7. Operation

7.8 Light Sources

•The brightness is set using the function keys (65.5). Then, the INT function keys are as- signed to the currently active axis for trans- mitted light (TL) or incident light (IL).

•For TL and IL:

Settings can be made either in large or small increments. Pushing both INT buttons simultaneously switches between coarse and fine setting. The display indicator changes ac- cordingly.

7.9 Aperture Diaphragm and Field Diaphragm

Both diaphragms are already factory-set to the optimum setting for the current objective.

•The AP (65.2) keys for the aperture diaphragm and the FD keys (65.4) for the field diaphragm may be used to change each diaphragm’s set- ting at any time.

Then, the function keys are assigned to the currently active axis for transmitted light (TL) or incident light (IL).

Caution:

When doing so, old values are overwritten and the new values are stored!

•For Fluo:

The brightness is set in 5 fixed steps (FIM): 100% / 55% / 35% / 20% / 10%

Caution:

While using PH or DF the aperture diaphragm is completely opened and locked.
