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.)
