It is factory equipped with a 60-cycle generator, an automatic startmarker and a manually operated cue marker, designed to work with all ¼" tape recorders equipped with the pilotone system. The 60-Cycle Signal Generator A miniature generator is built into the camera. When the camera runs at 24 fps, the generator ooutput is a 60-cycle signal of approximately 1. 2 volts. The output appears across pins 1 and 2 of the camera's 5-pin Tuchel outlet, after a 300 milli-second delay. [. . . ] Both can be zeroed easily by their respective setting discs (22/23). Film Gate The Arriflex film gate is extra long (3 inches) and has a full-length rear pressure pad with a side pressure rail. Cross stages around the picture frame both on the front and back plates prevent "film breathing". Made of stainless steel, tapped to high precision and wear chrome-plated, the Arriflex film gate is probably one of the most trouble-free yet highest quality film gates of any camera. It is important to clean the gate regularly of film emulsion and film base deposits. Use only the plastic skewer supplied with the camera and a clean untreated optical cloth. Registration Pin With the film gate opened, the registration pin can be seen just above the transport claw. Its function is to locate the film precisely and to hold it in place during the moment of exposure. The registration pin ensures rock-steady pictures, a repetitively precise film line, and increased tolerance against film pitch changes. Never force the registration pin in any way while cleaning the gate, only activate it by turning the motor inching knob [27]. Film Transport Claw The film transport claw engages the film from the front, the emulsion side. Watch its action by turning the inching knob (27) and note that it engages the film while the registration pin is lifting out of the perforation. This way, during the entire frame cycle, there is always one claw engaged for positive control of film. Mirror Reflex Shutter The mirror reflex shutter is the heart of the Arriflex reflex system. It rotates at a 45° angle between lens and film plane and reflects to the ground glass of the viewfinder exactly the same image as is registered on the film. All of the light rays reach the film through the lens without any interference while the shutter is open, and are alternately reflected to the ground glass only while the shutter is closed. Thus the film, as well as the eye, always gets 100% of the light transmitted by the taking lens. The effective shutter opening is 180° and gives the following exposure times at various speeds: 8 FPS ­ 1/16 sec. 48 FPS ­ 1/96 sec. As this table indicates, the exposure can be calculated for the camera speed by doubling the FPS figure and reading the result as a fraction of a second (180° shutter only). Tripod Sockets Two tripod threads, one 1/4" and one 3/8" size, are provided in the bottom of camera housing. This socket is made of tool steel and is a replaceable insert in the aluminum camera housing. Many standard tripod screws might be too long and trigger the built-in switch for the pistol grip. An excessively long tripod screw could even damage the switch housing inside the camera. The standard length for tripod screw is 7mm = 0. 280 inches. Camera Loading & Threading Turn cover lock (14) from "C" to "O" and lift cover. Lay cover down and be sure switch is in OFF position otherwise switch activating pin could get bent. Both spindles have an automatic lock to hold film spool in place in any camera position. To take film spool out, push button in center of spindle and tilt camera sideways. [. . . ] All later model torque motors are equipped with a grounding plug for a small wire, which leads directly from the negative pole of the battery cable to the torque motor. The most probable cause of torque motor failure is the lack of sufficiently good ground contact and the use of this wire is recommended at all times. Older torque motors can be retrofitted with this feature. Servicing and Maintenance The Arriflex 16S is built with utmost precision and is famous for its ruggedness. It will give absolute satisfaction if treated as any precision instrument should be treated, and if serviced at regular intervals, consistent with the amount of use, and the following recommendations.
