COMBI519 | Multifunction


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.
