Thank you for purchasing our Litemaster Pro L-478D/L-478DR.
Please read this Users’ Manual thoroughly in order to become acquainted with the light meter and
thus be able to use it safely and correctly.
The Litemaster Pro L-478D/L-478DR (referred to as L-478D/L-478DR from here on) comes
with “color exposure profile” and “EV scale” functions that are highly compatible to digital
cameras. What is more, it is a light meter packed with exceptional functions to deal with
images and all sorts of filming intentions that require systems such as spot measuring,
incident light measuring, flash measuring and partial metering. The L-478D/L-478DR makes
outstandingly accurate measuring across a wide range come true in all shooting scenarios,
whether they be outdoors or in.
Using in advance the latest Data Transfer Software※1, you can set your camera exposure
profiles※2 in the L-478D/L-478DR (profiles for up to ten cameras). And, by calling up these
settings when you need them, you can measure exposure accurately. Moreover, when
metering light, you can check in an instant whether or not the subject is in the exposure
range. Additionally, you also can make user and Custom Setting Function at the Data
Transfer Software side.
※1 Data Transfer Software is provided on the CD-ROM. To use this software, you will need to install it onto your
computer and connect it to L-478D/L-478DR via a USB cable. Please see the Users’ Manual on the CD-ROM for
operating details.
※2 Exposure profile is the information denoting the characteristics of your digital single-lens reflex. (This is
information such as sensor and circuit characteristics that occur for digital single-lens reflex, or the exposure
tolerance and exposure range (reproduction field and tolerance range) that occur for film characteristics of a silver
halide camera. First, authenticate the information by test shooting and then create exposure profiles using the
Data Transfer Software.

● When there is no battery power, and the power is turned ON, the screen may appear and then
abruptly close, but this does not mean the main unit is damaged. Please insert new batteries. We
recommend that you have spare batteries ready at all times.
● With consecutive measuring, the battery lifespan for this product at room temperature is
approximately ten hours (Sekonic test conditions for alkaline batteries).
● The batteries packed with the product at time of purchase may have a shorter lifespan.
2-5 Cautions about Battery Replacement during Measuring or the
Use of Memory Function
1) Always turn OFF the power before replacing batteries.
2)If an abnormal display (one that has not been set, etc.) appears on the LCD after battery
replacement or during measuring, or the light meter will not operate even when an operation
button is pressed, remove the batteries, wait ten seconds or longer and then reinsert them.
2-6 Auto Power OFF Function

4-2-1 Measuring with Incident Light Function (Lumisphere/Flat)
Use either extended or retracted (flat)
lumisphere to measure incident light. 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.).

4-2-2 Measuring with Reflected Light System
When changing the light receiving system to the reflected light
system for use with this main unit, detach the lumisphere,
and attach a viewfinder (sold separately).
The reflected light system involves measuring the
brightness (luminance) of light reflecting off of the subject.
This method is suited to measuring subjects that cannot
be approached closely, or light emitting subjects (neon
signs, etc.) or light-transmitting subjects (stained glass,
etc.). From the camera position and from the same
direction as the camera, correctly point the light meter
lens at the part of the subject to be measured and take
measurement.
※ See viewfinder manual for details on attaching
viewfinder (sold separately).
1) Detaching Lumisphere
Hold down the lumisphere lock lever ①, take in hand both
the upper and lower rings comprised in the lumisphere
retracting ring and turn them anticlockwise to detach the
light receding unit.
2) Attaching Lumisphere
Align the mark on the lumisphere retracting ring ②
with the mark on the main unit, press the Light
Receptor Head into main unit and then turn to the right
until you hear a clicking sound.
※ Check to see that the lumisphere lock lever ① is
sitting up.
Caution
● When attaching/detaching lumisphere or viewfinder, be sure not to touch the light receiving
element on the main unit side.

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).

Cord Flash Mode (P34) for details on how to measure.
● Under rapid-start fluorescent lamps or special lighting equipment, on rare occasions such
lighting will be judged as flash light, and measured as such. In such cases, see 5-2-1
Measuring in Cord Flash Mode (P34) for details on how to measure.
● Even if the flash is not triggered during measuring standby status, a sudden change of light in
the Light Receptor Head may cause a measurement to be taken. To avoid this, see 5-2-1
Measuring in Cord Flash Mode (P34) for details on how to measure.
● As the triggered light waveform of a flash bulb is gentle, light will not be detected in cordless
mode. Therefore, be sure to see 5-2-1 Measuring in Cord Flash Mode (P34) for details on

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. And, channels No. 17 to 32
are multi channels. Each channel has four zones (A, B, C, D) that can be set, which
means that up to four flashes can be controlled by one channel.

6-5 Filter Compensation Function
By registering and setting the filter compensation value in the light meter, measuring results
that reflect the compensation value can be obtained.
This is a useful function for measuring exposure when a filter is being used on the camera lens.
Again, when deciding exposure using the highlight standard or shutter standard, having each of the
compensation values registered in advance is useful.
The setting range of the filter compensation value is ±5.0EV.
The following are the three types of filter compensation that can be selected.
1) Filter compensation value setting (Input numeric value. The icon will be displayed at
the top of the screen.)
2) Selection of a filter name that has been registered in advance

7. Separately Sold Accessories
・ Synchro Cord
This is a three-way, five-meter long cord that sync
connects light meter, flash and camera, which is great
because there is no need to replug cords when shooting.
Also, one of the synchro cord’s connectors has a locking
mechanism to prevent disconnection.
(Cord has two male connectors and one female one.)
The connector with the lock function is a male one.
・Standard Gray Card
This is a gray card (110mm x 102mm) with 18% reflection
ratio. 1
With this card, you can check the standard measuring value
during shooting.
By using the standard gray card to determine standard
exposure for results of measuring, you can acquire the
exposure data that will provide faithful color reproduction.
・Exposure Profile Target
This is the test chart (260mm x 160mm) used to create
camera exposure profiles. The front features nine types of
gray patches including black and white ones, while the
rear is 18% gray card, so it can be used to determine
white balance for digital cameras and exposure with the
reflected light system.
・Exposure Profile TargetⅡ
This is the test chart (350mm x 120mm) used to create
camera exposure profiles. The front features 25 types of
gray patches including white and black ones, while the
rear is 18% gray card, so it can be used to determine white
balance for digital cameras and exposure with the
L-478D/L-478DR
81
reflected light system.
・Viewfinder 5°
This is a viewfinder with a five degree acceptance angle.
When measuring with the reflected light system, remove the
lumisphere and attach the viewfinder. When a subject
cannot be approached closely, point the viewfinder lens
correctly at the part of the subject to be measured and
make the measurement. (See P29 for details.)

10. 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).
