may result in unreliable measurements because there is
no way to ensure that the input signal is within 10 V of
COM.

Connecting NRSE Voltage Signals

You can connect non-referenced single-ended (NRSE) signals to
the NI 9205.

In an NRSE configuration, the NI 9205 measures each channel
with respect to AISENSE. An NRSE configuration provides
remote sense for the negative input of the PGIA that is shared by
