B.2.1 CR6 Program for the CS700H
In the following CR6 program, the CS700H is connected to
U1
, and the rain
measurements are reported in inches. This program does not retrieve real-time
status information using the SDI-12 protocol. An example program that
retrieves status information is provided in Appendix B.2.2 ,
