As you push the control lever
a
in the di-

6),
the LED readout
@
will display the lamp voltage.
T w o LEDs o n the left side indicate the volt-
age from OV to 6V, and twelve LEDs o n the
right side from 6.5V t o 12V in 0.5V incre-

(Fig. 7)
2 ) Looking through the both eyepieces w i t h
both eyes, adjust the interpupillary distance,
sliding the knurled dovetail slides of the
right and left eyepiece tubes, until perfect
binocular vision is obtained. (Fig.
8)
3) Looking through the right eyepiece ( w i t h
cross hairs or micrometer) w i t h your right
eye, rotate the upper helicoid ring
Q )
of the
eyepiece until the cross hairs (or micrometer)
are sharply focused. (Fig.
8)
4) Focus o n the specimen with the coarse and
fine adjustment knobs so that the sharp
images of the specimen and cross hairs (or
micrometer) can be obtained simultaneously.
5)
Now look at the image through the left eye-
piece with your left eye and rotate the
diopter adjustment ring
@
t o focus on the
specimen without using the coarse and fine
adjustment knobs. (Fig.
