Screen Operation
The screen is designed to display information and is used to enter data. The
following describes the type of buttons and data boxes that will be encountered
during the calibration process.
A yellow data button is used during calibration to enter a
measured volume or value. When the yellow area of the data
button is highlighted, it will change to a darker yellow. The
data can be changed using the [] and [
▬
] data entry keys or the
value can be entered using the number keys both on the control
panel. Once the data is entered, press the [CONFIRM] key and
the data button changes back to light yellow. The [Escape]
key can be pressed when the data button is dark yellow to abort
the data entry and return it to light yellow. The entered data
does not get stored until the [CONFIRM] key is pressed. A
gray data button means the button is not active.
Screen Button (screen key)
The bottom row of blue screen buttons are selected by pressing
the corresponding screen key directly below the screen button.
By pressing a screen key, the screen will change to the selected
screen directly without pressing the [CONFIRM] key. If data
entry, option change, or menu selection is in process when a
screen key is pressed, a message requiring the operator to press
the [Escape] key or the [CONFIRM] key is displayed instead
of changing screens.
Screen Button (screen change)
Some screen buttons that change screens are not part of the
bottom row of the display. To use this type of screen button it
must be highlighted first. Use the navigation keys ([▲], [▼],
[◄], and [►]) to highlight the desired screen button then press
the [CONFIRM] key. The screen will change.
A screen button is not active if it is gray.
