Description
COMBI421 Multifunction installation tester for tests on domestic and industrial systems with single-phase power quality analysis
COMBI421 carries out tests of electric systems in compliance with IEC/EN 61557-1 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 environmental parameters (illuminance, temperature), leakage current and the electric quantities active power, harmonics, power factor on single-phase systems and, last but not least, it 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. The instrument has been provided with the innovative AUTO function: by selecting this function and only setting the value of RCD current, COMBI421, 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.
