4. Setup
4.1 Instrument Structure Overview
- Type-C Port: For charging the device.
- Scan QR Code: To download the companion mobile application.
- Display Screen: 3.5-inch IPS touch screen for operation and viewing results.
- Power Button: To turn the device on/off.

4.2 Initial Calibration
After a long period of non-usage, it is recommended to perform a calibration. Enter the "calibration" interface on the device. Follow the on-screen animation for the calibration process, or skip it if recently calibrated. Ensure the standard tile on the bottom cap is clean and the cap is closed properly for accurate calibration.
5. Operating Instructions
5.1 Basic Measurement
The default measurement parameter is "Lab". To change parameters, click the "Param" button at the top of the screen. You can select various parameters such as Lab, LCh, Luv, Yxy, CMYK, RGB, YI-98, WI-98, WI-Gauz, WI-Hunter, WI-R457, HSL, HSV, ITA, and Spectra.
5.2 Color Matching and QC Function
The LS173 can quickly match measured colors to the three closest color codes from its built-in digital color charts. It also features a QC function for pass/fail judgment based on a customizable color difference threshold (ΔE*ab).
The total color difference (ΔE*ab) indicates the deviation from a standard. Refer to the table below for interpretation:
5.3 Advanced Features
- Create and Save Palettes: Store large amounts of color data to prevent fading of physical samples over time. You can organize projects and share saved colors.
- Spectral Reflectance Curves: The device provides spectral reflectance curves, which are useful for analyzing the hue, saturation, and shade of a sample color.
- Whiteness and Yellowness Measurement: Supports specific color formats for measuring whiteness and yellowness indices.
- ITA Skin Color Parameter: The ITA value is an important parameter for assessing skin tone, making the device suitable for certain cosmetic applications.
5.4 Mobile APP and PC Software
The LS173 features a Bluetooth communication module, allowing connection to a mobile phone APP. Scan the QR code on the instrument body to download and install the "LScolor" APP. Open the APP, search for the device, and establish a connection as prompted.
For advanced functionality, connect the colorimeter to a computer via USB. The dedicated PC software offers comparison measurement, record reading, data export to Excel, statistics of qualified/unqualified numbers, and report generation/printing.

6. Maintenance
- If the colorimeter has not been used for a long time, it is recommended to perform calibration before using.
- Ensure the sample is evenly colored with a flat and clean surface. Irregular or contaminated surfaces will affect measurement accuracy.
- After removing the base from the host, store it in a clean place to avoid contamination of the standard tile.
- Do not insert any object inside the colorimeter to clean it, as this will cause damage and affect measurement accuracy and operational safety.
- Charge the colorimeter in time when the battery is low.
- If not in use for over 6 months, charge it regularly to prevent battery over-discharge and damage.
- It is recommended to calibrate the instrument once each year. Calibration services are available from the manufacturer.
- Due to the color difference of the LCD screen, the color displayed on the instrument screen is for reference only.
7. Troubleshooting
If calibration fails, consider the following possible reasons:
- The bottom cap is not closed properly.
- The standard tile on the bottom cap needs cleaning.
- The light source has attenuated, requiring the device to be returned to the factory for inspection and repair.
8. User Tips
- The LS173 colorimeter supports Bluetooth connectivity for mobile app integration and also connects to PC software via USB for comprehensive data management.
- The device can store a significant amount of data: 1000 records for color comparison, 1000 records for color scanning, 1000 saved standards, and 100 spectral curves. It can manage up to 46 color charts with a total of up to 20,000 color codes.
- While primarily designed for paint, coatings, metals, and plastics, the LS173's ability to measure whiteness, yellowness, and ITA (skin color parameter) suggests potential utility for certain cosmetic products, especially those that are white or off-white, though direct suitability for liquids/creams is not explicitly stated.
9. Warranty and Support
- The colorimeter comes with a one-year warranty. If the device malfunctions, please send the entire instrument to the manufacturer for maintenance.
