2. Precautions for Use

2.1 Precautions Before Operation

2.1.1 Preparing the Environment

Before taking a measurement, allow the device and the sample to rest in the same environment for at least 30 minutes to ensure that their temperatures are the same. The measurement environment must be free from direct strong light and stray light interference; avoid operating the device in environments with high temperatures, high humidity, or excessive dust.

2.1.2 Sample Preparation

The surface of the sample being tested must be flat, clean, free of stains, and free of scratches. If the sample is a powder or liquid, it must be placed in a dedicated cuvette to ensure that the sample surface completely covers the measurement aperture without any gaps; Select an appropriate measurement aperture based on the shape of the sample. Ensure that the measurement end fits snugly against the sample’s measurement area to prevent light leakage.

2.2 Precautions for Use

2.2.1 Functional Operation Specifications

Do not force a shutdown or disconnect the USB cable during the device’s self-test, calibration, or measurement processes. When switching measurement parameters, wait until the display has finished loading before proceeding to the next step. If you need to export saved measurement data, ensure the connection is established before shutting down the device to prevent data loss.

2.2.2 Contraindications for Equipment Use

Do not touch the optical components inside the measurement port with your bare hands, and do not point the measurement end toward a strong light source; do not drop, bump, or crush the device, and avoid exposing the body to water or other liquids.

2.3 Safety Warnings

Do not attempt to disassemble or replace any internal parts of the device. In the event of a malfunction, contact official customer service or an authorized dealer for assistance. Unauthorized disassembly will void the warranty;

If any liquids, dust, or other substances enter the device, immediately turn off the power, disconnect the charging cable, and contact customer service right away. Do not continue to use the device.

3. Hardware Operations

3.1 Main Unit and Accessories

After unboxing, you will find the main unit and accessories shown in Figure 3-1.

3.2 Introduction to the Host System Architecture

3.2.1 Front View

See Figure 3-2.

3.2.2 Rear View

See Figure 3-3.

3.2.3 Introduction to Accessories in the Accessories Drawer

See Figures 3–6.

3.3 Introduction to the Measurement Components

3.3.1 Reflectance Measurement Components

See Figure 3-7.

When using the device for the first time, you must calibrate it before taking measurements. The default calibration validity period is 8 hours; that is, recalibration is required after 8 hours have elapsed. Even if 8 hours have not yet passed, you must recalibrate the device as prompted if measurement conditions change—for example, if the measurement orifice is replaced. See Section 4.5.1 for calibration instructions.

3.3.2 Transmission Measurement Assembly

See Figures 3–8.

When using a cuvette, install it as shown in Figure 3-9.

When using the spring clip, you can invert the magnetic sample holder and use the spring clip to secure the sample within the measurement aperture, as shown in Figure 3-10.

If the housing cannot be closed after installing a large sample, testing can still proceed normally; however, the calibration procedure must be performed under the same conditions as the test (i.e., the housing must remain open during the calibration phase as well).

When using the device for the first time, you must calibrate it before taking measurements. The default calibration validity period is 8 hours; that is, recalibration is required after 8 hours have elapsed. Even if 8 hours have not yet passed, you must recalibrate the device as prompted or on your own initiative if you notice a change in measurement conditions. See Section 4.5.2 for calibration instructions.

4. Touchscreen Program Operation

4.1 Getting Started and Introduction to the Setup Wizard

After turning on the device, the navigation screen will appear. Follow the on-screen prompts to configure the settings as needed. See Figure 4-1.

—

The tolerance settings screen is used to determine whether a sample’s measurement results pass or fail. CIE LAB users can customize the prompt messages here. Click “Next” to proceed to the other settings screen, as shown in Figures 4–6.

Introduction to Measurement and Display Parameters:

Note: The measurement steps may vary depending on the parameter being measured. Please follow the on-screen prompts.

4.2 Introduction to the Main Menu

See Figures 4–8.

4.3 Introduction to the Measurement Interface

Take the CIELAB color difference measurement interface as an example; see Figure 4-9.

4.4 Introduction to the Settings Interface

See Figure 4-10.

4.5 Introduction to the Calibration Interface

4.5.1 Calibration Procedure for the Reflectance Measurement Assembly

Follow the instructions to perform a black calibration first, as shown in Figure 4-11.

4.5.2 Calibration Procedure for the Transmittance Measurement Assembly

See Figure 4-17.

To verify the accuracy of the transmittance measurement, set the measurement parameter to haze to display both haze and transmittance. When measuring an empty cuvette or a cuvette filled with distilled water, the transmittance should be close to 100%.

5. Using the Desktop Software

5.1 Internet Connection and Software Installation

Connect the instrument to the computer using the dedicated USB cable. Copy the software installation package to the computer (Windows 10 is recommended), as shown in Figure 5-1.

See Figure 5-4.

5.2.2.2 Report Printing Settings Interface

See Figure 5-5.

6. Daily Maintenance and Care of Equipment

6.1 Cleaning and Maintenance

6.1.1 Cleaning the Body and Display

Body Surface: Wipe dust and stains from the body with a clean, soft cloth. For stubborn stains, lightly wipe the area with a small amount of water. Do not use detergents or other corrosive liquids;

Display: Gently wipe the screen with a dedicated screen-cleaning cloth to avoid scratching it. Do not touch the display directly with your fingers. If dust gets on the screen, gently brush it away with a lint-free brush.

6.1.2 Cleaning the Calibration Plate

The calibration plate is a standard accessory; surface wear and stains will affect calibration accuracy: Gently wipe the surface of the calibration plate with a lint-free cloth; if there are stubborn stains on the surface of the calibration plate, contact customer service promptly to have it replaced. Do not sand or repair the calibration plate yourself.

6.2 Calibration Interval Requirements

To ensure the instrument’s measurement accuracy and operational reliability, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. Users may determine the specific calibration interval based on frequency of use, environmental conditions, and quality system requirements.
