And how to calculate? In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration. The calibration highlighted in Red is a passed calibration curve for an assay that conforms to the standard values provided by the manufacturer. Here are the steps we recommend taking to calculate the K-factor for Linear Advance: Follow this link to Marlin firmware's K-factor calibration calculator, which produces a calibration pattern you will be printing. Its foundational to a consistent experience for customers. Calibration Range The zero value is the lower end of the range or LRV and the upper range value is the URV. K factor uses the formula K factor = /T. The correction factor in a measured value retains its importance in properly evaluating and investigating the veracity of an experimental result.
