Flash measurement without cord Flash measurement with cord mode symbols are switched in the following sequence: 8 Aperture/EV/Battery/Others “b.c” Battery capacity z:‘$ See Page 5. Aperture value (Indicated by a number and dots $“; ) Exposure value (Indicated by a number and dots $‘$ ) See Page 7. E.u Under exposure E.
3. Mode Selection Your L-308Bll can measure both incident and reflected light in both ambient light and flash light (electronic flash or flash bulb) modes. You can switch the modes as follows: [Ligh&y.eng [Ligh$xec#ng [Measured light] [Mode/display method] see Page 7. 3.1 Switching between incident light metering and reflected light metering Slide the lumisphere and stop it at the clicking position of “a” or “b” (See Fig.1 and 2). 5 Lumisphere b Fig. 1 Incident light metering Caution: 3.2 Fig.
4, Light-receiving Method 4.1 Incident light metering Hold L-308BII close to the subject, point the lumisphere towards the camera, and measure the incident light intensity, (Fig. 8) ;Q,, //// II Fig. 8 Caution: Do not fit the Lumidisc next to the Lumisphere when you take incident light metering. Otherwise, the Lumidisc will affect the exposure in proper reading. 4.
5. Preparation for Measurement 5.1 Inserting the battery Use a 1.5-volt, type-AA battery. Use a manganese dry cell (R6P) or an alkaline one (LR6). Never use any of other types. 0 To remove the battery case cover simply slide it in the direction of the arrow. 0 Insert the battery in the battery case aligning the polarities as indicated on the inside of the case. (Fig. 10) 8 Slide the battery case cover along the unit to close it. Check that the cover is securely closed. 5.
0 If you press the mode selector in the ambient light measurement mode while holding down the IS0 button, the display is toggled between EV and F values (Fig. 12 and 13). If it is toggled after measurement, the measurement data is automatically recalculated and redisplayed. NOTE Fig. 12 5.5 Fig. 13 Setting up film speed (ISO) 0 Press the IS0 button, and a film speed value is displayed (Fig. 14). @ Set up the film speed by pressing the Up or Down button while holding down the IS0 button.
6. Ambient Light Measurement 6.1 Mode Selection 0 Press the mode selector to enter the ambient light measurement mode. 0 Set up the film and shutter speeds. @ Press the measuring button, and the aperture value is displayed (Fig. 17). Fia. 17 0 Fig. 17 shows the shutter speed 1/125, and aperture F2.0+3/10 measured. l In the ambient light measurement mode, light measurement is continuously conducted while the measuring button is kept depressed.
7.. Flash Measurement with cord 7.1 Setting up of the flash measurement with cord and making measurement in this mode 0 Press the mode selector to enter this mode (Fig. 21). @I Set up the film and shutter speeds. Fig. 21 Caution: l l Set up the shutter speed which has been already set up on your camera. If you measure the flash bulb light, make sure that the shutter speed set is within the synchronizing range. 0 Connect the synchro cord to the L-308Bll’s synchro terminal (Fig. 22). B c--- J \F Fig.
8. Flash Light Wireless Measurement (Measurement without using the syrchro cord) 8.1 Flash light wireless measurement (1> Press the mode selector to enter this mode (Fig. 24). @ Set up the film and shutter speeds. Fig. 24 Caution: Set up the shutter speed which has been already set up on your camea. 0 Press the measuring button. After releasing it, mark blinks showing that your L-308BII is in a stand-by mode (Fig.25); this holds for about 90 seconds.
ow to use the Lumidisc How to measure light contrast 9.1 @) Fit the Lumidisc on the light receiving part. See page 3 ‘3.2 How to fit the Lumidisc’. @ Select the light mode you are going to use with the mode selector. @ Hold the L-308BII close to the subject and point the Lumidisc toward the main light source (turn off the auxiliary light source). Take reading. @I Keep holding the L-308BII close to the subject and point the Lumidisc toward the auxiliary light source (turn off the main light source).
