Subjective real scene test chart is based on personal subjective feelings, building a test scene, taking photos with a camera, and then subjectively judging the performance of the camera in all aspects through the photos.

The YE0688 real scene test chart has different wood patterns, sponges, brushes, feathers, black velvet, and dead leaves. The image card can be used to analyze the texture expression of the lens on different materials. There are various colored pens, pigment tubes, 24 color cards, portraits, etc. that can be used to analyze the color reproduction of the lens. The text on paper currency, the text on the label on the paint tube, and the resolution card can be used to analyze the resolution situation.

FAQs About  Other Charts

Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.


The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

A coating thickness gauge measures film layers by identifying shifts in magnetic flux, eddy currents, or ultrasonic echoes as they penetrate the coating. The gauge calculates thickness based on the magnitude of these signals. This universally accepted approach results in quick, reliable, and non-invasive measurements. 

A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.


A powder coated surface is most commonly measured for thickness post curing using a digital coating thickness gauge. This method is non-destructive, helps verify coverage uniformity and meets quality control standards. A powder comb gauge is used to estimate thickness for a pre-cured coating.

a. When the colorimeter is disconnected to the PC, "Connection Timeout" will occur. At the moment, you have to check whether the USB cable is well connected the colorimeter and the PC. Then you can re-plug the USB to try out.

b. After ensuring the colorimeter is connected to the PC with USB cable, turn on the colorimeter and enter the main menu. Select "Comm" and press "Enter" key to start communication.

c. Turn off CQCS3 software, and reopen it.
