Sonel MMR 6500 Lm

The MMR-6500 digital meter is designed for measuring low resistances with a stabilized current of up to 100 A. The use of test clamps enables the safe measurement of breakers (high-, medium- and low voltage), isolators and other components earthed on both sides. The MMR-6500 series meters are equipped with a unique module in their class that measures inductive components which have a current of up to 10 A, enabling the winding resistance of motors, transformers and other inductive components to be measured. Another useful function is the temperature measurement and the automatic compensation of results with relation to the measured temperature or temperature set by the user. The system is completed with a recorder function. Special measuring algorithms and additional functions allow an appropriate measuring method to be chosen depending on the measured component and measurement conditions, thus, widening the application areas of the meter. The state-of-the-art user interface, various communication interfaces, wireless communication and communication with the computer, printer, 2D code reader are integrals features which enable full, comfortable and intuitive management of not only measurements and their results but also ID data of measured components. Key features of the instrument:

  • resistance measurement of:
    • switch and contactor contacts, HV breakers, including those earthed on both sides,
