PAVAS Menu Operations

PAVAS Menus are designed to allow the operator to select a function. Menus are selected by scrolling through a list. The list is composed of a name and a brief description of the menu function.

The menu is scrolled by the Up and Down buttons. When the required menu is displayed, the Select button is pressed to start running the menu function. Each menu contains a few display lines to describe how it works and how to operate it. Each group of lines is displayed for two seconds. The line displays can be skipped by pressing any button. The multiple line displays provide embedded Help to simplify learning PAVAS.

The Select key is used to make a choice, the left, right, up and down buttons are used to maneuver the cursor and hence the selection within the menu.

Sometimes menus have many levels. This is true in calibration and configuration menus. After a choice is made on one level, the select button confirms the choice and moves to the next level or ends the menu.

PAVAS always wraps back to the scrolled menu item which allows the operator to repeat the menu task or move to another menu items.

Once Select is pressed, PAVAS always saves the value in non-volatile Flash memory, so the value can be easily recalled even if the power is disconnected. If a value is needs to be changed, simply go back to the menu item and re-enter a new value. Flash memory does wear out after repeated save operations and the memory used has a life of over one million write cycles. Read cycles have no memory wear impact.

The PAVAS menu list rolls over when the start or end of the list is reached. This makes it easier to access a menu item by going Down or Up to reach it.
