COMBI421 Multifunction Tester

17th Edition Multifunction Installation with 1-Ph Power Quality Analyzer

COMBI420 tests to all local regulations (17th edition) and provides test results for complete documentation. It measures overall earth resistance, tests on RCDs type A and AC up to a rated current of 1A, Insulation up to 1000V, Continuity with 200mA 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.Last but not least, it offers the possibility of checking phase sequence only using one lead.

Features :

•  AUTO test (Non-trip ground resistance, RCD, Insulation) in sequence
•  Insulation with voltage 50, 100, 250, 500, 1000VDC
•  Continuity of protective conductors with 200mA
•  Tripping time and current of RCDs type B, A, AC Standard, Selective and Delayed up to 1A
•  Loop/Line impedance, Phase-Phase, Phase-Neutral, Phase-PE
•  Loop/Line impedance Phase-Phase, Phase-Neutral, Phase-PE with high resolution (0.1mΩ)
•  Power Factor in Single-Phase systems
•  Active Power & harmonics
