OPMI: setting the lamp brightness
This function permits you to set the lamp brightness.
In the basic mode, the lamp brightness currently set is shown in the upper
display field.
The middle display field remains empty and the associated keys "
∇
" and
"
∆
" have no function.
If the suspension system is equipped with a second halogen lamp
housing, the brightness currently set for the second lamp is displayed in
the middle display field.
Adjusting the settings
Keys "
∇
" and "
∆
" allow you to change the lamp brightness.
– Check that the lamp brightness can be varied and that brightness var-
iation has an effect on the surgical field illumination. Perform this
check across the entire control range:
– Halogen: 0.1 ... 1.5
– Xenon: 0.1 ... 1.8
The brightness can be adjusted in the following ranges:
– Halogen: 0.1 to 1.5 in steps of 0.1
– Xenon: 0.1 to 1.8 in steps of 0.1
A beep sounds when brightness level 1.0 has been reached. Level 1.0
corresponds to 500 mW/cm

sr, see ISO 10936-2.
