Output Configurations
If other options are needed for the application, the output jumpers have to be
configured before the unit is powered up. Each jumper selection is independent from
the others, except for the “Start point selection” jumper, which affects both, Out(1) &
Out(2), linear outputs. Alternative measuring ranges of the outputs can be selected
with the software UIP (version 4.3 or later).
