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.

 

Included Accessories are:

 

  • User manual on CD-ROM and quick guide
  • ISO9000 calibration certificate
  • Carrying bag
  • CABLE WITH BANANA GREEN - BLACK - BLUE SHUKO PLUG
  • SET OF 3 CABLES, 3 ALLIGATOR CLIPS AND 3 LEADS BLACK
