7. Startup

•Insert the centering key through the corre- sponding openings (44b.1) on both sides of the condenser.

•Turn the centering key until the dark ring (phase ring in the objective) is congruent with the slightly narrower bright ring (light ring in condenser) (44a.c).

Note:

When changing the objective, the centering key must no longer be in the corresponding open- ings.

•Repeat the process for all other phase con- trast objectives.

•Always remove the centering keys after the centering procedure.

7.7Setting the motorized polarizers (DM4500 P/DM5000 B)

•Select the POL method (one of the variable function keys on the stand or on the Leica- Screen).

•Insert the centering key into the correspond- ing openings (44b.2) on the condenser.

•Set the optimum extinction (max. darkness).

7.8 Adjusting the light sources

Transmitted-light axis (TL) with lamp housing 107/2

The lamp housing 107/2 with a 12 V 100 W halo- gen lamp is fixed. Centering the lamp is not re- quired.
