Page 9: Precision & Accuracy
5.3. PRECISION & ACCURACY Precision is how closely repeated measurements are to one another. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the closeness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions. -

Page 19: Cuvette Preparation
7.2. CUVETTE PREPARATION Proper mixing is very important for reproducibility of the measurements. The proper mixing technique is listed in the method procedure. (a) Invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position. - Page 20 Whenever the cuvette is placed into the measurement holder, it must be dry outside and free of fingerprints, oil or dirt. Wipe it thoroughly with HI731318 microfiber cleaning cloth or a lint-free wipe prior to insertion. Shaking the cuvette can generate bubbles in the sample, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.
