5.1.3 CR10(X) Pulse Channel Example

The following example program uses a pulse channel to read the output from
the rain gage and will work with CR500, CR510, CR10(X), 21X and CR23X;
the CR7 is similar, but has an additional parameter in the Pulse Count
instruction to specify the slot that the Pulse Card is in.
