EXAMPLE 2. Sample CR200 Program

The CR200-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 7-2 shows the wiring for the example.
