The analog output channels of the PCI-1724U have output ranges set individually per channel, rather than being set for the whole subdevice, so set a range_table_list for the subdevice rather than a single range_table.
This is mostly for the benefit of user-level as in fact the output ranges of each channel are partly set by per-channel hardware jumpers (to choose between voltage and current loop output) and partly by the offset and gain calibration subdevices.
