Attach the two wires to the connection points on the rain gauge and fit the logger into place.  On the 
Kalyx this process involves pushing the base of the logger onto the raised bar of the gauge until the 
logger clicks into place and a firm attachment is achieved.   

The logger is now fully set up and the gauge is ready for field deployment.  For details of how to carry 
out this task refer to the individual rain gauge manual.

Data collection 

 

Data can be downloaded from the logger and saved as .txt or .csv file.  The data format is simple and 
easily accessible.  The data is separated by a comma by default.  When saved as a .csv it will therefore 
look like the following:
