Be careful of light-emitting diode radiation

when using the LED illuminator. Do not look

directly into the illuminator with your bare eyes

from a short distance. When adjustments are

required, the intensity must be reduced

accordingly via the potentiometer, or a suitable

attenuator must be used.

☞

The operation life with battery operation

strongly depends on the brightness set and the

loading capacity of the battery.

2.8.4 Attaching LED illuminator

• Insert LED illuminator (2-15/3) in the

condenser carrier (2-15/1) in the same way

as the Abbe condensers.

• Tighten both centering screws (2-15/2) until

the LED illuminator lies approximately in the

center of the beam path.

• Use condenser drive (2-15/4) to move the

condenser carrier into the topmost position.

Power to the LED illuminator can be supplied

either via the line power unit or, independent

of the line, via a commercially available 9 V

Alkaline battery (9 V / Ni Cd battery block) in

the integrated battery compartment, or via an

external voltage source ranging from 11 to

14 V DC (e.g. 12 V car battery or battery

pack C). The external voltage source must

permit a constant current of up to approx.

120 mA to be loaded.

The LED illuminator provides pleasant, color-

neutral white light with a constant color

temperature (approx. 7500 K) independent of

the set brightness. It is suitable for objectives

ranging from 2.5x to 100x. The light-emitting

diodes have a long life and cause only minor

operating costs.

Operation with power unit

• Insert country-specific adapter (2-16/10)

into the power unit (2-16/9).

• Insert angled connector of the power unit

(2-16/9) into the +12 V socket (2-16/2) of

the LED illuminator (2-16/1).

• Connect power unit to the line.

• Attach the cable to the back of the stand

with the self-sticking cable ties included.
