Point the lumisphere at the camera (lens optical axis) from a position close to the subject and then measure. 1） Extending Lumisphere Rotate the upper part of the lumisphere retracting ring ② and fully align the ring mark with the extended symbol （）. 2） Retracting Lumisphere Rotate the upper part of the lumisphere retracting ring ② and fully align the ring mark with retracted symbol （）. Lumisphere Extended Lumisphere Retracted (flat) Extend lumisphere when measuring 3-D subjects such as people or buildings. Retract lumisphere when measuring flat subjects such as manuscripts, books, pictures, or when measuring lighting ratio (monitor function) (see P50 for details) or simply measuring intensity of illumination (see P28 for details). Caution ● Make sure the measurer does not influence the light measurement. (Do not block out light sources. Reflected light occurs due to the color of clothing. Take care not to let such reflected light enters Light Receptor Head.) ● If light meter is used with lumisphere retracting ring set at mid position, luminous intensity distribution characteristics will alter, resulting in inappropriate measuring. ● Do not push down the lumisphere with your hand. ● Keep lumisphere and Light Receptor Head clean and free of damage, as failure to do so may affect accuracy. When lumisphere becomes dirty, wipe clean with a dry, soft cloth. Never use organic solvent (thinner, benzene, etc.). Ring mark Extended （ ） Retracted （ ） ②Lumisphere ② Lumisphere

L-478D/L-478DR 40 5-2 Measuring in Flash Mode Measuring in Flash Mode refers to a measuring method that uses momentary light such as that produced by a flashlight or flash bulb. The following are the measuring methods used in Measuring in Flash Mode. ・Cord Flash Mode (connected) ・Cordless Flash Mode ・Cord Flash Accumulative Mode ・Cordless Flash Accumulative Mode ・Flash Radio Mode （for L-478DR only） ・Flash Radio Accumulative Mode （for L-478DR only） ※The following items explain Flash Radio Mode and Flash Radio Accumulative Mode. Also see 4-3 Setting Measuring Mode (P25) for details on changing measuring mode. 1) About Screen Display Details When flash light is measured, f-stop (a mixed value of fixed light and flash light = total intensity) is displayed on screen. Also, flash component ratio is displayed in numerical 10% increments against the total intensity. The respective measuring results of fixed light (orange) and flash light (blue) are displayed in the Analog Scale. 2) About the Analog Scale Touch the scale to turn the component ratio display ON or OFF. 3） Light Analyzing Function With a single measurement the ratio of flash light and fixed light are displayed. If flash light is measured, the measuring value will denote the total intensity (a mixed value of flash light and fixed light). Likewise, the component ratio display numerically shows in increments of 10% the ratio of flash light against the total intensity. This numeric value can be used to calibrate shooting to suit the artistic intention – for example, when shooting with a flash in a room lit by tungsten lamps, the tungsten lamp light (fixed light) can be strengthened or weakened (flash effect strengthened).

L-478D/L-478DR 46 5-3 Measuring with Radio-controlled Flash (for L-478DR only) 5-3-1 How to Measure Using Radio Control The measuring method using radio control involves connecting a radio receiver (sold separately) to the flash in order to trigger the flash from the main unit side. This enables one person to be able to measure the flash without the use of a synchro cord. The following are the modes that can be set to measure this way. ・ Radio Flash Mode ・Radio Flash Accumulative Mode Note that prior to measuring the Radio Control channels must be set. (See P51 for details.) ※ Radio receivers compatible with L-478DR: PocketWizard® series or other flash manufacturers that equip flashes with PocketWizard systems. Please read the manual provided with the radio receiver for details about operating the radio receiver. For compatible products, please see the LPA website (www.pocketwizard.com). Caution ● The controllable distance of flash-compatible radio systems varies in accordance with the position and direction that the radio receiver is set. To set the best parameters, be sure to set up the main unit and the radio receiver in the following way. 1. Make sure the main unit and radio receiver are visible to each other in a straight line. 2. Set up the radio receiver away from large metallic objects, concrete or objects containing a lot of moisture (people or wood, etc.). 3. Use Velcro tape or the tripod slot to secure the radio receiver. At this time, make sure the radio receiver’s antenna is fully above the power source box of the flash. In all situations, do not allow the radio receiver’s antenna to come into contact with metallic objects. 4. Depending on the location, there are cases when the radio receiver absolutely cannot receive a signal. The causes are varied and include radio waves being reflected off of nearby objects. Normally, this can be rectified by changing the direction of the radio receiver by several centimeters. Alternatively, check to see if the radio receiver is behind an object that absorbs or blocks radio waves, such as concrete, metal or low hill. 5. Under the above parameters, use radio control at a distance within 30 meters. 5-3-2 How to Measure with Radio Control Channels (1) How to Set a Radio Control Channel for Use The radio channels that can be used for measuring on this product are Standard Channels and Control TL Channels. Control TL Channel: Among the PocketWizard® products, this is a radio system that can control power (calibrate intensity). It has 20 channels. Each channel has three zones (A, B, C), which means that up to three flashes can be controlled by setting a zone.
L-478D/L-478DR 47 Standard Channels: Among PocketWizard® products, this is a radio system that only triggers flashes. It has 32 channels. Channels No. 1 to 16 are single channels.

Usage Precautions Caution ● To avoid damaging this meter, never drop it or subject it to shock. ● Avoid using it in water spray or rain as doing so may cause damage. ● Avoid storing it in high-temperature and/or humid locations as doing so may cause damage. ● Beware of condensation caused by sudden temperature change, as such condensation may cause damage or malfunction. ● If the temperature of the meter drops to -10 deg. C or beyond, response of the LCD becomes extremely slow and displays are difficult to read. At temperatures between 0 and 10 deg. C the LCD will become somewhat slower than normal but this does not hinder usage. Also, when the temperature exceeds 50 deg. C, the LCD will turn black and will be hard to read. This will return to normal when the temperature returns to normal. ● Do not place the meter in direct sunlight during midsummer or near heaters, etc., as the temperature of the meter will rise beyond that of the air temperature. Be careful when using the meter in hot locations. Maintenance Notes ● If your meter is splashed with water, wipe immediately with a soft dry cloth. Leaving the meter wet may cause rust or corrosion ● Keep the light receptor head away from dust/dirt and avoid scratching as accuracy may be affected. ● When light meter gets dirty, clean it with soft dry cloth. Never use organic cleaners (like thinner or benzene).
