Each basic measuring range can be divided into three specified measuring
ranges. In the case of devices with a Modbus interface, this is parameterized
via the interface. For devices with an analogue interface, the desired measuring
range can be set using the DIP switches. All options are listed in the measure-
ment accuracy table.
