Met One Rain Gage Models 380 and 385

5. Datalogger Programming

5.1 CR10X Programming

This section is for users who write their own 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.

The Model 385 rain gage is measured using the Pulse Count instruction

configured for a switch closure. In all dataloggers, a multiplier of 0.01

converts the output to inches and a multiplier of 0.254 converts the output to

millimeters.

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 or 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.

Output Instruction 72, Totalize, is used in the output section of the program to

output the total rainfall over the output interval. This section should be

executed every scan and not placed in a subroutine or conditional statement.
