The MPI-520 and MPI-520s are multifunction electrical meter which are used for many various operations. Both of these meters perform the diagnosis of electrical installation according to IEC 61557 standards.
Digital meter MPI-520S is designed to measure the impedance of a short circuit loop also without triggering RCD, parameters of RCD, insulation resistance, earthing resistance, continuity and also for phase sequence testing. Furthermore to measure and logging of AC voltage and current, frequency and power.
Wide range of standard accessories enables to perform all necessary measurements and safety test. Highly professional portable multifunction electrical meter with a memory of measured parameters.
