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.
