Appendix B. Example Programs

The following example programs use a pulse channel to read the output from

the rain gage. The CR1000 example will also work with the CR800, CR850,

CR3000, and CR5000. CR9000(X) programming is similar to the CR1000

except for having an additional parameter in the PulseCount() instruction to

specify the pulse module’s slot.

B.1 CR1000 Pulse Channel Example Program

'Program records precipitation from one TE525 or TE525WS Rain Gage once a
