5-1C H A P T E R 5Initial Setup and General OperationsThis Chapter describes setup and operation of the flowmeter using the Touch Screen Display. Thealternative method using a PC with “Accuflow” is described in Chapter 6. Chapter 7 contains definitionsof each parameter and variable. (Note: The instrument will not be damaged by entering incorrectparameters.)Touch Screen LCD Display, Parameters and VariablesThe touch screen LCD display is used to set up the flowmeter, start measurements, and observe themeasured variables and status messages. Once the flowmeter starts taking measurements, it will continueto do so at a rate defined during setup. Flow measurements can be interrupted or halted from the display.Set up the flowmeter by entering appropriate values for various parameters. Parameters define thegeometry of each meter section and govern the operating modes of the flowmeter. Variables provide aview of measurements when the flowmeter is in normal “Measure” mode. At the end of this chapter typicaldisplay screens of the variables are shown.MenusAfter power-up, the flowmeter always returns to the “Measurement” mode, with the display showing aLOGIN page. IF the ADMIN LOGIN password is not known, then simply press OK to login as a GUEST.An ADMIN can view all of the measured variables and change the flowmeter’s parameters. A GUEST canonly view the measured variables.Commands and control parameters are entered into the flowmeter using menus shown on the display. Tocause the menus to appear, press the Parameters icon in the HOME screen. Some menus display theavailable options, (e.g., “Pipe” or “Open Channel” mode), and you choose between them; in most cases,you need to enter data. The next section describes how to access these options.Stepping Through the Parameters MenusSix buttons are used to navigate through lists of parameters. The vertical navigation bar on the right side ofthe display will allow a user to select a specific page number when there is more than one page available.The icons at the bottom of the screen will allow a user to select which parameters to view or change. Anyicon that is blue is a selectable icon and any icon that is gray shows which icon a user has currentlyselected. To change any parameter value, simply press on the numeric box under the parameter label.When the numeric value of the parameter is touched, a numeric entry pad will be displayed across the topof the display. The value can be changed and then any part of the screen can be touched to store the value.Any changed parameters will be stored in non-volatile memory (provided that the parameter AUTO STOREPAR’S in the System menu is set to 1). The flowmeter itself will return to Measure mode even if data is notbeing shown on the display (at this time any analog outputs or ModBus communications will begin to
