Vario: brightness control of the lamp
This control function permits you to select the brightness of the lamp.
In the basic mode, the current brightness of the lamp is shown in the top
display.
Setting the brightness of the lamp
Use the "
∇ " and " ∆ " keys to adjust the brightness of the lamp.
Brightness is adjustable in a range from 1 to 10 in steps of 0.5.
The last brightness setting for the lamp is automatically stored under the
current user ID.
Notes:
– In the adjustment performed here, you set a fixed basic brightness of
the illumination. In configuration mode 2, you can select automatic
(AUTO) for "Brightness as a function of the zoom position" (LIGHT
FUNCT:).
The automatic function ensures that you have an image of constant
brightness across the entire zoom range (0.4 to 2.4). From zoom value
1 onwards, the transmission of the optical system decreases with in-
creasing magnification. The automatic function compensates for this
by increasing the lamp brightness appropriately.
If you have selected a relatively high basic brightness for a large field
of view (low zoom value), the automatic function is unable to sufficient-
ly compensate for the reduced transmission of the optical system re-
sulting from high zoom values.
– You can also adjust the brightness of the lamp by pressing the appro-
priate key on the foot control panel or handgrip.
In configuration mode 1, you can assign the increase/reduce bright-
ness function to the freely configurable keys on the handgrip.
Saving parameter settings
As soon as you have entered a parameter setting, it is saved under the
current user ID.
Path: The basic mode is automatically displayed after the instrument has
been switched on.
