The Triplett Model TEV500 PRO Electric Vehicle Charger Test Kit tests charging stations using basic & advanced diagnostics. PE Pre-Test checks the PE conductor for the possible presence of dangerous voltage against earth. With the CP (Control Pilot) State rotary switch selector various vehicle states can be simulated. You can use the CP Signal output terminals to connect your oscilloscope to check the waveform and amplitude of the CP signal. CP Error “E” simulates the behavior of the station when there is an established short circuit between CP and PE. PE Error (Earth Fault) simulates interruption of the PE conductor. When the CCID TRIP Test Button is pressed, a connection between L1 and PE is established and CCID from the station should abort charging process. A phase indicator LED will illuminate when phase voltage on L1 is present at the charging connector. The Measuring Terminal Outputs L1, L2(N), PE and PP are directly connected to the L1, L2(N), PE and PP conductors of the tested charging station. You can use your digital multimeter for quickly viewing voltage readings on these lines. SAE J1772 complies with North American standards. Includes (1) IEC62196-2 Type 1 female to male adaptor/converter and pouch case.
