With the Electrical Tester it is possible to measure leakage currents up to a range of 100 A. The Electrical Tester can measure leakage currents which appear when current flows through electrical conductors which are not designed for conduction current. The Electrical Tester can detect leakage currents and show them on the display. With the help of the Electrical Tester you can detect insulation failures in places where machines cannot be disconnected, however insulation must be checked, as for instance according to the VDE 701/702 standard. The Electrical Tester measures current flow, voltage up to 600 V, resistance and continuity. The Electrical Tester is the ideal instrument for electricians according to the VDE standard. The Electrical Tester has a compact design which allows to be placed in any pocket. The rubber protection protects the instrument against falls, so it is the ideal instrument to be used in electrical inspections and in workshops.
