2.7 Trackballs and touchscreen
Trackballs
The SpotChecker features two trackballs to operate
the graphical software interface. Both trackballs work
independently of each other and independently of a
connected mouse.
Each trackball has a big and a small button. The big
one of the respective trackball is equivalent to the left
mouse button, the small button of each trackball to the
right mouse button.
You can operate both trackballs simultaneously, e.g.
move the mouse pointer with the right trackball and
trigger functions with the buttons of the left trackball.
Touchscreen
The SpotChecker is equipped with a touchscreen
enabling a direct operation of the menus appearing on
the screen.
The operation by means of a mouse
(selecting and clicking) is in this case replaced with di-
rect touch on the screen. A mouse pointer is therefore
not necessary.
To select or to mark an element of the user interface,
just touch the corresponding point of the screen brie
fl y
with your fi nger.
A
Attention:
Do not touch the touchscreen with any hard or sharp-
edged objects (e.g. ball-point pen or screw driver).
The touch-sensitive surface may be severely dam-
aged by them. Do not apply any high pressure to the
screen, the touchscreen needs only slight pressure to
react.
