI series

insulationcontinuityinsulation resistance and continuity

Advanced multifunction installation tester for verification of electric safety of private and industrial electric systems COMBI519 carries out tests on electric systems in compliance with IEC/EN 61557-1 and therefore measurements of continuity of the protection cable, insulation resistance (with calculation of PI and DAR), overall earth resistance, RCDs type B, A and AC tripping time and current, line / fault impedance with calculation of prospective short circuit / fault current, phase sequence and conformity. The instrument is provided with the innovative AUTO function: by selecting this function and only setting the value of RCD current, COMBI519 carries out tests of overall earth resistance, RCD tripping time and insulation resistance in a sequence. At the end of the test, the device shows all results with the indication of compliance or non-compliance with the standards with simple symbols OK or NOT OK. The internal memory allows saving the measures and subsequently transfer them onto the PC through the optical/USB connection.
