CS511-L Dissolved Oxygen Probe
7.2.1.2 Example CR200(X) Program
The CR200(X)-series must use the VoltSE() instruction since these dataloggers
do not make differential measurements. If the other CRBasic dataloggers use
the VoltSE() instruction instead of the VoltDiff() instruction, their
programming will be similar to this example. TABLE 7-3 shows the wiring for
the example.
