CL-70F
Operating Manual

Congratulations on your purchase of a Konica Minolta CRI Illuminance Meter CL-70F.
Please read the operating manual carefully to properly utilize the many features and
benets of this precision instrument.
The Konica Minolta CRI Illuminance Meter CL-70F 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 Konica Minolta CL-70F 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
ofce environments, construction sites, road lighting, and factory spaces.
In addition, the "CL-70F 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 unspecied 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 modication 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, inamed 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

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 difcult 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 difcult 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.
●Insulate plus and minus terminals with tape or other insulation material.
●Do not remove the covering material of batteries.
●Do not disassemble the batteries.
