Ground: Reference point for single-
ended AI measurements, bias current
return point for differential mode
measurements, AO voltages, digital

Varies Input Analog Input Channels 0 and 1:
For single-ended measurements,
each signal is an analog input
voltage channel. For differential
measurements, AI 0 and AI 1 are
the positive and negative inputs,
respectfully, of differential analog
input channel 0.

Analog Input Wiring
In the differential input setting, connect the the positive lead of the source to the AI(0)
terminal, and the negative lead to the AI(1) terminal. The differential input mode
allows the SensorDAQ to measure a voltage difference on these terminals up to +20V
or –20V in the ±20V range; however, the maximum voltage on any one terminal
cannot exceed ±10 V with respect to GND. In the referenced single-ended input mode
setting, connect the positive lead of the source to either AI channel terminal, AI(0) or
