1.1 Features
MK350S Premium handheld Spectrometer Keeps the excellent designs and mul-funconal
user friendly operaon mode. Beside, it enhances the abilibty of LUX dynamic range from
100k lx to 150k lx. Auto dark calibraon is embedded to reduce the noise interference from
each temperature and lighng environment changes. Also, Cosine receiving surface is
opmized to conform with both JIS AA and DIN B Illuminance Meter class. Overall, it’s the
professional instrument with the cerficated accuracy and measuring speed.
Light source measuring funcons supersede the last generaon model (MK350S) with
outstanding performance. Users can choose from more than 40 light measurement units
(CCT, LUX, CRI, CIE1976, CIE1931,PPFD & PFD, CQS, Duv, LambdaP, S/P rao, TLCI, GAI and
others) to create their customized list. For further analysis and research, MK350S Premium
Spectrometer added "Flicker and Blue light Hazard" assessment funcons which can make
you measure light more producvely.

1.4 Annual Product Calibration
As the product is a high-precision instrument, please use it cauously. To ensure the
accuracy of measurements, annual calibraon is recommended. Please consult the agent or
the customer service department for the calibraon service.

Precautions / Warnings
Please read the following precauons to avoid fire, excessive heat, chemical leakage and
explosion :
■
■
■
■
■
■
■
■
■
MK350S Premium Spectrometer is a high-precision instrument. Please unpack with care.
Any vibraon or collision may cause instrument damage. If the product doesn’t work
normally or needs repair, please don’t aempt any repairs. All repairs must be
performed by the authorized customer service agent.
Most LCD screens have a very small and inconsequenal defecve pixel rate (usually less
than 0.1%). This results in occasional pinpoints of white or other colors but will not affect
the accuracy of measurements.
Do not disassemble or modify the baery.
Do not expose the baery to heat (fire) or water/moisture.
When disposing used/old baeries, wrap with insulaon tape to shield the baery from
electrical contact with metallic objects, which might ignite a fire or explosion.
If the unit is plugged into the power adapter and the baery seems to be overheang, or
if there is smoke or peculiar odors emanang from the unit, unplug immediately to avoid
the possibility of fire.
However, do not touch the cables if there is heat emanang from near the cables as
melted or deformed cables could expose wiring and result in burns or electric shock.
Do not use cloth or anything to wrap or cover the equipment while charging – this could
cause the unit to overheat, melng the casing or causing fire.
If the unit is accidently immersed in water, or if moisture has seeped inside, or metal
objects have dropped into the casing, immediately remove the baery to avoid fire or
electric shock.
Do not operate or store the baery in high-temperature environments-it will cause
baery leakage and/or shorten the life of the baery .
Do not use paint thinner, benzene or other organic solvents to clean the equipment –
this may damage the exterior finish or touch screen, and may even ignite fire.

Charge the battery full for 6 hours before using it for the first time.
To prevent power outage during using this product, please check whether the red light has
turned off (fully charged) according to instructions given in next page item1. Once this product
is enabled keep an eye on indicator of balance of battery charge at upper right corner of
screen.
In case a battery goes exhausted soon after fully charged then its life cycle has ended. Please
call your dealer for replacement with new one.
Time span your battery can last varies with its life cycle. Newly shipped battery after full charge
may last around 5 hours.

- it takes up to 3 seconds
take a measurement – the
unit beeps when it is done.
This item gives you the option
of reviewing the viewport
before you take a measurement
with the “Measure” button.
You are always prompted to
do a Dark calibration when
you turn on the unit.
However, you can perform a
dark calibration anytime
with this option.
Continuous capture function allows users to take consecutive measurements and review
results quickly without bothering with buttons - however, it does NOT allow you to save data to

TM-30 provides equaons and direcon for calculang Rf and Rg, including the spectral
reflectance funcons for the 99 CES. The IES (Illuminang Engineering Society of North
America) TM-30 color rendion method was developed by representaves of the
manufacturing, specificaon, and research segments of the lighng industry.
Dark gray area
Light gray area
Rf-Rg Plot: location analysis diagram
For comparing different light source
Rf range: 50~100
Similarity of individual standard colors with
reference to when exposed to test light source.
Rg range: 60~140
Change in saturation of individual standard
colors with the reference to when exposed to
test light source.
Color Vector Graphic：one of the outputs of TM-30.
This graph can tell us how, on average, various colors are distorted.
1. outward arrows mean more saturated colors
2. inward arrows mean duller colors
3. sideways arrows mean a hue shift
4. no arrow means that the color isn’t distorted
Rf：Fidelity Index
Rf takes a maximum value of 100. If Rf is 100, it is a match to the
reference source (true to the “real color”, similar to CRI Ra 100). If
color shifts occur, the arrows get longer and Rf decreases (to a
minimum value of zero).
Rg：Gamut Index
Rg=100 means that the test light source doesn’t change the hue or
saturation of the CES compared to the reference source.
Rg>100 indicates that the test light source increases the saturation
of the CES producing colors that are more vivid.
Rg<100 indicates that the test light source decreases the
saturation of the CES producing colors that are less saturated.

switch the table

Graphic and Rf-Rg Plot.

4.1 FLICKER
Flickers are caused by electrical currents, especially with conflicng AC current of the power
supply and DC current of the lamp design. In most cases these light source induced effects
are hard to be detected by human eyes. Yet they weaken sight and impose damage to
personal health, including visual fague and migraine headaches. Users may idenfy these
by checking the flicker measurement index of the light source.
