The first video conference for a factory acceptance test took place in April 2020. In order to ensure that all deadlines could be met and all deliveries could be made on time, the first functioning solution was still a rather pragmatic approach involving a helmet-mounted iPhone. The camera feed from the phone was sent via a Microsoft Teams conference to the customer so that they could watch the engineer carry out every step of the process. Since then, the process and technology used have been continually optimized, and professional helmet cameras are now used. However, the procedure has largely remained the same: The employees start by explaining what will happen during the acceptance test, check the scope of delivery, and explain the functions of the high-voltage test system along with its components. Afterwards the test itself is performed and, via the camera, customers can see exactly what the test engineers are doing. As the final step, the results are discussed jointly in exactly the same way as if the customers were present on-site. Once the dispatch logs are signed by both parties the product is released for shipment.
