How It Works
Viking Two guides technicians through a structured inspection process, ensuring consistent and thorough documentation every time.
Plug Viking Two into the Type 2 charging station socket and pair with the companion app via Bluetooth.
Simulate EV states, read CP/PP signals, verify phase voltages, and monitor the station's response in real time.
Enter customer details, capture photos, complete the safety checklist, and record all measured parameters.
Submit the inspection — a professional PDF report is generated and emailed to both the customer and your company.
