Set the Luminous-Field Diaphragm

• The pushrod (2-6/1) for the luminous-field

diaphragm has two positions:

− pushed in: the full field of view is visible

without restriction.

− pulled out: the visible field of view is reduced

to approx. 1/3 of the overall diameter. This

can be useful as an aid to find the object

plane, i.e. the visible diaphragm is focused.

Furthermore, this restriction of the field of

view enables reduction of the false light

portion of weakly reflecting reflected-light

specimens.

Connecting the Instrument to the

Line

The microscope can be operated using line

voltages of 100 − 240 V without conversion

• Connect the line cable (2-7/1) with connector

to the instrument socket (2-7/3) and connect

the earth-contact plug to the line.

• Switch on the instrument via the on/off switch

(2-7/2) on the left-hand side of the instrument.

• The green LED integrated into the on/off

switch lights up to indicate that the machine is

ready for operation (switch in „I“ position).

The integrated halogen lamp 6 V, 30 W must

also be on.
