Thus, an MCD measurement project always contains ameasurement recipe and an analysis matrix which contains the gas specific calibrationfactors. The MCD measurement project is closely related to a gas specific calibrationwhich is needed to determine the relevant calibration factors. Note that you shouldperform the gas specific calibration directly before the MCD measurement project.Analysis matrix (MCD Matrix Editor)The analysis matrix connects the MID measurement recipe with the gas components:•The rows of the analysis matrix are defined by the name of the gascomponents for the quantitative analysis.•Use the "Add MCD Task" tool to add a row (gas component) to the matrix.NOTE:In the MCD project, use identical names for the gas components as used inthe gas specific calibration.
Otherwise, QUADERA® cannot refer to thecomponents. As an example, QUADERA® does not equate "O2" and"Oxygen".•The columns of the analysis matrix are defined by the measurement recipe,and correspond to the mass numbers in the measurement tasks.•The individual matrix elements represent the gas specific calibration factors forthe quantitative gas analysis. The calibration factors are determined in the gasspecific calibration and stored in the MCD Calibration Factor Library.161QUADERA HTML HelpRecipe Parameters: Total PressureThis chapter is valid for the QMG220 only.NOTE:New or modified parameters for the measurement tasks are accepted by thedevice only after the measurement has been restarted.The following recipe parameters are available::Task NameDwellDetector TypeTrip TypeLevel ADO# ALevel BDO# BStateParameterRangeDescription•Task NameLetters anddigitsName of the measurement task.•DwellDropdown listDwell time for the measurement ofthe total pressure.•DetectorType(not editable)Detector type "TotalPressure":installed total pressure gauge162QUADERAParameterRangeDescription•Dropdown listThe trip function can monitormeasurement values of total pressuremeasurements.
