Note
Consider this behavior when planning a static distance measurement. When planning a
dynamic distance measurement, ensure that the distance between sensor and measuring
object is adjusted so that a connected multimeter reads a DC voltage of approximately -10
V. This standard adjustment is always recommended (see

Supply boost
The sensor supply boost in the A6500-UM card must be activated or deactivated
depending on the maximum voltage U
configuration of the A6500-UM card where the AMS EZ 1000 Converter with Zener barrier
is connected to and go to Input → Sensor supply boost. See
