Referenced Single-Ended Measurement System
A referenced single-ended (RSE) measurement system, is used to measure
a floating signal, because it grounds the signal with respect to building
ground. Figure 5-9 depicts a 16-channel RSE measurement system. You
only should use this measurement system when you need a single-end
system and your device does not work with nonreferenced single-ended
measurement.

16-Channel RSE Measurement System
Nonreferenced Single-Ended Measurement System
DAQ devices often use a variant of the RSE measurement technique,
known as the nonreferenced single-ended (NRSE) measurement system. In
an NRSE measurement system, all measurements are made with respect to
a common reference, because all of the input signals are already grounded.
