RSE / NRSE Mode for 3 Wire Sensors
Three wire sensors having a power connection, a ground connection, and a voltage output may be connected as shown in
Figure 11 below. The channel should be set to RSE mode which internally grounds the SIG- input. The voltage output
from the sensor (or other source) may then be applied to the SIG+ (non-inverting) input. Set V EXC to unipolar at a
voltage appropriate to power the sensor, and ensure that the V EXC lines are tied to the respective SENSE lines.
If an inversion is desired, use NRSE mode which internally connects SIG+ to ground. The voltage output from the
sensor may then be applied to the SIG- (inverting) input.
