User manual PROFOTO PRO-81

[. . . ] When mounting umbrellas, do not touch flash tubes or modelling lights with the metal shaft - risk of high voltage. Never connect accessories of other brands without consulting an authorised service station. 33 - 41 The Pro-7 system consists of the following products: Generators: Pro-7a 1200 och 2400 Pro-7s 1200 och 2400 Pro-7b 1200 Heads: Pro-7 head Pro-7b head Pro-7 twin Pro-7 ring Pro stick All Profoto reflectors and accessories fit the Pro-7 system 3 Thanks! Thanks for showing us your confidence by investing in a Profoto Pro-7 system. What pushes us is the conviction that we can even offer the most demanding photographer yet better tools. [. . . ] The white ready lamp button [11] will light up when the generator is fully charged. The characteristics of the light vary (please see "Autobracketing" page 20). When the generator is fully charged a short "beep" can be heard. The red indicator [16] will light up and the "beep" will sound if the energy dial A [5] is in the A ONLY area and the dial B is not pointed towards the red indicator. Point dial B towards the red indicator and the "beep" will disappear. If a flash is released before the generator is fully charged a long "beep" will sound, indicating an underexposed frame. Reliability Testing - The R-Test The Profoto R-test guarantees that all products leaving the factory meet the very high standards required of professional equipment by professional photographers. The R-test is a rigorous performance test that Profoto generators are put through - 720 full power flashes are released during one hour, which is equivalent to 20 rolls of 35 mm film. After the test the equipment is examined to see that all parts have kept a normal operating temperature and are not malfunctioning in any way. All Profoto products are subjected to the R-test prior to being shipped. 22 [11] Colour Temperature [12] [16] The colour temperature is constant and reliable regardless of the energy output chosen with the dials A, B1 & B2. Each 1/6 increment reduces the colour temperature by 50° Kelvin, which means a total downscale of 400° Kelvin. Mains Connection connected to all common mains voltages 90-240V and 50-60Hz. The green lamp below the handle indicates that the generator is receiving power from the mains. Warning: Never use ordinary household extension cords to elongate the power cable. Pro-7s 1200/2400 Use the included power cable to connect to the mains power supply. The generator can be 27 [2] Connecting Lamp Heads [4] [5] One or two lamp heads can be connected to the lamps head sockets [2]. When connecting the lamp head plug, align the dots on the plug with the white dot on the generator panel. Energy Control The energy output is regulated with the control ENERGY [5]. The energy can be adjusted in 1/6 f:stop increments, from 1/1 down to 1/32 of the total energy (equivalent to six f:stops). At any change of the energy output the white ready lamp [9] will start flashing indicating that the energy needs to be dumped i. Choice of Modelling Light The control marked MOD. LIGHT [12] is used to choose the following alternatives: OFF 1/1 1/2 Modelling light is turned off Modelling light is receiving the designated proportional energy at full intensity determined by the position of the ENERGY control [5] Modelling light* is receiving the designated proportional energy at half the intensity determined by the position of the ENERGY control [5]. MAX Modelling light is at maximum light output regardless of energy setting When connecting two lamp heads or a Pro-7 twin the modelling light proportionality is automatically adjusted. * The alternative 1/2 proportional modelling light is chosen in those cases when a Pro-7/1200 and a Pro-7/2400 are used together. To obtain the exact proportionality between the two generators the Pro-7/1200 modelling light has to be set at 1/2, as the flash energy is half of the Pro-7/2400. 28 [9] Connecting Camera & Flash Meter [11] [12] The two sync sockets [7] allow the camera and flash meter to be connected simultaneously. [. . . ] The generator automatically turns off when the controls MASTER [13], MOD. LIGHT [11] and the sync outlets have not been in use for 30 minutes. Photocell The built-in photocell [5] will sense flash release as well as IR-signals from most IR-transmitters. The photocell is disabled when the button marked SLAVE [7] is released. The photocell can also, via cable, trigger off an additional generator. [. . . ]
