Your SIXTOMAT flash is an exposure meter with digital display from GOSSEN. It measures continuous light and flash, and it covers a wide measuring range with great accuracy. A wealth of knowledge in the area of light metering, based on many decades of experience in the manufacture of exposure meters, is now being made available to the user, in the simplest manner possible, through microprocessor technology.
1 Display 1.
1.2 Display duration The display is automatically shut off, i.e. there are no readings, if any control button of the SIXTOMAT flash has not been used for 2 minutes; the readings are stored. – The stored values are recalled by depressing the function or value buttons – Renewed measurement is instantly possible when the metering button is depressed. The values of the last meter reading are stored until a new meter reading is taken.
Self-Checking routine 2.2 Incident and reflected light measurement With regard to its measuring possibilities and operation, the SIXTOMAT flash was designed for professional use. Due to its adjustable diffuser dome, the meter is easily adapted for the dedicated amateur and the professional photographer. The microcomputer performs a self-checking routine as soon as the battery has been inserted. Every possible display segment appears on the display during this routine.
Measurement by the incident method is far more accurate and reliable to establish the correct exposure setting than the calculating of a mean value obtained with the reflected light measurement in your camera. In the latter case, the reading depends upon the range of contrasts of the subject. However, there is not always a uniform distribution of bright and dark areas of equal importance within the subject. Incident light measurement is also imperative with inaccessible subjects.
3 The individual functions 3.1 Setting the film speed – Select ISO with the function buttons – Adjust the required ISO value with the value buttons (display left: DlN value, right: ASA value) Once the film speed has been set, it is transferred to the memory of the SIXTOMAT flash when the meter is adjusted to any operating function, and remains visible on the top right-hand side of the digital display. Any change of the film speed directly influences the stored paired aperture and shutter values.
3.2.1 Flash readings Readings can be taken with or without synchronizing cable. When used in conjunction with a synchronizing cable the flash is fired by depressing the M button – the flash is automatically fired and measured. – Select with the function buttons – Adjust the desired synchronizing speed with the value buttons. Synch range from 1 s to 1/1000 s (including 1/90 s) – Depress the measuring button M .
3.2.2 Multiple flash Occasionally the light output from a single flash may not be sufficient to enable you to work at the aperture desired. When this happens, simply push the top value button until the desired f/number appears in the display. The digital shutter speed display disappears, to be replaced by information on the number of flashes that have to be fired for the desired f-stop (e.g.: F4 = 4 flashes). The SIXTOMAT flash will calculate up to a maximum of 10 flash sequences.
3.2.4 Contrast measurement 3.2.5 Aperture priority mode – Select t with the function buttons – Keep the measuring button M depressed while aiming the meter at various areas of the subject. The analog aperture scale displays the f-stop series between two extreme values, and with the actual measured value flashing. The first measured f-stop is displayed on the left-hand side of the display (it remains displayed as a reference value (e.g. of a grey card)).
3.2.6 Exposure value EV 3.2.7 CINE scale (frames per second) – Select EV with the function buttons – Measure by pressing the meas. button M – The measured exposure value appears on the left-hand digital display (accuracy: 1/10 stops), and the aperture as a rounded-off mark in the analog aperture scale – Select with the value buttons other paired aperture/shutter speed values corresponding with this exposure value. – Select t with the function buttons – Select the desired Cine speed (f.p.s.
The displayed aperture applies to a 180° shutter blade. Enter a COR value in the function COR for other shutter blades as an extension factor. V = 180°: open aperture angle 3.3 Measurements outside the measuring range – The SIXTOMAT flash will not produce any useful readings outside its measuring range – If it is too dark or too bright, an E (= Error) appears on the left-hand digital display, and alongside it for too dark, or for too bright 14 3.3.
3.4 Setting and measuring correction values (see Section 3.4.4 Important remarks concerning correction values, page 17) The extension factor is shown in the right-hand digital display, and the correction value in stops in the left-hand section. 3.4.1 Setting correction values Enter in 1/10th stops (small figure) within a range of ±7.9 exposure value stops. A figure preceded by „–“ indicates an exposure extending correction. Example: –3.1 stops equal factor 8.6.
3.4.2 Measuring correction values Insert the light-reducing filter (e.g. neutral density filter) in the optical path, and press the measuring button. The light reducing factor in stops, and the extension factor, automatically appear on the display. Pressing the function buttons transfers the correction values to the memory of the SIXTOMAT flash. The box around COR still appears when a corretion value was entered. Correction values can also be directly measured.
3.4.3 Cancelling correction values – Select COR with the function buttons – Press measuring button (display rF --) – Select any other function with a function button – Correction value is cancelled, and the box around COR disappears 3.4.4 Important remarks concerning correction values The SIXTOMAT flash is a precision meter calibrated with great accuracy to provide exact exposure data.
We recommend the following procedure: Take the readings of a few normal subjects with the utmost care by the reflected and incident light measuring methods, and take five shots of each subject on colour reversal film. The first picture should be exposed with the exposure settings supplied by the SIXTOMAT flash. The exposure settings for the remaining shots are then increased and decreased, respectively, by half an f-stop and then a full f-stop. Make a note of the shooting conditions.
