The default is 1. Selections 1 or 2 will convert the full input current span down to 0 milliamps and
produce negative values below 4 mA. Selection 1 produces engineering unit data in microAmps.
These also enable an "Open Wire" diagnostic bit which is true whenever the input falls below the
normal range.
