User Interface, Screen
The controller is equipped with a resistive single-touch screen.
The operation is via a lightweight, single touch of the screen with your finger tip, wearing gloves,
or other non-sharp objects (e. g. a ballpoint pen with retracted ballpoint).
Caution!
Multi-touch gestures, or too rapid entering and typing lead to incorrect entries.
A contact is usually indicated by a short beep acoustically and by a change of the icon view.
Grayscale Setting
Depending on the operating mode, the non-defining informative values on the main screen
(quantity and/or dispensing time) are shown in light gray.
Possibly the contrast needs to be adjusted to the environmental conditions of the device.
Therefore, in the menu for device settings on the bottom left there are two touch field similar to
the contrast characters.
It should be set so that all the contents of the screen are clearly legible, but so that the column is
highlighted by a lighter shade of gray in the space between the fields.
Start Screen
The start screen with the display of the
firmware versions appears for approximately
3 seconds after the device is switched on.
