IntroductionThe document introduces the MTCS-C2, a hardware solution for industrial color detection and measurement developed by MAZeT. It uses JENCOLOR sensors that mimic human eye perception with the RGB method, complying with DIN 5033 standards. The MTCS-C2 board integrates a
color sensor IC, signal processing, interface, and measurement control, and is adaptable for design-in projects. It includes PC software for sensor calibration and measurement output in CIE Lab color space.
Specifications
The MTCS-C2 package includes the board, documentation, optional USB cable, PC software "colorimeter2.exe" with USB drivers, and an optional macro function library. System requirements include a PC with at least a Pentium 150 MHz processor, 8 MB RAM, 5 MB free disk space, a USB 2.0 port, and Windows XP/2000.
Installation and Setup
Installation involves running setup.exe to install the software and drivers. The USB driver files "usbcolor2.inf" and "usbio.sys" are copied to specific directories. The MTCS-C2 connects to the PC via USB, and the Windows device manager should recognize it as a new device. Manual directory specification may be required if automatic installation fails.
Hardware DetailsThe MTCS-C2 board includes a True-Color Sensor MTCSiCS, a
transimpedance amplifier MTI04CQ, a microcontroller C8051F321 with a 10-bit ADC and USB interface, and EEPROM for data storage. The microcontroller manages sensor signal processing, EEPROM data storage, and USB communication.
Software Operation
The software is initiated via "mtcs.exe". It includes an ini-file "conf.ini" for setting basic functions, which should not be altered without consultation. The software supports multiple devices, serial interface selection, and Excel integration for data logging. Upon successful USB communication, the software displays the firmware revision and opens the main measurement window.
Color Detection and Measurement
The main window visualizes color measurements in various formats: XYZ color values, Yxy chromaticity diagram, CIE 1976 L*a*b* color space, and L*u*v* color space. Accurate interpretation of color values requires board calibration against a standard.
Technical Documentation Overview
The document provides detailed instructions and specifications for the MTCS-C2 system, focusing on measurement operations, data storage, system configuration, and calibration processes.
Measurement Operations
The system allows starting and stopping measurements via the "Measurement On/Off" button. The delay time between measurements can be adjusted, affecting the overall measurement time depending on other settings like averaging and system performance.
Data Storage
Data can be saved as single values or continuous logs in a .csv file. The file format includes headers with device information and measurement data separated by semicolons. Users can choose to append new data to an existing file or create a new one.
Graphical Display
The system offers graphical representation options in Yxy, L*a*b*, and L*u*v* formats. Users can clear the graph or adjust the display scale. The serial number and device selection options are available if multiple devices are connected.
Menu Functions
The menu provides options for saving values, visualizing color patches, accessing configuration files, and exiting the program. The "Color Patch" feature displays measured colors with RGB values.
Configuration Files
Configuration files (.cfg) store system settings and calibration data. The document outlines the file structure and the process for loading and saving configurations.
System Configuration
System configuration involves setting measurement parameters, environmental conditions, and calibration matrices. The process is necessary for initial setup or when changing measurement types.
Calibration
Calibration is performed using known target sets to determine system offsets and correction matrices. The process involves loading standard XYZ values and measuring RGB values on a calibrated monitor.
Important Notes
The document emphasizes the preliminary nature of the information and reserves the right for technical changes. It also highlights potential discrepancies in color representation due to different display types and settings.
Technical Specifications and Procedures
The document outlines the calibration process for the MTCS-C2 sensor. The sensor is calibrated by setting it to measure a reflective target color, and the actual value is recorded upon confirmation. If errors occur, the last measurement can be deleted and repeated. Calibration can be interrupted and returned to the 'System Configuration' interface.
Continuous Calibration
If continuous calibration is set (Wait=0 in conf.ini), it can be stopped using the ESC key. After recording all 24 actual values, data is saved, and offset values are calculated. Existing actual value files can be loaded via 'Load RGB Values'.
Matrix Calculation
Once offset-corrected actual values are available, the 'Calculate Matrix' button is activated. Clicking it computes the correction matrices, completing the calibration. The software returns to 'System Configuration', displaying the offset values and matrices.
Lighting Specification
For calculated Lab values, specify the lighting type used during calibration ('L*a*b*Light').
Data Storage
Calibration data is stored in on-board memory via 'Write to Memory', ensuring availability after each restart without recalibration.
