[. . . ] Otherwise, the Lumidisc will affect the exposure in proper reading. 4. 2 Reflected light metering You can meter the reflected light of the object by pointing the L-308Bll's lens at the object from the camera's position. 9 Caution: If you measure from the camera position, the entire object is measured in average. If you want to measure only a part of the object, do it at as close a position as possible to the part measured. Take care so that the part measured may not be shadowed by the meter, etc. 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). 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. 10) 8 Slide the battery case cover along the unit to close it. Check that the cover is securely closed. 5. 2 Battery check Depress the POWER button, and the LCD panel ("b. c" message and bar marking $`i) displays the current battery level. The battery level is indicated by a number of bars for one second. Then, the LCD panel automatically switches to the normal measurement mode. piii?iq NOTES l l You can sustain battery level display by holding down the Power button. When the battery level is indicated by only two or three dots, prepare a new battery. When the battery capacity drops below the limit, the "b. c" display blinks and then disappears. 5. 3 Auto Power-off To save battery capacity, the L-308Bll is automatically turned off (and all readings are erased) 4 minutes after your last operation. Press the mode selection button to select the desired measurement mode. Mode switching sequence: a Measurement mode Measurement mode with cord - ---II Measurement mode without cord 5 NOTE 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. If it is toggled after measurement, the measurement data is automatically recalculated and redisplayed. Fig. 13 5. 5 Setting up film speed (ISO) 0 Press the IS0 button, and a film speed value is displayed (Fig. @ Set up the film speed by pressing the Up or Down button while holding down the IS0 button. 14 button, the speed increases; if you press the Down button it decreases. If you hold down the Up/Down button for more than one second, the speed changes continuously. NOTE l You can set up the film speed either before or after measurement. 5. 6 Setting up shutter speed (T) Set up the shutter speed used by pressing the Up or Down button (Fig, 15). [. . . ] EV to lx conversion table (Example) If you read EV9 $1 _, the approx. illuminance value is 1800lx. 10 10.
