 THE DISPLAY & MENUS
The display allows menu selections to be viewed and selected. These
selections instruct the 2020we/wi to perform specifi c tasks. The menus
are viewed in the display using two general formats that are followed
from one menu to the next. Each menu is a list of choices or selections.
The display has a header line at the top and a footer line at the bottom.
The header displays the title of the current menu. The footer line
displays the time and the date, the data logger status and the battery
status. The menu selection window is in the middle of the display
between the header and the footer.
The menu selection window displays information in two general formats.
In the fi rst format only menu selections are displayed. Up to 4 lines of
menu selections may be displayed. If more selections are available they
can be viewed by pressing the arrow buttons to scroll the
other menu selections into the menu selection window. Think of the
menu selections as a vertical list in the display that moves up or down
each time an arrow button is pressed. Some menus in the
2020we/wi are looping menus. The top and bottom menu choices are
connected in a loop. Scrolling down past the bottom of the menu will
lead to the top of the menu. Scrolling up past the top of the menu will
lead to the bottom of the menu.
