Measurement
Measuring by means of the direct current measuring
method (test socket); measuring the protective
conductor current for devices of Class I; measuring the
leakage current, contact current, leakage currents of
applied parts for ME devices (patient leakage current);
protection classes I to II
Measuring range: 0.020 ... 25.000 mA
Resolution: 0.001 mA
