FAQs About  ISO Test Charts

a. Users must specify Standard File Name, Sample File Name and Sample Database File Name when first use.

b.Standard File is use to store standard measurement data. Sample File is used to store sample measurement data. Sample Database File is used to store the measured data exported from sample records.

Calibrating a colorimeter before testing is critical for accurate, reliable color data—counteracting instrument drift, environmental interference, and component wear to ensure measurements reflect true sample colors. It guarantees compliance with industry standards, eliminates costly rework from flawed data, maintains brand consistency across batches/locations, and ensures data comparability with clients or regulators.

Calibrating a colorimeter before use is primarily to ensure the accuracy of measurement data and compensate for errors caused by the aging of internal components (such as light sources and phototubes) or environmental changes.

Below are the specific reasons: 

  1. Compensation for Component Aging and Environmental Influences

  2. Compensation for Environmental Factors

  3. Standardization of Measurement Baselines

  4. Operational Specification Requirements

3nh colorimeters are designed for immediate measurement upon startup. However, calibration (via black-white correction) is mandatory for the first use, sudden environmental changes, or abnormal data to restore measurement accuracy.

Powder paint gloss levels are classified as:

● Flat: 0–10 GU

● Satin: 11–40 GU

● Semi-gloss: 41–70 GU

● Gloss: 71–85 GU

● High Gloss: 86+ GU
 

These are measured at a 60° angle for standardization.


There is no generic mathematical formula for gloss value. Rather, it is measured directly with a gloss meter, which compares how strongly reflected light from a sample matches a standard (typically black glass with a known reflectance).


A calorimeter is used to measure heat that is gained or lost during a chemical or physical reaction. A sample is taken in an insulated container, and a temperature change is measured. This assists in computing the alterations in energy by the equation Q = mcΔT, where Q is heat.


a. Right click "! USB Device" or "! SCI USB2Serial (COM6)", "Update Driver" -> "Install from a list or specific location (Advanced)" -> "Next" ->"Include this location in the search" -> "Browse", specify USB driver file path "CQCS3USB_Driver", click "Next". Then it will install successfully.

b.Detailed installation information please refers to "2.2 Installing USB Driver" in Color Quality Management System User Manual.doc.
