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.
