2 mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
Electrical multifunction network analyzer for LOOP, PSC & Earth Test PE-425 incorporates a built-in Earth Tester and Loop/PSC tester for ranges from 0,3 to 2000 Ohms.
Makes the insulation test at rated voltage into a 1 mA load, with user-selectable ranges for resistance and insulation resistance.
Precision measurement instrument to measure leakage currents with double operation mode: Low frequency (50/60 Hz) or wide frequency (up to 1 kHz).
