Standard programs
5.5.1 Take a color measurement
1. Press Color Measurement.
2. Insert a cuvette/sample cell with distilled water to calibrate.
Note: Always carry out the calibration very carefully, as a faulty
calibration can cause inaccurate results to be obtained.
3. The calibration starts automatically once the instrument has
detected the cuvette.
The type of cuvette/sample cell used and the exact progress
of calibration is shown in a separate window.
4. After calibration, the cuvette size used is displayed in the top
right.
Note: After calibration, you can measure the cuvette with distilled
water again as a sample.
The displayed measured values should match the uncolored color
indices (i.e. Hazen = 0, Gardner = 0.0, CIE L*a*b* = 100.0, 0.0, 0.0,
etc.)
5. Insert the test cuvette.
The measurement starts automatically.
The result of the color calculation is displayed.
Note: The bar on the right next to the result shows the result relative
to the measurement range.
6. For the next measurement, remove the cuvette and insert the
next sample cuvette, or press Measure to measure the same
sample again.
