Campbell Scientific CS512 Oxyguard Type III Dissolved Oxygen Probe

7. Programming

In the CR510, CR10X, and CR23X datalogger, Instruction P1 or P2 can be used. Example 1 uses a single-ended measurement for the CS512 probe; example 2 uses a differential measurement. The example measurement instructions that follow do not store data to final storage. Additional instructions (typically P92, P77, and output processing instructions such as P70) are required to store data permanently.

In the CR1000, CR800, CR850, and CR3000 dataloggers, instruction VoltDiff or VoltSE is used to measure the CS512 probe.

EXAMPLE 3. Sample Program using VoltSE

VoltSE (DOmV,1,mV250,1,1,0,_60Hz,1.0,0)

EXAMPLE 4. Sample Program using VoltDiff

VoltDiff (DOmV,1,mV250,1,True ,0,_60Hz,1.0,0)

In the CR200 series dataloggers, only the instruction VoltSE is used to measure the CS512 probe.
