This instrument has a constant current circuit, and drives leakage currents (I) between LINE-NEUTRAL as illustrated in Fig.5 to activate RCDs, moreover, can output and measure leakage currents flowing to
the earth as shown in Fig.6.
Influence of the fluctuations in system voltages is less on this instrument due to the incorporated constant current circuit.
