3. Before Use

●

Before Use

3-1 Attaching the Strap

Pass the strap (included) through the

outer hole of the Strap Eyelet.

Pass the opposite end of the strap

through the loop at the end of the strap.

WARNING

●

Infants or toddlers may accidentally wrap the strap around their neck,

so please place it in a location out of their reach. There is a danger of

suffocation.

CAUTION

●

Infants or toddlers may accidentally grab the strap and swing the product, so

please place it in a location out of their reach, as the meter may be damaged

by impacts.

●

Be careful not to let the strap become entangled when carrying the meter.

Otherwise, the meter may be damaged due to an impact shock that may

occur when the meter is dropped, etc.

●

This strap is made of polyester ber.

The synthetic fabric has caused skin irritation, redness, or itching. If you

experience this, discontinue using strap.

3. Before Use

●

3-2 Inserting the Batteries

Prepare a single AA battery.

Slide down the battery compartment

cover in the direction of the arrow to

remove.

Insert the battery observing the polarity

with the +, - marks in the battery

compartment.

Align battery compartment cover with

main unit and slide shut.

Make sure that the cover is properly in place and closed.

WARNING

●

Never place batteries in re, short, disassemble, heat or charge them. The

batteries might break down, and cause an accident, injury or pollute the

environment.

CAUTION

●

Use the manganese or alkaline batteries.

●

Please insert the battery minus “-” side first. When removing the battery,

remove them plus “+” side rst.

●

lf the meter will not be used for an extended period of time, it is

recommended to remove the batteries to avoid possible damage caused by

battery leaking.

3. Before Use

●

3-3 Power ON/OFF

Power ON

Press the POWER Button.

Power OFF

Press and hold the POWER Button in for

1 second or longer and the meter will turn

off.

NOTICE

● Please wait 3 seconds between repeated power on and off sessions.

NOTE

● If the LCD screen shows no display, check if the batteries are installed properly (Pos/Neg

positioning) and have enough capacity.

● All settings and measurements made during use are saved in memory even after the

meter is powered off.

3-4 Auto Power OFF Function

To save battery capacity, the meter will automatically turn off 4 minutes after the last

button is pressed.

NOTE

● All settings and measurements are saved in memory even

after the meter has

automatically turned off. When the power is turned ON, they will be displayed again.

● If, while in transport, the POWER Button is inadvertently and continually pressed in, the

meter will turn ON for about 1 minute and then automatically turn OFF to save battery

power.

3. Before Use

●

3-5 Checking the Battery Capacity

When the meter is turned ON, the battery power indicator on the LCD is displayed.

(Displayed) Battery power level is good.

(Displayed) Battery power level is low. Have a spare battery ready.

(Blinking) Replace battery immediately.

［

Liquid Crystal Display

］

NOTE

● When the meter is turned ON and the LCD screen appears and immediately turns off,

this indicates that the battery is depleted and should be replaced immediately. Having

spare batteries on hand is recommended.

● When the meter is continuously used at room temperature, the battery life is as follows.

(based on our testing condition)

Manganese: 10 hours

Alkaline: 20 hours

3-6 Replacing Batteries

●

Always turn off the power before replacing batteries.

If you replace batteries while the power is turned on, the measured

values that are obtained during operations are not saved. Also, this

may cause a failure.

●

If an unexpected display appears on the LCD during battery replacement

or measurement, i.e. settings other than selected, or if the meter does

not respond when a button is pressed, remove the batteries, wait at least

10 seconds, and then re-install them.

4-2 Incident and Reected Light Measurement

To set for either incident or reected light operation, slide the Lumisphere mounting until it

clicks.

Incident light Mode Reflected light Mode Setting operation

Mounting

NOTICE

● Always use the Lumisphere mounting for setting.

Hand operation of the Lumisphere may cause damage.

（

Lumisphere and mounting can

not be removed.

）

● 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. Never use

organic cleaners (like thinner or benzene) to clean Lumisphere.

4-2-1 Incident Light System

The incident light system measures the light that is falling

on the subject using the Lumisphere or Lumidisc.

Point the Lumisphere at the camera lens (lens optical

axis) from a location close to the subject, then make a

measurement.

Using Lumisphere

Lumisphere is used to measure the light that illuminates

people and buildings and other three-dimensional objects.

Measurements are made at the subject position aimed in

the direction of the camera lens.

Incident light Mode

4. Basic Operation

●

Using Lumidisc (Optional Accessory)

The Lumidisc is used to measure the light falling on green-screen walls, paintings or at

art. It is also used to adjust lighting ratios with multiple light sources (

➡

P28) or when

taking Lux and Footcandle measurements (

➡

P24,

➡

P27). To measure light with

the Lumidisc, slide the Lumisphere mounting to the right (same as if measuring reected

light), then insert, at an angle, section B of the Lumidisc into slot A of the meter body and

press down on the strap eyelet C to secure the Lumidisc.

Slot A

Strap eyelet C

Section B

Slot C

The Lumidisc is removed in reverse order to the mounting method.

At this time the strap eyelet of the Lumidisc should be pulled up and away

from the meter body.

WARNING

●

Keep the Lumidisc

(

Optional Accessory

）

out of reach of Infants or toddlers,

as swallowing such objects can cause suffocation.

NOTICE

● Be sure to handle the Lumidisc correctly to prevent damage that may occur if mounting

or removal is incorrect.

● When the Lumidisc is not being used, do not attach it at the right of the Lumisphere for

storage. This will block light falling on the Lumisphere and affect the accuracy of the

measurement.

● The Lumidisc is an important light receiving unit. Please handle with care and try not to

mark or soil. Wipe Lumidisc with a dry soft cloth if it becomes dirty. Never use organic

cleaners (like thinner or benzene) to clean Lumisphere.

4. Basic Operation

●

4-2-2 Reected Light System

Switch the light receiving method to the reflected light

system to make a measurement. The reflected light system

measures the brightness (luminance) of the light reflected

from the subject. It is useful to meter distant objects such as

landscapes, if you cannot go to the location of the subject, or

to meter subjects that generate light (neon signs, etc.), highly

reflective surfaces, or translucent subjects (stained glass,

etc.).

To take a reected-light measurement, hold the meter in front

of the camera and point the metering lens toward the part of

the subject you want to measure. If the subject area is small,

you may have to move the meter closer to the subject to

measure it properly.

NOTICE

● As the reected-light lens has a 40-degree view, measurements made from the camera

position will often result in an average of all subject tones.

● To measure only part of the object, move the meter as close as possible to the part of the

subject you want to measure. Take care to position the meter so that it does not cast a

shadow onto the part of the subject you want to measure.

● The lens is an important light receiving unit. Do not touch the lens or allow it to become

dirty. Wipe the meter lens with a dry soft cloth if it becomes dirty. Never use organic

cleaners (like thinner or benzene) to clean the meter lens.
