Display
The set step width or the positive or negative
position deviation with reference to the zero point
is shown in the display field of the keypad. When
setting functions are performed, the display is used
to show the changeable setting values.
Handwheel for fine adjustment
The handwheel permits
adjustment of the focusing drive (minimum:
0.1 µm) for very precise focus settings at high
objective magnifications in particular. Turning the
handwheel moves the objective slider upwards or
downwards via the focusing drive.
Upwards / downwards direction keys
The upwards / downwards
control the upward and downward movement of
the focusing drive. When one of the direction keys
is pressed, the setting of the focusing drive is
changed at the preset speed until the key is
released again.
The speed of the focusing drive can be roughly set to the slow and fast speed ranges via the Slow and
Speed keys. The relevant speed range LED integrated in the left upper corner of the key lights up.
It is also possible to set the speed of the focusing drive for the Slow and Speed ranges independently of
each other in 16 steps. This allows the single-hand control to be easily matched to individual
requirements.
The steps for the Slow and Speed ranges are set as follows:
• Press the key of the speed range to be changed
(e.g. Slow; the LED of the Slow key lights up).
• Press the Set Speed Slow key. The current
speed step is shown in the display of the
keypad.
