7. Startup

Caution!

In older lamps, the structure of the arc is no

longer clearly recognizable. The image is

then more like that of a HG 50 lamp. The im-

age and mirror image can no longer be su-

perimposed exactly. In this case, align both

images.

• Using the collector, defocus the image with

the knob (46.6) until the arc image and mirror

image are no longer recognizable and the im-

age is homogeneously illuminated.

• Replace the lamp adjustment reflector with

the original filter cube.

Note:

Make sure to switch off the instrument.
