Note
You can calibrate NI 6011E and NI 6030E/6031E/6032E/6033E circuitry for either
unipolar or bipolar polarity. If you mix unipolar and bipolar channels in the scan list and
you are using NI-DAQ, NI-DAQ loads the calibration constants appropriate to the polarity
for which AI channel 0 is configured.

To be flexible enough to interface with various signal sources, E Series
devices have three different terminal configurations, also referred to as
input modes: Non-Referenced Single-Ended (NRSE) input, Referenced
Single-Ended (RSE) input, and differential (DIFF) input. Table 2-4
describes the three input configurations.
Table 2-4. Analog Input Terminal Configuration
A channel configured in DIFF mode uses two AI lines.
One line connects to the positive input of the device
programmable gain instrumentation amplifier (PGIA), and the
other connects to the negative input of the PGIA.
A channel configured in RSE mode uses one AI line, which
connects to the positive input of the PGIA. The negative input
of the PGIA is internally tied to AI ground (AI GND).
A channel configured in NRSE mode uses one AI line, which
connects to the positive input of the PGIA. The negative input
of the PGIA connects to the AI sense (AI SENSE) input.
Refer to the
Connecting Analog Input Signals
about using these input configurations.
