a. Check whether the USB cable is connected. If not, please connect it. Check whether the connection is effective. You can re-plug the USB cable to test.
b. If the USB cable is connected well but the interface still displays "USB Disconnect", please re-start the colorimeter and enter "Menu" -"Comm"to start the communication.
c. Change the USB cable or change the USB port in you PC.
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 LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.
