How To Use:

Instrument operation

1. Power on/off

Power on: Short press the button on the back of the instrument to power on

Shutdown: Long press the button of the instrument to shut down or click on the menu bar "Shutdown" to shut down, if automatic shutdown is set, the instrument will automatically shut down when the time of inactivity is longer than the set automatic shutdown time

2. Equipment calibration

After entering the "equipment calibration" interface. The user can perform the calibration operation according to the calibration animation prompt, or skip the calibration. When the instrument has not been used for a long time, it is recommended to calibrate. You can also set the language in the calibration interface. If it is currently displayed in Chinese, click "English" to switch to English, if it is currently displayed in English, click "Chinese" to switch to Chinese

If it prompts that the calibration failed, the possible reasons are as follows:

The bottom cover is not closed

The standard plate on the bottom cover is too dirty and needs to be cleaned

Light source attenuation causes malfunction

3. Measurement

Enter the main measurement interface. There are two measurement modes: "color difference contrast" and "color measurement". You can click the button at the bottom of the screen to switch, and the font of the button will turn blue after selection

Chromatic aberration contrast

In the color difference contrast measurement interface, click the "standard color measurement" button, and the current measured value will be used as the standard color. Click the "Sample Color Measurement" button, and the current measured value is used as the sample color. If you short press the instrument button, a color measurement will also be performed, and this measurement value will replace the last measurement data. When the standard color is measured or added, and the sample color is measured, the color difference calculation will be performed on the two colors. The color difference comparison results generally have the following three judgments:

LabCh difference

The LabCh difference A is the sample color data minus the standard color data, and the direction of color cast between the two is judged by AL, La, and Ab

△E value

The value of △E is calculated according to the selected color difference formulas

QC testing

QC detection is suitable for color difference detection in the production process. If the calculated △E is greater than the set threshold, it will display "unqualified", and the judgment area will display red, if the calculated AE is less than or equal to the set threshold, it will display "qualified" , the judgment area is displayed in green

Product introduction

LS172 is a handheld multifunctional colorimeter designed with a 45°/0° optical geometric structure. It uses a 3.5-inch IPS color screen and a capacitive touch screen to provide an excellent operating experience. The color analyzer integrates multiple color charts, which can quickly match the three closest color codes. At the same time, it has a color difference comparison function, support multiple standard color addition methods, color difference thresholds can be set, color difference formulas can be flexibly selected. QC testing can be achieved.
Colorimeter Application

LS172 color analyzer is designed with a 45°/0° optical geometric structure and has a wide range of applications. It is usually used in product color measurement and management, product color difference quality control in paint, paper printing, decorations, leather and cotton, textile printing, plastics and other industries.
1. Touch screen control, perfect viewing angle

The instrument uses a 3.5-inch IPS color capacitive touch screen, no button settings are required; the screen is tilted at 20 degrees and has a perfect viewing angle, which has a good user experience and human-computer interaction interface.
2. Portable color analyzer, easy to carry

Small and portable, easy to store and carry; stable body, ergonomic design, more stable measurement data.
3. Refusing to be burdensome and simple to choose

Built-in multiple electronic color charts, quickly matching the closest 3 color codes, the accuracy rate is as high as 90%.
4. Color measurement and color difference comparison

Reject complex operations and make the measurement simpler. The color difference meter can be used in 5 seconds to get started. Color measurement can be achieved by touching the screen button or pressing the power button. The color values can be quickly measured in 1 second.

Two clicks can complete the color difference comparison, turn on the QC testing function, batch testing can be performed. The color difference threshold can be set to quickly achieve color quality control. And provide the color deviation indicator of Lab values, making color adjustment easier and more convenient.
5. Seven color spaces and six color difference formulas

The color meter has a variety of color spaces such as LabRGBCMYK and a variety of color difference formulas to choose from, matching the color measurement needs of various industries.
6. Large storage space

The instrument has built-in large storage space, which can store 1000 colors and 1000 color difference comparison records respectively.
7. Compensation optical path technology

The color difference meter has a built-in compensation optical path with stable values and allows long-period calibration.
8. Whiteboard calibration, simple operation

The bottom cap integrates a calibration whiteboard, so there is no need to worry about losing it. No need for tedious operations.
9. Locating plate makes color measurement more accurate

The color difference meter is equipped with a measurement locating plate to meet the needs of precise alignment and make the measurement more accurate.
10. Energy saving, low power consumption

Built-in lithium battery, can be used 10,000 times continuously under full charge. The default auto off time can be set.
