1.3 Annual Product Calibration

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.

1.4

Product Notes and Precautions

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.

red line：test source

gray line：reference 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

Warranty Principles

UPRTEK provides the service of repairing or changing equivalent products for the customer in case of the material or functional defect and fault during the product warranty period.

1.Changing new product:

■

If the consumer finds any functional defect or fault or finds any part missing within 7 days after purchasing the product, it should consult the original seller and report to the vendor immediately. Moreover, it should leave the contact information, so the customer service personnel of the original vendor will check it out and generate the number of changing new product for the customer. In this case, the original vendor provides the service of “changing new product” within 7 days.

■

The customer should return the product to the original vendor within 30 days after getting the repair number. As for the international customer, it permits the flexibility of logistical time and expands the time for returning the product to the original vendor.

Remarks: It requires complete package when returning the product to the original vendor. There should be no part missing or scratch on the surface unless the part is found missing when the product is delivered. Under this circumstance, the original vendor reserves the ultimate right to determine whether to change new product.

2. Repair service:

■

If it exceeds the period for changing new product (seven days), the functional non-compliance or defect found on the product should go through RMA workflow. When any product needs to be returned to the original vendor for repair, it should consult the business service personnel via Email, fax or phone call to apply for repair number before returning the product to the original vendor for repair service.

After the original vendor receives the returned product, the internal engineer of the Company will check it initially and confirms the causes for product defect. If it is within the warranty period and it is the functional fault of the product, it should follow the general repair workflow. However, if the engineer checks it is human damage rather than functional fault, it is inapplicable to the warranty term.

Remarks: To avoid damage during the product transportation, we strongly recommend choosing international express service and protecting the product carefully.

Limited Warranty

The warranty term is inapplicable to the damage caused by unnatural or external factors, such as the following circumstances:

1.When the fault is caused by the natural disaster and improper human operation rather than the product itself;

2.When the product is repaired or disassembled by others rather than the technician authorized by the company;

3.When the warranty volume label or disassembly-proof volume label is modified, damaged or gone;

4.When the product serial number is wrong, damaged or unclear.

Exemption from Liabilities

■

The sensitivity of human eyes

varies with the light of

different wavelength. It can

get the data such as

illuminance based on the

brightness function. However,

the brightness function is

different for human eyes

under high brightness and

low brightness. Therefore, it

---

defines the ratio of photopic

vision under high brightness

and scotopic vision under low

brightness, which is called S/P

ratio.

The Gamut Area Index is the

ratio between the area of the

eight standard colors (R1~R8)

on CIE1976 coordinate

measured by CRI and the

area measured with the

---

standard illuminant E(x,y =

0.333, 0.333). The higher the

value is, the more saturated

and bright the color is.

The transmittance is defined

as (the radiant flux

transmitted/the radiant flux

received)x100 %, based on

which the wavelength

response can be obtained.

It is a rating method proposed

by IES for the performance of

light source. Different from 8

standard colors, it defines 99

standard colors to present the

performance of various

wavelengths. Rf represents the

similarity between the target

light source and the reference

light source under the standard

colors. The value 100 represents

it is identical, while the value 0

represents great difference. Rg

represents the saturation

---

difference between the target

light source and the reference

light source under the standard

colors. The value 100 represents

the saturation is the same, while

the value larger than 100

represents saturation is higher,

and the value smaller than 100

represents saturation is lower.

Moreover, it could identify the

difference more obviously

Power-on failure

(No display)

Check whether the

battery is installed

correctly.

Check whether the

battery runs out of power.

Check whether the

battery connector is dirty.

Please don’t install the battery

inversely, or push it in violently,

which may destroy the battery

spring.

Please charge the battery for 6

hours for the first use. (Please refer

to 2.1)

Please wipe it with dry cloth.

Item

Why I feel the card is stuck when inserting and unplugging it?

What is the function of dark calibration?

Do I need to perform dark calibration at every startup.

Why my SD card can’t be used on

MK350N Premium?

- 59 - - 60 -

Solution

It is the anti-shedding function designed specially. It prevents SD card shedding in case of collision under external force, which may cause write-in error.

The dark calibration is also known as zero calibration. As the temperature change of the environment affects the measurement results, the user is suggested performing dark calibration before measurement, so as to improve the measurement accuracy. (As for the calibration instruction, please refer to 2.6).

The SD card should be formatted into FAT before being inserted into MK350N Premium. Moreover, the memory of SD card is required to be 1G or higher.
