Leningrad-2Photoelectric exposure meterInstruction manual version 1962.1. PurposePhotoelectric exposure meter "Leningrad 2" (type U11 / 2) is designed to determineshutter speed and aperture (relative aperture) when photographing in black and whiteand colored negative materials. The light meter can also be used for filming.The exposure meter can be used in bright sunlight and artificial light, in the openair and indoors.1. Exposure scales. 6. Rotary flap.

Principle of operation and designMeasuring mechanism PhotocellThe photoelectric exposure meter consists of seleniumphotocell, microammeter (measuring mechanism) and reading device (calculator).Light through the exposure meter window hits the photocell.Under the action of light in the circuit of a photocell connected tomicroammeter, current is generated.With an increase in the illumination of the photocell, the current increases, as a result of which the deflection of the arrow increasesmicroammeter.The shutter speed is determined using a countdowna device that consists of two disks - the topand bottom. The upper disc has a scale of diaphragms from1.4 to 22, as well as sensitivity scales from 4 to 350units of GOST and from 6 to 27 units of DIN.Exponometer Leningrad 2 Manual 1962- 2 -Exposure meter windowIntermediate divisions on the sensitivity scale according to GOST correspond to 5.5; eleven; 22; 45;90; 180; 350 units.The lower dial has a shutter speed scale from 1/1000 to15 seconds, with fractions of seconds indicated by whole numbers, instead of ½ sec. written 2, etc. Sign ″stands for whole seconds. The same disk containsscale of exposure (light) numbers from 1 to 15.Some cameras have a similar scale.with a central shutter, for example "Iskra" and "Smena-8".A tracking pointer is associated with the lower disc, whichmoves when you turn the dial.The light meter meets the requirements of GOST 9851–61.3. Methods for determining exposureThere are two main methods for determining exposure with an exposure meter:1. The method of reflected light (according to the brightness of the object), in which the exposure meter measures the light,reflected by the subject into the camera.When determining the exposure using this method, the exposure meter window should be directed from the spotshooting on the photographed object, and the photocell must be recessed in the body.2. The method of incident light (according to the illumination of the object), in which the exposure meter measureslight falling on the photographed object.When determining the exposure using this method, the exposure meter window must be directed from the spotlocation of the photographed object on the camera. The photocell must be recessed,and a milky glass is inserted into the window. If the deviation of the arrow is small, you shouldremove the milk glass from the window and pull out the photocell.To extend the photocell, it is necessary to turn the flap clockwise until it stops,to drown the photocell - turn the flap as far as it will go, but counterclockwise.At temperatures above + 50 ° C, the photocell may escapeout of service. This should be borne in mind in hot conditions.climate. It is not recommended to keep the photocell underdirect sunlight.Prolonged exposure to bright light maythere is a temporary change in the readings of the device,therefore open the exposure meter case in bright lightshould only be taken for the time required to determineexcerpts. It is recommended to store the light meter in a closedcase, the photocell must be recessed into the case.Light meter and milk glass are requiredprotect from dust, dirt and moisture.If the milk glass or safety glass is inthe exposure meter window is dirty, wipe itclean soft cloth.Exposure meters can only be repaired inspecial workshops FEEDBACK: I will try to provide you with the best service I can.
