Compare on
In the measurement interface, press the "Scan Standard" button to set current value as standard. Press the "Scan Sample" button to use current value as sample. If short press the button on the right side, another measurement will also be taken and the current value will replace the previous one. When measuring or adding a standard and measuring a sample, the color difference between the two measured values will be calculated with the following results:
 The difference value
The difference  is the sample data minus the standard data;
 Color Bias
When the measurement parameter is selected as Lab, the color bias will be judged by L, a, and b;
  E value
When the measurement parameter is selected as LabLChLuvYxyCMYK or RGB, E is calculated using the E*ab color difference formula;
 QC test
Suitable for color difference inspection in production process. If E is higher than the set threshold, it will read "NG" and sown in red; if E is less than or equal to the set threshold, it will read "Pass" and display in green.

c) If the product model does not match, it will prompt "Unmatched device model ". Please connect to the correct model before importing.

VI PC Software
You can use the PC software to connect the computer via USB. The software has functions of color compare measurement, reading compare record, export compare data to Excel, spectral reflectance measurement, qualified number, unqualified number, total number statistics, report generation and printing, etc. For specific operation, please refer to the "Color Haze Meter Software Operation Manual".

VII Precaution
1. When the colorimeter has not been used for a long time, it is recommended to perform calibration before using.
2. Please ensure that the sample is evenly colored with a flat and clean surface, otherwise it will affect the measurement accuracy.
3. The calibration cover should be adsorbed to the iron shell after it is removed from the main unit to avoid fouling of the standard plate.
4. Do not apply any objects to the glass of the measuring port, as this will damage the instrument and affect the measurement accuracy and operational safety.
5. When the instrument is not in use, put on the calibration cover to prevent dust from entering or prolonged humidity, which may affect the measurement accuracy.
6. It's recommended to calibrate the instrument once each year. And we offer calibration service. 7. Due to color difference in the LCD display, the color displayed on the instrument screen is for
