Many other possible ranges are possible by physically changing the resistor values that
make up the attenuator circuit.
Differential measurements require two channels. As the name differential implies, the dif-
ference in voltage between the two adjacent channels is measured rather than the differ-
ence between the input and analog ground. Voltage measurements taken in the differential
mode have a resolution of 12 bits, with the 12th bit indicating whether the difference is
positive or negative.
When using the differential mode, the input can be either positive or negative, but do not
exceed the maximum range by more than 20%.

tainly lead to inaccurate A/D
conversions. To allow for such
differential measurements, the A/D Converter Card uses a 2.048 V reference voltage. This
allows input voltages that are negative with respect to analog ground. Table 6 provides the
differential voltage ranges for this setup.
