C-7000
Operating Manual
Please read the operating manual carefully to fully understand the features of this product
before use and keep it for future use. Keep the operating manual in a safe place.
Congratulations on your purchase of a Sekonic SPECTROMASTER C-7000.
Please read the operating manual carefully to properly utilize the many features and
benets of this precision instrument.
The Sekonic SPECTROMASTER C-7000 is a portable spectrometer equipped
with CMOS linear image sensor that can measure from 380nm to 780nm. Its large
color LCD, conveniently displays correlated color temperature, color rendering
index (CRI), chromaticity diagrams and color spectrum of various light sources.
The Sekonic C-7000 illuminance measurement complies with JIS Class A
standard making it a reliable illuminometer. Its capabilities make it suitable
for checking the quality of a light source during manufacturing and inspection
processes, as well as measuring the quality of light for various areas such as
ofce environments, construction sites, road lighting, and factory spaces.
In addition, the "C-700/C-7000 Series Utility", included as an accessory of this
product, can be used to save data, display measured values and graphs, and perform
settings when the meter is connected by USB to computers or tablets.

WARNING
●
I
nfants 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.
●
D
o not place batteries in open ames, attempt to short, disassemble or apply heat
to them, use unspecied batteries, or recharge them (except rechargeable batteries).
They may burst and cause res, serious injury, or damage to the environment.
●
Do not use the spectrometer in a place containing ammable or combustible
vapors. Otherwise, it may cause a re.
●
Exercise care not to drop uids on the spectrometer. Also, do not attempt
to insert metals into it. Doing so may cause a re or an electric shock. If any
uid drops on or a metal is inserted into the spectrometer, turn the power
switch OFF immediately, and remove the battery (or unplug the USB power
cable). Then, consult our Support Center for assistance.
●
Do not disassemble or modify this spectrometer. Doing so may cause a re
or an electric shock.
CAUTION
●
D
o not handle this product with wet hands, or leave it in the rain or in a location
where it may be splashed with water, submerged, or come into contact with moisture.
There is a danger of electric shock if the "Flash Light Cord (PC) Mode" is used.
This may also result in damage to the product.
●
Do not attempt to disassemble the product for modication or parts
replacement. It may affect measurement results or damage the meter.
●
Do not attempt to play the included CD-ROM using an audio CD player.
It may impair hearing or damage speakers and earphones.
●
G
ently tap the meter's LED panel when changing modes or making selections.
Using pointed pens or pencils may scratch the LCD screen or damage the product.
●
I
nfants 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 that the neck strap does not come loose when carrying the
product, as the meter may be damaged when dropped.
●
This neck strap is made of polyester ber.
Please refrain from using the product if synthetic bers cause your skin to
become irritated, inamed or itchy in order to prevent worsening your symptoms.
●
Do not measure a bright object that emits light exceeding the measuring
range (wavelength and illuminance). They may damage the optical
components and result in inaccurate measurement.
●
Before removing or replacing the battery or USB cable, always turn the
power switch OFF. Otherwise, the spectrometer may fail.
●
Do not place the product on an unstable or tilted bench. Otherwise, it may
drop and you may be injured.

NOTICE
●
A protective sheet is attached to the LCD. Peel it off before use.
●
Although the LCD monitor is manufactured to very high standards, it is possible to
observe a few dead pixels on the screen. This is normal and not a malfunction of the
meter.
●
Do not use at altitudes above 2,000m (6,561 feet).
●
Our company shall not be liable for any data loss caused by, but not limited to, malicious
acts and control errors.
●
You can install the software on the included CD-ROM only when you agree with all
articles in the license agreement that comes with the CD-ROM.
●
Be sure not to drop the meter or subject it to sudden impacts, as the meter will be
damaged.
●
Do not store the meter in areas of high temperature of high humidity, as the meter will be
damaged.
●
Be careful not to transport the meter from cold to warm moist conditions as condensation
will form on the meter and may damage it.
●
If the meter is operated in temperatures below -10°C, the response of the LCD will
greatly slow down and the display may be difcult to view and read. This will not harm
the meter. Also, if the temperature exceeds 50°C, the liquid crystal display will darken
and become difcult to read, but when it returns to room temperature it will return to its
normal condition.
●
If the meter is left in direct sunlight, a vehicle, or near a heater, the unit's temperature will
rise and may result in damage. Please be careful when using the meter in these types of
locations.
●
If the meter is left where corrosive gases may be generated, the gases may affect the
product and may result in damage. Please be careful when using the meter in these
types of locations.
●
In case of disposing the meter, follow the rules of disposal in your area.
Maintenance Notes
●
Be careful not to let the Light Receptor become dusty, dirty, or scratched as this may
affect the precision of the measurement.
●
If the meter becomes dirty, wipe it with a dry, soft cloth. Never use organic solvents such
as thinner or benzine.
NOTE
●
For used batteries, dispose of them according to the rules of your area, or bring them to
a battery recycling shop near you.

NOTICE
●
When taking measurements, the C-7000 should be located at a distance that is
approximately 10 times (10X) the diameter of the light source being measured.
●
When measuring the light source, be careful not to measure the light reected off
from ceiling, wall or oor because precesion of measurements may be affected.
●
Because the precision of measurements may be affected, be careful not to
damage or dirty the white surface of the Light Receptor 1. If the Light Receptor 1
becomes dirty, wipe it with a dry and soft cloth. Never use organic solvents such
as thinner or benzene.
●
There may be those who are sensitive to ash or other strong lights
(photosensitivity), and they may be negatively affected by light. Therefore, be
careful when people are nearby during measurement.

CAUTION
●
Do not trigger ash while skin or other objects are in contact with the ash
tube. Do not touch the ash tube after repeated ashes. (It may cause
burns.)
●
Do not trigger ash while near the eyes of people or animals. (It may
temporarily affect vision.)
●
The ash may be triggered suddenly. Because there is the possibility of
burns or negative effects on vision, please handle with care.
NOTICE
●
If the ash output power is too weak compared to the surrounding light, the
meter, when set in cordless mode, may not detect the ash output. In this case,
use "5-4 Measurement in Cord (PC) Flash Mode". (P69)
●
Pulsed light sources such as uorescent lights or special lighting could cause
the meter to take cordless ash measurements in rare cases. In these situations,
use "5-4 Measurement in Cord (PC) Flash Mode". (P69)
●
If the Light Receptor 1 detects a sudden and bright change in lighting
intensity, the meter may mistakenly take a measurement. To avoid this, take "5-4
Measurement in Cord (PC) Flash Mode". (P69)
●
Do not use Cordless Flash Mode for sources which gradually increase to peak
power, such as traditional ash bulbs, as they cannot be detected and measured.
Be sure to take "5-4 Measurement in Cord (PC) Flash Mode". (P69)
●
When using Cordless Flash Mode, the LCD screen illumination dims during
measurement, and the LCD is illuminated for 3 seconds after measurement. To
cancel standby mode, touch the screen or press the Menu Button 6.
●
In the Cordless Flash mode, the measured color temperature may change
depending on the shutter speed set for ash measurement and the amount of
ambient light present when the measurement is made.
NOTE
●
When using the meter in Cordless Flash Mode, it is possible to mount the meter to a
light stand, tripod or similar support using the Tripod Socket 0.
●
[Over] or [Under] will be displayed if the light source illumination is too bright or not

●
Do not handle this product with wet hands, or leave it in the rain or in a
