look correct, you get a reading of +9.5V for VIN5, but VIN6 is reading 0V), this is a
good indication that the inputs are configured for unipolar mode (i.e., negative
differential voltage not being reported). Similarly, voltage readings for channels VIN8
and VIN11 would also be incorrect and readings for VIN9, VIN10, VIN12, VIN13,
VIN14, and VIN15 may not be correct (depending on whether the output voltage is
higher than the associated “low-side” differential voltage for the given input channel).

Due to the cable length and relative board location, some of the outputs may show
more noise / inaccuracy than others. This board is intended as a means to verify
basic functionality and connection (including autocalibration features); it is not
intended to provide perfect response for signal performance characterization.
