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. -

7. PHOTOMETER 7.1. PROPER USE OF POWDER PACKET 1. Use scissors to open the powder packet. 2. Push the edges of the packet to form a spout. 3. Pour out the content of the packet. 7.2. CUVETTE PREPARATION Proper mixing is very important for reproducibility of the measurements. The proper mixing technique is listed in the method procedure. - Page 19 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.
