The multimeter is the ideal measuring instrument to measure leakage currents. This is made possible by the extensive measuring range of the multimeter. Also, current measurements up to 150 A AC can be made with the multimeter. To test supply lines with a current of up to 150 A, the multimeter for the corresponding cable cross-section can be opened up to 30 mm. In addition to the current measurement, the multimeter can also measure voltages up to 600V directly. Because of the current and voltage measurement, the multimeter is the perfect measuring instrument to carry out measurements and analyzes on, for example, three-phase networks. For example, the continuity test can be used to find a wrong wiring in sub-distribution boxes.
