Liquid Crystal Display (1) b.c. mark (battery check) is displayed when the meter is switched on. (2) Digital value of the measured F-stop or EV is shown (f/1~ f/90 or EV(- 1) ~ EV25), when the meter is used in T-priority mode. (3) F-stop value is set in F-priority mode for ambient light measurement. (4) E.u. (underexposure) or E.o. (overexposure) mark is displayed when the measuring range is exceeded. Any of the following symbols is displayed depending on the mode selection.
Mode Selection and Operation Reference Table 6 7
Accessories 1. Lumisphare 3. Reflected-light filter Use Lumisphare when you wish to measure incident light for portraits and three-dimensional subjects. Use Reflected-light filter when you wish to measure the reflected light (brightness) of subject. Use it to calculate the relative brightness ratio (illumination contrast of subject) for adjusting lighting balance, or when it is difficult to take incident light measurement.
Preparing the Meter for Operation 1. Insert the batteries DIGI MASTER requires 2 pcs of AA size pen-light battery (1.5V x 2). (1) Open the battery chamber cover by sliding it in the direction of arrow. (2) Insert the batteries carefully aligning (+) and (-) polarities as indicated inside the chamber. (3) Replace the cover by sliding it and inserting its notch into the slot of the meter. (3) DIGI MASTER is equipped with auto shut-off function.
(3) In the ambient light mode, (a) T-priority measurement or F-priority measurement can be selected by pressing the F/T selection key (Fig. 7). 4. Setting ISO sensitivity Press either side of UP/DOWN key while depressing ISO key. Film speed (ISO sensitivity) can be set within the range of ISO 3 ~ ISO 8000 (Fig. 9). The set value of ISO sensitivity is memorized even if the meter is switched off or the measuring mode is changed. 5.
Wireless (cordless) Measurement using Electronic Flash Unit 6. Display lighting DIGI MASTER is equipped with a background illumination for LCD. Electro luminescence ''ECLAT" illuminates the LCD while the display-light key (D.L.) is depressed (Fig. 12). In case the photographing subject is too far to use synchro cord, or in case the synchro cord disturbs photographing, flash light can be measured without connecting the cord.
Wired Measurement using Flash Unit with Synchro Cord Cumulative Measurement using Electronic Flash Unit Wired measurement is recommendable when you measure the flash light from the subject position, or when the meter fails to register flash light in wireless (cordless) measurement; for example, close to a fluorescent lamp, or in high ambient condition, and so forth.
Ambient Light Measurement Measuring ambient light, whether it is daylight or standard electric light, is a fairly simple matter using either incident or reflected light method. • F-priority and T-priority can be converted by pressing F/T selection key (Fig. 25) (2) Set the film speed (ISO) and shutter speed (in T-Priority mode) as shown in the paragraphs for “Preparing the Meter for Operation”. When you use the meter in F-priority mode, set the film speed (ISO) and F-stop value.
Memory Display Function DIGI MASTER is equipped with a memory function for measured 2 F-stop values. This function is usable for both wireless (cordless) and wired measurements for a single flash light as well as ambient light measurement in T-priority mode, but not for cumulative flash measurement. (4) Memory mode is released by pressing the memory-off key (Fig. 30). (1) After measurement, press the memory key. The measured F-stop value is memorized and displayed in bar dot symbol (Fig. 27).
Post-Measurement Calculation (1) Post-measurement calculation by changing ISO sensitivity By changing ISO sensitivity the measured F-stop value is automatically changed to the appropriate one corresponding to the changed ISO value (Fig. 31). This calculation is applicable to all measuring modes, both flash and ambient light measurement.
Contrast Metering for Lighting Balance Illuminance (Lux) Measurement When calculating a desired lighting balance, DIGI MASTER can be used to measure the brightness of main and fill-in lightings from the subject position. DIGI MASTER can be used as an expendient Lux meter when used with the Lumidisc in ambient light measurement mode. (1) Mount the Lumidisc instead of Lumisphare for usual incident light measurement.
Adjusting the Balance of Meter Care of the Meter While every effort has been made to ensure the most accurate standard calibrations as applied by SEKONIC for your DIGI MASTER, provision has been made for an adjustment of approximately ± 1EV by correcting the setting of the dial on the underside of the swivel head. It is recommended that you test the meter fully in actual photographic conditions before adjusting it to suit your preference.
