740 Portable Suspended Solids
3 Configuration
3.1 Menu Mode
To access the main menu, press the MENU key when the instrument is in measure
mode. Pressing the MENU key when the main menu is displayed will return the
instrument to the measure mode. When the main menu is displayed, the keys can
be used to move the selection bar. Pressing the OK key will activate the selected item.
If the instrument is left in any display other than measure mode, it will automatically
return to measure mode after one minute has passed with no key presses. When a sub
menu is displayed, pressing the MENU key will exit the current menu and return to the
previous menu. If a menu consists of more than six items, UP and DOWN arrows will
appear to indicate if there are menu items above or below those displayed.
3.2 Data Entry
To provide the user with a simple interface, the 740 uses three methods of data entry
for the setting of all the user configurable parameters. The various methods of user
data entry used on the 740 are described below:
3.2.1 User List Selection
This method of user data entry is used when a selection from a predefined list of option
is required such as sensor type, display range and backlight mode. The list of possible
selections will be displayed and a small tick will identify the current setting. If the list
contains more than five items, small UP and DOWN arrows will appear on the display
to indicate there are more items than that displayed. To make a selection, the selector
bar can be moved using the keys, to select the required item. Pressing the OK key
will select the highlighted item and a small tick will appear next to it. Pressing the
MENU key will exit the list selection menu.
