HT Instruments COMBI 419 [1003280] Multifunction Installation Tester

COMBI419 carries out tests of electric systems in compliance with CEI 64-8 and therefore measurements of overall earth resistance, tests on RCDs type A and AC up to a rated current of 1A, Insulation, Continuity and short-circuit currents, it also allows measuring and saving leakage current and offers the possibility of checking phase sequence only using one lead.

The internal memory allows saving the measurements carried out in order to subsequently transfer them onto the PC through the serial connection. In order to make it versatile and fully functional for any kind of end user, the device has been provided with the innovative AUTO function: by selecting this function and only setting the value of RCD current, COMBI 419, connected to a power outlet, carries out tests of overall earth resistance, on RCDs and insulation tests 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.
