GENERAL
The present service manual contains brief information on
the exposure meter 10102 "Leningrad 8" and directions
for use.
Prior to using the exposure meter, study the service manual
with care.
The exposure meter is intended for determining the exposure
conditions (the shutter speed and lens aperture) for a given film
speed value for amateur shooting black-and-white and colour
f ilms.
The exposure meter can be operated in the bright sun and
artif icial light both out- and indoors at an ambient temperature
from minus 20 to plus 45 o C.
SPECIFICATIONS
Exposure meter conforms to GOST 9851-79, accuracy:
class 6.
Exposure meter has:
ovo ranges for object brightness measurement:
f irst range 4.75-850 cd/sq. m,
second range 600-56.000cd/sq. m;
three ranges for oblect illumination measurement:
first range 95.0-18,000 lx,
second range 12,500-1 120,000 lx,
third range 6.00-95.0 lx,
the first and second ranges for object illumination measure-
ment operate when the attachment is used.
Perception angle: vertical - 40o, horizontal - 60o.
Overall dimensions: 54X88X27 mm,
Mass of exposure meter less case and cord: 90 g.

ur DESIGN
The photoelectric exposure meter comprises a selenium pho-
tocell, a moving-coil meter with scales and a calculator.
The shutter speed and lens aperture are determined with the
help of the calculator.
The calculator is composed of two dials: upper and loruer.
The upper dial bears: lens aperture scale from '1 .4 to22 and
film speeds from 3 ro 3,200 GOST (or ASA) units and from 6
y: to 36 degrees DlN.
The intermediate divisions of the GOST (or ASA) scale cor-
respond to values 4,5,8,10, 16, 20,32,40,64,80, 128, 160,
250, 320, 500, 640, 1000, 1250. 2000, 2500.
The film speed value is set with the help of a carrier.
The lower dial bears a scale of shutter speeds for citmeras
from 1/4000 s to 2 min. fractions of a second being indicated as
whole numbers (2 implies 112, etc.l, seconds as " (l ,, is I s,
etc.); minutes as '(f is 1 min, etc.l.
The same dial bears two more scales: a cine camera speed
e' scale from 4 to 95 frames per second with the intermediate di-
vision 6, '12,24,48 and 95 frames per second and an auxiliary
scale figured from 1 to 18.
The lower dial is associated with a ring for setting the auxi-
liary scale.View original page 3Page 4 · Read text

PREPARATION FOR WORK
There are two methods of determination of shutter speed or
lens aperture with the help of the exposure meter.
1. The method of reflected light (object brightness). In this
case the exposure meter is used to measure the intensity of the
light reflected into the camera by the object to be photographed.
When determining the exposure conditions, place the expo-
sure meter at the camera location and direct its window to the
object of interest.
In this case either the first'or the second range is read off
without the opal glass.
2. The method of incident tight (illumination of ob.iectf . In
this case the exposure meter is used to measure the intensity of
the light illuminating the object to be photographed.
When using this method, place the exposure meter at the
object location and direct its window to the camera.
ln this case either the first or the second measurement range
is read off with the opal glass put on the exposure meter
window, or the third range is used without the opal glass, the
photocell being extended.
OPERATION
1. Move the carrier to set the f itm speed by GOST (or ASA)
scale or DIN scale.
2. Depending on the method used, direct the exposure meter
either to the object to be photographed or to the camera, the se-
cond measurement range being previously set.View original page 9Page 10 · Read text

ff the meter pointer does not reach the scare mark,,12.,
change the meter over to a more sensitive (i. e. the tirst) range
by pushing the range switch button fully outwards.
lf with the incident light method the pointer fails to reach
mark "5" due to poor lighting, remove the opal glass from the
meter window and push the photocell button 3s fsr 35 it will go
to bring out the photocell, then read the third measuremenr
range scale.View original page 10Page 11 · Read text

The first measurement range
3. Turn the ring to s€t the auxiliary scale so that it is in the
same oosition relative to the fixed index as the oointer on the
meter s€le.
4. Take the shutter speed reading against the desired value
of the lens aperture or take the reading of the lens aperture value
against the desired shutter speed.View original page 11Page 12 · Read text

The second measurement range
In case you deal with a cine camera, take the reading of the
lens aperture value against the desired camera speed
On the scale the camera speed corresponds to the cine camera
ue angular aperture of ca. 180o.
ue For angles other than that a correction i3 to be introduced.View original page 12Page 13 · Read text

The third measurement ranqe
In cameras of old makes the scales at shutter speeds and of
lens aperture values can differ trom those of the exposure meter.
ln thrs case set the camera for such a shutter speed or a lens aper-
ture which is closest to that from the respective scale of the ex-
oosure meter.
To avoid errors caused by sky light when determining shutter
speed by the rellected lighr method at nature shooting, it is advi-
sable to incline rcmawhat the exposure meter window towards
the ground.View original page 13Page 14 · Read text

STORAGE
The exposure meter should be kept in the closed case at a
temperature from 1 to 40 oC.
Protect the exposure meter and opal glass from dust, dirt and
moisture.
lf the opal glass or exposure meter window glass becomes
dirty, wipe them gently with a clean soft cloth. Never use sol-
vents, alcohol, acetone and the like for this purpose
The "Lerringrad 8" exposure meter is a highly sensitive mea-
hl suring instrument that requires careful handling.
S Protect the exposure meter from sudden iolts and shocks.FI The exposure meter should be repaired at special workshops
onlY.
Since efforts are continually made to improve thb reliability
and performance of the exposure meter, minor changes may be
introduced without special notice.
