5.2 Menu Sequence
The listing below gives a general overview of the standard top-level display menu
sequence when running firmware version A001. The ESC pushbutton is used to
toggle between the process mode (PI screens) and the Setup menus.
The listing in Section 5.2 shows the standard display menu sequence and sub-
menus using the UP button to move through the menu items. The first message
displayed the first time the ESC button is pressed after the meter is powered up is
“Prog. Protection ON”. Thereafter, pressing the ESC button while the flow meter
is in monitoring mode (PI screens) will display the parameter that was last exited.
Program Protection may be turned “off” by pressing the ENT pushbutton when
the Program Protection menu is displayed. The firmware will prompt with
“Change Prog Prot”. Pressing UP or DN button will toggle current protection sta-
tus. If password is set to any value more than zero, the firmware will prompt with
“Enter Prot Code”. User has to enter up to 3 digits program protection code, in
order to be able to access password protected menus. Once correct password is
entered, program protection is turned off until unit is powered up again.
When the last menu item is reached, the firmware “wraps around” and scrolls to
the first item on the menu once again (see Figure 5.5). The menu items in the first
column are upper-level configuration mode functions. Submenu selections are
shown on the Figure 5.6). The allowable selections of sub-menu items which are
selected by tabular means are shown in detail in Section 5.3.
