As the product is a high-precision instrument, please use it cautiously.
To ensure the accuracy of measurements, annual calibration is recommended.
Please consult the agent or the customer service department for the
calibration service.
MK350N Premium Spectrometer is a high-precision instrument. Please
unpack with care. Any vibration or collision may cause instrument damage.
If the product doesn’t work normally or needs repair, please don’t
attempt any repairs. All repairs must be performed by the authorized
customer service agent.
Most LCD screens have a very small and inconsequential defective 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.

Precautions / Warnings
Please read the following precautions to avoid fire, excessive heat, chemical
leakage and explosion :
◆ Do not disassemble or modify the battery.
◆ Do not expose the battery to heat (fire) or water/moisture.
◆When disposing used/old batteries, wrap with insulation tape to shield the battery from
electrical contact with metallic objects, which might ignite a fire or explosion.
◆If the unit is plugged into the power adapter and the battery seems to be overheating, or if
there is smoke or peculiar odors emanating from the unit, unplug immediately to avoid the
possibility of fire.
◆However, do not touch the cables if there is heat emanating 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, melting 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 battery to avoid fire or electric shock.
◆Do not operate or store the battery in high-temperature environments-it will cause battery
leakage and/or shorten the life of the battery .
◆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.

TM-30 Mode Introduction
TM-30-15 provides equations and direction for calculating
Fidelity Index (Rf) and gamut (increase or decrease in chroma)
through a Gamut Index (Rg), including the spectral reflectance
functions for 99 Color Evaluation Samples (CES).
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.
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
