3. Before Using 1. Attach the strap 1) Attach the Strap !5 by passing the small end loop through the strap eyelet !2 and passing the other end of strap through it. WARNING ● Please place in a location where an infant cannot reach and accidentally get the strap wrapped around his or her neck. There is danger of strangulation. 2. Inserting the battery 1) Requires type-AA 1.5-volt manganese dry cell battery (R6P) or type-AA 1.5-volt alkali dry cell battery (LR6) or type-AA 1.
3. Before Using 3. Checking battery capacity When the Power button q is ON, the battery power indicator on the LCD t is displayed. (Displayed) Battery power level is good. (Displayed) Battery power level is low. Have a spare battery ready. (Blinking) Replace battery immediately. REFERENCE: • If the liquid crystal display extinguishes immediately after the display appears when power is first applied, that is an indication that the battery is dead. Please promptly replace the battery.
3. Before Using 5. Auto Power OFF function 1) To conserve battery power, the meter will turn OFF about four minutes after last use. 2) Whether the Auto Power OFF function turns the power OFF or the Power button q is pressed, the settings and measured values remain stored in memory. When the Power button is pressed again the last settings are displayed. REFERENCE: • The power shuts OFF automatically after one minute when the power button is pressed and held. 6.
4. Basic Operation 1. Incident or reflected light measuring 1) To set for either incident or reflected light operation, slide the Lumisphere w mounting until it clicks. Incident light mode NOTE: Reflected light mode Setting operation ● Always use the Lumisphere mounting for setting. Hand operation of the Lumisphere may cause damage. ● The Lumisphere is an important light receiving unit. Please handle with care and try not to mark or soil. Wipe Lumisphere with a dry soft cloth if it becomes dirty.
4. Basic Operation 2) Interchangeably switch between EV mode and Shutter Speed Priority mode by pressing the Mode button e while holding down the ISO button i in Ambient mode. Measurement value also will be automatically calculated when a switch is made after measuring. MODE ISO REFERENCE: • Ambient light refers to continuous light like natural light (sunlight), tungsten lamps or fluorescent lamps. • Flash light is a brief, intense burst of light made by such as electronic flash units or flash bulbs.
4. Basic Operation 3. When set for incident light Incident light measuring is the measurement method that employs either the Lumisphere or Lumidisc functions. Measure with the lumisphere ai med in the camera direction at the position of the subject. 1) Using Lumisphere to Measure Lumisphere is used to measure people and buildings and other such solid objects.
4. Basic Operation 4. When set for reflected light Point the lens of the exposure meter toward the part of the subject to be measured from the camera position or from the camera direction and then measure. 1) This method is used to measure the brightness (luminance) of light reflected from the subject and is useful for metering subjects that cannot be approached or light-generating subjects (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.).
5. Measurement 1. Measuring Ambient Light In this measurement mode, we have the choice of shutter priority mode and EV mode. Press the Mode button e to select the Ambient mode. MODE 1-1 Shutter Speed Priority mode 1) Press the Mode button to select the Shutter Speed Priority mode. 2) Press the Up button y or Down button u to set the desired shutter speed. 3) Press the measuring button r to make 1/10 step measurement a measurement. Release the measuring value (f stop) button to complete measurement.
5. Measurement ✩ When the display range is exceeded, and E.o appears, press the Up button y to change the shutter speed to the high-speed side and thus enable an appropriate corresponding aperture value to be displayed. ✩ When the display range is exceeded, and E.u appears, press the Down button u to alter the shutter speed to the slow-speed side and thus enable an appropriate corresponding aperture value to be displayed. NOTE: • When brightness (or darkness) exceeds the measuring range of the L-308S, E.
5. Measurement 2) Press measuring button r to make a measurement. Release the measuring button to complete the measurement. The measured value (EV value) at that time will be displayed. While pressing the measuring button, the meter measures continuously until it is released. REFERENCE: Measurement value (EV) • EV (exposure value) is the reading that logarithmically expresses the constant quantity of light combined from the shutter speed and aperture value.
5. Measurement 1-3 Cinematography 1) Press Mode button e to select Shutter Speed Priority mode. 2) Press the Up button y or Down button u to select the cine speed for the camera that will be used. MODE The following cine speeds will be displayed after 1/6000 and 1/8000: 8, 12, 16, 18, 24, 25, 30, 32, 60 and 128 fs. The shutter angle that these speeds are based on is 180 degrees.
5. Measurement 2. Measuring Flash Light This measuring method comprises the cord and cordless flash modes. Measure the flash light to display shutter speed and aperture value (total amount of light combining ambient light and flash light) on the LCD. 2-1 Cord Flash mode This measuring methad is used to make sure synchronization with flash units, or to measure flash bulb by connecting Synchro cord. 1) Connect the flash synchro cord to the flash synchro terminal o on the exposure meter.
5. Measurement NOTE: ● There is a danger of electric shock if the meter is handled with wet hands, during rain, in areas splashed by water or where there is a lot of moisture, if you use cord flash mode. ● The electronic flash unit may trigger when you connect the synchro cord or operate the Power button. ● For flash unit with an extremely low trigger voltage, the flash may not fire. In this case, make measurements in auto reset cordless flash mode.
5. Measurement ✩ When the display range is exceeded (E.u), press the Down button u to change the shutter speed to the low-speed side, or raise the quantity of flash light and measure again to display a measurement value (aperture value). ✩ When brightness (or darkness) exceeds the measuring range of the L-308S, E.o (or E.u) will blink to indicate that measuring is not possible. In such cases please adjust the quantity of flash light and measure again.
5. Measurement 4) If the 90 second period is exceeded and the blinking mark stops, press the Measuring button again to return to ready to measure. 5) When the light from the flash is received, the measured value (f stop) is displayed. Even after measurement, the mode mark continues to blink and the meter is in ready state and a new measurement can be made.
6. Advanced Functions 1. Measuring Light Contrast This method is used to check studio lighting or lighting unevenness. 1) Mount the Lumidisc accessory (see page 8). 2) Turn ON just the main light source. Point the Lumidisc at the main light source from the subject position and then measure. 3) Next turn ON just the secondary light source. In this state now point the Lumidisc at the secondary light source and measure. EV Difference of Measuring Value Contrast Ratio １ ２：１ １.
6. Advanced Functions 2. How to use an incident illuminance (LUX or FC) meter 1) 2) 3) 4) Mount the Lumidisc accessory (see page 8). Set EV mode and ISO 100. Measure with the area to be measured parallel to the Lumidisc. Determine the illuminance (lux) from the calculation table using the measured EV.
6. Advanced Functions 3. Custom setting function POWER To match your camera, you can set the setting value and display value to full, 1/2 or 1/3 stop. MODE 1) To enter custom setting mode, hold down the Mode button e and turn ON the power button q. 2) Once custom setting mode is entered, the ‘CS’ for custom setting will be displayed in the ISO display area, and the setting number will be displayed in the aperture value display area.
7. Accessories ● Synchro cord (Sold Separately) This is a five-meter long cord with three plugs. An exposure meter, a camera, and a flash can all be connected at the same time. This is convenient when measurements are made, because it is not necessary to plug and unplug the synchro cord. Also one side of synchro cord has a look feature to make sure connection with the meter.

9. Safty Guide and Maintenance NOTE: ● To avoid damage to meter, never drop or subject it to shock. ● Avoid storping meter in places with high temperature and/or humidity. ● Be careful excessive temperature changes that could cause humidity and internal condensation, resulting in malfunction. ● If the temperature of the meter drops to -10°C or beyond, response of the LCD becomes extremely slow and displays are difficult to read.
