User manual METZ MECABLITZ 34 AF-3 P

[. . . ] In the event of flash shots with full light output observe an interval of at least 3 minutes after a series of 20 flashes. â· NEVER place material that is impervious to light in front of, or directly on, the reflector screen. The high energy of the flash light will burn the material or damage the screen if this is not observed!There are no components inside the flashgun that can be repaired by a layperson. [. . . ] The mecablitz transmits different signals and messages to the camera when it is connected to the camera and is switched on. 1 Flash-ready indication The green light on the mecablitz illuminates when the flash capacitor is fully primed, thereby indicating flash readiness. the flash readiness signal is transmitted to the camera where it is indicated by a corresponding display in the camera's viewfinder. Depending on the selected operating mode, the camera is changed to flash sync speed when flash readiness is reached. The flash will not be fired if the shutter is released before the flash ready light illuminates with the result that the exposure may be incorrect if the camera control circuit has already changed over to flash sync speed. 2 Automatic flash sync speed control Flash readiness has the following effect on system cameras: Effect: Camera mode: Programmed auto exposure mode [P]: Camera changes to 1/30 - 1/250 sec. As in [P] Aperture priority mode[Av]: Shutter priority mode [Tv]: Shutter speeds can be set on the camera that equal or are slower than the sync speed. Manual mode [M]: As in [Tv] Note: If (independent of the operating mode) a shutter speed faster than the flash sync speed is set on the camera, the camera will automatically change to flash sync speed when flash readiness is reached. 4 Information displayed in camera viewfinder when flash unit is switched on Displays in viewfinder Meaning prior to shutter release not illuminated Flash unit not yetready for firing or blinks slowly permanently illuminated Flash unit is ready for firing Warning with SF1/SFx: is illuminated in the camera's viewfinder but the flash is not triggered when the shutter is tripped. The camera has activated the triggering lock because the ambient light is too bright. Displays in viewfinder Meaning prior to shutter release blinks quickly Flash was sufficient for correct exposure not illuminated or Flash was insufficient. 4) The red correct exposure light briefly illuminates when flash exposure was correct. The mecablitz receives its information exclusively from the connected TTL-controlled AF-camera. exposure measurement in TTL mode (TTL = through-the-lens) is completed by the camera's sensor. This sensor measures the light reaching the film through the camera lens. An electronic control circuit within the camera transmits a stop signal to the flashgun as soon as the film has been exposed by the correct amount of light; the flash is then instantly cut out. The advantage of the TTL mode is that all factors influencing the exposure of the film (such as filters, change of aperture or variable aperture zooms) are taken into account. Spot , matrix or centreweighted overall readings) offered by some cameras. [. . . ] Turn the attachment clockwise and insert the guiding edge into the case gap. 7: Mounting and removing the attachments To remove turn the attachment beyond the retaining spring (see fig. Forming the flash capacitor The flash capacitor incorporated in the flashgun undergoes a physical change when the flashgun is not switched on for prolonged periods. 10 minutes every 3 months and to fire a few flashes The batteries must supply sufficient power to light up the flash-ready light within one minute after the flashgun was switched on.
