M75L performs the measurement of the Global Earth Resistance, the measurement of the tripping time of AC residual current devices, the measurement of Insulation and Continuity of earth and equipotential conductors in accordance with the regulations in force in civil electrical installations.

To make it versatile and fully usable at any level of end user, the instrument has been inserted in the innovative AUTO function: choosing this function and setting only the value of the current of the RCD, M75L connected to a power outlet, performs in sequence global earth resistance test, test on RCD, Insulation test. At the end of the test all the results will be shown with an indication of whether or not the standard requirements are met with a simple OK or NOT OK symbol. M75L provides several additional functions such as 1-terminal phase cyclic sense measurement, leakage current measurement with optional clamp transducer and a powerful multimeter function for voltage and current measurement in true TRMS RMS value.
