The Electro PJP CPI controller having a set of one IMD test box and two IP2X fused probes leads. It is used for checking the permanent insulation monitors (CPI) of IT earthing systems. The CPI-Test385A offers electrical resistances of 385 ohms, 770 ohms, 3.5k ohms, and 85.5k ohms between its black 4 mm banana terminal and its other 4 mm banana terminals. The "low" resistors are used to simulate a fault and thus cause the CPI to react. Electrical safety CAT IV 250V
