Electrical pulse signals are induced at both ends of the coil. Default values apply to standard PLA with a 0.4mm nozzle. A calibration curve is an empirical equation that relates the response of a specific instrument to the concentration of a specific analyte in a specific sample matrix (the chemical background of the sample). Once the meter factor is determined it is used as a volume correction in the calculation for net standard volume of a receipt or delivery of liquids. Multiply this value by 100% to obtain the percent error. The k-factor values for Linear Advance 1.5 are vastly different from Linear Advance 1.0, and those k-factor values should fall somewhere between 0.0 and 2.0.

We deliver a known amount of energy and measure the resultant rise in temperature. In analytical chemistry, calibration is defined as the process of assessment and refinement of the accuracy and precision of a method, and particularly the associated measuring equipment (i.e., an instrument), employed for the quantitative determination of a sought-after analyte [2]. This is done by taking the information on the flow meter manufacturers calibration sheet and calculating the K-factors. In practice, calibration also includes repair of the device if it is out of calibration.
