TE525 Tipping Bucket Rain Gage

7.2 Datalogger Programming

Short Cut is the best source for up-to-date datalogger programming code.

Programming code is needed when:

• Creating a program for a new datalogger installation

• Adding sensors to an existing datalogger program

If your data acquisition requirements are simple, you can probably create and

maintain a datalogger program exclusively with Short Cut. If your data

acquisition needs are more complex, the files that Short Cut creates are a great

source for programming code to start a new program or add to an existing

custom program.

Short Cut cannot edit programs after they are imported and edited

in CRBasic Editor.

A Short Cut tutorial is available in Section 4, Quickstart. If you wish to import

Short Cut code into CRBasic Editor to create or add to a customized program,

follow the procedure in Appendix A.1, Importing Short Cut Code into a

Program Editor. Programming basics for CRBasic dataloggers are provided in

the following sections. Complete program examples for select dataloggers can

be found in Appendix B, Example Programs.

The PulseCount() instruction programs CRBasic dataloggers (CR200(X),

CR6, CR800, CR850, CR1000, CR3000, CR5000, CR9000(X)) to measure the

TE525 rain gage.

• Choose Switch Closure (code 2) for the PConfig parameter.

• The Multiplier parameter determines the units in which rainfall is

reported (TABLE 7-2).

7.3 Siting

Mount the rain gage in a relatively level spot representative of the surrounding

area. Ensure that the lip of the funnel is horizontal, at least 30 cm above the

ground, and higher than the average snow depth. The ground surface around

the rain gage should be natural vegetation or gravel, not paved.

Place the rain gage away from objects that obstruct the wind. The distance

should be 2- to 4-times the height of the obstruction.
