Test color difference steps
Place the instrument steadily on a flat object for testing.
Step 1: Black calibration test
Step 2: White calibration test
Step 3: Test the standard sample
Step 4: Testing and Testing
After the test is completed, the chromaticity and color difference values are obtained,
Chromaticity values: L * a * b *, L * c * h *, Δ E * ab, XYZ, relative RGB values;
Color difference values: Δ (L * a * b *), Δ (L * c * h *)
