4.5 Customizing the Program
Following examples show how to modify the parameters, save and compile the program before
making it ready to send to the logger.
Procedure to Modify the Program:

Open CR Basic Editor by clicking on CRBasic icon .

Open the file Dynamet 5.CR1 in the editor.

Now identify the site-specific or timing loop variables at the top of the program as shown
in the previous above.

Modify values assigned to the constants as required.

Save the program under a different file name (Dynamet 5SiteA.cr1) so that the original
program is not modified. Save the program and compile.

Now the new program Dynamet 5SiteA.cr1 is ready to send to logger.
Example 1:
Dynamet 5 weather station is setup at a site that is only 50ft. above the sea level. The system is
installed on top of a tower whose height is 20m. Roughness parameter of the location of the
installation is found to be 0.001m and the specific air heat capacity is 1002.0 J/KgC. Modify the
program Dynamet 5.cr1 and send to logger so that the Dynamet 5 station can calculate ET
using the Lascano-VanBavel RCM algorithm.
From the program it is clear that the required station parameters are,
zom = 20 m
zot = 0.001 m
elf = 50 ft.
has = 1002.0 J/KgC
Open the program in Dynamet 5.CR1 in CRBasic. As shown below are the default parameters.
