LaMotte 2020i Turbidimeter - Manual (Page 34)

The Display & Menus
The display allows menu selections to be viewed and selected. These selections instruct
the 2020 to perform specific 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 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 first
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 (
‡ or ˆ) 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 (
‡ or ˆ) is pressed. All menus in the 2020 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

An asterisk,
*, will start in the far left position of the top line in the menu choice
window. To move the
* press the up or down arrow buttons (‡ or ˆ) to scroll through
the menu selections. The
* in the display corresponds with the *IOK button. Pushing
the
*IOK button selects the menu choice which is adjacent to the * in the menu
selection window.
In the second format the menu choice window takes advantage of the graphical
capabilities of the display. Large format graphic information, such as test results or
error messages or the LaMotte logo is displayed. The top three lines of the display are
used to display information in a large, easy to read format. The menus work in the
same way as previously described but only one line of the menu is visible at the bottom
of the display. On the lower right side of the display small up and down arrows (
‡ or
ˆ) indicate that other menu selections are available above or below the one visible
lines of the menu.
