Automatic Light Control (ML124 ALC and BL124 ALC models)
ML124 ALC and BL124 ALC models have a special function called “Automatic Light Control”.
The level of light is adjusted by the microscope in order to maintain the same level as the one the user has
chosen, no matter if the aperture of the diaphragm changes, another objective is inserted, opacity of the
sample changes, etc.
1)
Set the focus on the sample as described in the previous chapters, using the objective of your choice.
2)
Rotate the brightness adjustment knob in order to get a comfortable level of illumination.
3)
Press the ALC button on the side of the microscope.
Now the ALC system is working: if you open or close the aperture diaphragm or change objective, the system
will try to maintain the same level of illumination as the one you stored when you pressed the button.
4)
Press the ALC button again to return to a manual control of illumination.
