Depending on the CT input definition (1/5 A) by customer settings. easYgen-XT
hardware covers both 1 A and 5 A ranges.

Some senders, like the VDO senders, are operating in the working range 0 to 200
Ohms. For sure, the 0.5% accuracy cannot be directly assigned to these senders.
Therefore the accuracy percentage tolerance will be expanded accordingly. On the other
hand, measurements have shown that under usual circumstances (at 20°C, no EMC
surge or burst present) an accuracy of 1% for such senders can be kept.
