output into environmental units can be done via slope and offset for simple
sensors, and via equations for non-linear sensors.

Analog Type
This setting directs the input channel to which the sensor should be connected
and the type of analog measurement to make. These options are available
0-5V A

0-5V A and 0-5V B
Connection A: 0-5V A Terminal #25 and AGND Terminal #26
Connection B: 0-5V B Terminal #23 and AGND Terminal #24
Inputs 0-5V A and 0-5B are designed to be general purpose 0-5 Volt DC input.
While sometimes referred to as a single ended input, it is designed to measure
voltage with respect to analog ground. These inputs have a high impedance (>2
Meg Ohms) and will not load down or draw significant current. The input range is
0V to 5V. Negative voltages with respect to AGND may NOT be measured on
these inputs.
To connect a sensor:
The voltage
output
by the sensor should be connected to either A or B.
The
analog ground
from the sensor needs to be connected to AGND.
