Transmitted Light
For Leica DM2000:
• Adjust the brightness with the dial (57.1).
For Leica DM2500:
• Adjust the brightness with the dial (58.1).
For Leica DM3000:
• For each objective, the light intensity is preset
at the factory. This value can be changed by
using the handwheel (parallel to 57.1 for the
DM2000). The new value is stored for the re-
spective objective and automatically set again
if this objective is selected.
The numbers on the dial are not absolute values,
but are intended to enable reproducible set-
tings. The maximum value is about 12 V, the
marking point of a color temperature of approx.
3200 K.
