C.4.2 Enter Site-Specific Variables with Data Logger Keypad or
LoggerNet
After the eddy-covariance station is installed and the data logger is running the
program, connect a CR1000KD Keyboard Display to the CR6 CS-I/O port to
view a custom menu of station-specific variables (FIGURE C-2 ). Use this
menu to enter, view, and modify these variables. Use the up and down arrow
buttons to navigate to different variables. Press Enter to select a variable or to
set a new value after typing it. Press Esc to return to the previous menu.
FIGURE C-2 depicts the structure of the custom menu. Bypass the custom
menu to interact directly with the data logger through the data logger default
menus. To bypass the custom menus, select < System Menu >. If no
CR1000KD is available, these same variables may be viewed and edited using
the LoggerNet connect screen numeric display of variables from the Public
table.

Before fluxes are processed correctly, the user must go through each of the
station variables and set or confirm the assigned values. TABLE C-14 gives
short descriptions of each station variable.
