This K-factor is the value that is entered into a batch meter or indicator/totalizer in order to give a readout in engineering units. The K value is obtained from an experimental calibration measurement in a phantom using a metabolite of known concentration. Recommended Courses Free CREO Course 24530 4.7 Enroll For Free Free The k factor is a calculation that shows how quickly a home is consuming the fuel it uses to produce heat. For the determination of the k factor, a substance composed of two elements A and B, whose composition is similar to the target substance, is used as a standard specimen. What is meant by the competitive environment? Tradues em contexto de "individually delivered" en ingls-portugus da Reverso Context : In the case of HBM optical strain sensors, the k-factor is identified on the data- and calibration sheets that are individually delivered with each sensor. . It can be transmitted to the display instrument remotely. The Flow Meter K-factor will be confirmed before it is put into use. K- and Y-factors make metal bending more precise without damaging the material. A calibration does this by matching your pH meter to the current characteristics of your pH sensor.
