- Description
- Hand held light meter in a pear shape with a stainless steel body and leather case. Along both sides of the meter are a series of protruding lines that allow one to safely grip the object. On the viewer right there is a pointer lock, which is locked when positioned upwards and released when positioned downward. At the bottom of the artifact there is a metal hook, which has a black string running through. In the top of the light meter there is clear plastic covering. Written in capital letters is “WESTON MATER IV” above the light scale. The lights scale contains the numbers “0” “25” “50” “100” “200” “400” “800” “1600,” which means that the 2 values calibrated on this instrument are 0-50 and 0-1600.Below there is another light scale in the form of a circular face with several figures and a dial that turns/rotates. The dial on the outside has a series of protruding lines to make movement easier and contains a row of figures. This dial controls the lens aperture (f/stop) scale and has a series of values representing the focal length of the lens; “1” “1.4” “2” “2.8” “4” “5.6”. On the same dial there is also the letters “EVS,” which stands for the exposure value setting with a cut out window that reveals the EVS values. Working in a clockwise direction (on the same dial) there is also the letters “U,” “A with “1/2” over top,” an enclosed arrow that is known as the normal arrow, a “C” with “2x” on top of it, and a “0”. As this dial is turned it reveals a partly red baize and black numbers on a silver background that represents the shutter speeds in fractions of seconds. The inside dial has a series of light scale values and an exposure index window that line up with the “U,” “A,” normal arrow, “C,” and “0.” On the opposite side of the exposure index window is the exposure index knob. On the rear of the meter there is a black plastic covering that contains several circular cut outs that are called a hir.ged baffle. This can be swung open (against the case) using the gold latch, which clips into a tiny hole or socket when the user wishes it to be closed. When opened the light sensitive photo cell is directly beneath this baffle and contains several protruding circles. When the baffle is open, the scale range is 0-50; when the baffle is closed, the scale range is 0-1600. Below there is an oval shaped face with extensive information that is held in place with two small screws on both the viewer left and right side. There is black lettering on a silver background that reads “UNIVERSAL EXPOSURE METER” “MODEL 745” SER.W” and “107522” engraved. Below the manufacturer information is listed; “DAYSTROM. INCORPORATED” “WESTON INSTRUMENTS DIVISION”. “NEWARK. N.J.. U.S.A.” In the middle there is a gold-coloured screw with the words “ZERO CORRECTOR” written in black. On the viewer left side of the zero corrector there is patent information; “U.S. PATENTS” “2463770” and on the viewer right side “FOREIGN PATS” “CAN. 411975”. At the very bottom on either side of a circular cut out are “ASA” and “K=1.0” written. Underneath “MADE IN JAPAN” has also been written.There is also a brown leather case with this object. The front has “WESTON” written in gold letters. On the viewer left there is a brown button that allows the case to be opened or fastened shut. The leather has been stitched together with light brown thread that is visible. The bottom of the case has an opening for the black string to be strung through so that the light meter and case are attached. On the rear there is a brown leather strap stitched.
