The trackball is often used with the Pad panel.
Turning the trackball in the direction of the axis
X changes the first parameter of the active
function; turning the trackball in the direction
of the axis Y changes the second parameter
of the active function. Holding the F11 key locks
the first parameter of the active function; using
the F12 key locks the second parameter of the
active function.
7.4 Control Panel
The control panel has several knobs and colour touch screen. It was developed by TESCAN
exclusively for SEM control. It is not a standard SEM part.
The manual knob set provides the user with a simple and straightforward way of operating
the microscope. It can control the stage, magnification, focus, beam intensity, scanning
speed and other parameters.
Most common functions have dedicated knobs.
The three upper knobs have variable function;
their actual function is shown at the bottom
of the touch screen. Several important
parameters are shown in the middle of the
display. There are also shortcuts to the
automatic functions (focus, brightness/contrast,
image acquisition) in the header.
