ON/OFF Key
The ON/OFF key is shown on the top left of the keypad. When turned ON an initialisation
screen is displayed on the LCD showing the instrument’s serial number and software revision.
Once this appears, the instrument can be started by pressing the ENTER key once – the
initialization screen is then replaced by a MAIN MENU which provides access to the remaining
functions.
Menus and the menu selection keys
The Portaflow 330 menus are arranged hierarchally with the MAIN MENU being at the top
level. Menu navigation is achieved by three keys on the right hand side of the keypad which
are used to scroll UP and DOWN a menu list and SELECT a menu item. When scrolling
through a menu an arrow-shaped cursor moves up and down the left hand side of the screen
to indicate the active menu choice which can then be selected by pressing the ENTER
(SELECT) key.
Some menus have more options than can be shown on the screen at the same time, in which
case the ‘overflowed’ choices can be brought into view by continuing to scroll DOWN past the
bottom visible item. Menus generally ‘loop around’ if you scroll beyond the first or last items.
If you select Exit it usually results in taking you back one level in the menu hierarchy, but in
some cases it may go directly to the ‘Flow Reading’ screen.
Some screens require you to move the cursor left and right along the display as well as up
and down. This is achieved using keys 5 (scroll LEFT) and 6 (scroll RIGHT).
