The extra small and handy loop impedance meter MZC-304 from Sonel is used for loop measurement of ZL-PE, ZL-N and ZL-L in 230/400V networks. The test current varies between 7.6A and max. 13.3A depending on the mains voltage. A measurement of the impedance ZL-PE is also possible without triggering the RCD. Tests can be performed with test leads as well as with the handy UNI protective contact adapter. Due to extensive measuring accessories, measurements can also be carried out in 3-phase networks. Further measurements such as AC voltage, frequency or resistance of the protective conductor can be transmitted wirelessly to the PC via OR-1 adapter and evaluated.
