CS700 and CS700H Rain Gage
5. Datalogger Programming
This section is for users who write their own datalogger programs. A
datalogger program to measure this sensor can be created using Campbell
Scientific’s Short Cut Program Builder software. You do not need to read this
section to use Short Cut.
5.1 CS700 Programming
The CS700 is measured using the Pulse Count instruction with the switch
closure configuration code. The multiplier used in the Pulse Count instruction
determines the units in which rainfall is reported. In all dataloggers, a
multiplier of 0.01 converts the output to inches and a multiplier of 0.254
converts the output to millimeters.
5.1.1 CS700 Pulse Channel Example Programs
The following example programs use a pulse channel to read the output from
the CS700.
5.1.1.1 CR1000 Pulse Channel Example
Although this example is for the CR1000, the CR800, CR850, CR3000, and
CR5000 are programmed similarly.
