Operating Manual

Congratulations on your purchase of a Sekonic SPECTROMASTER C-700/C-700R.
Please read the operating manual carefully to properly utilize the many features and
benets of this precision instrument.
The Sekonic SPECTROMASTER C-700/C-700R is the rst spectrometer that
measures every light source (LED, HMI, Flourescent and the natural light
spectrum) PLUS wireless ash (C-700R only). In addition, with its CMOS linear
image sensor, the SPECTROMASTER C-700/C-700R makes it possible to
create output wavelength in 1 nm increments, capture spikes in light source
output, especially uorescent and LED lighting, and provide unmatched color
measurement accuracy.
In addition, the "C-700/C-7000 Series Utility", included as an accessory of this
product, can be used to save data, display measurement values and graphs, and perform
settings when the meter is connected by USB to computers or tablets.

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.

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 disassemble the batteries.
