--- The maintenance page. The configuration parameters described below are set at this page.The logical device Measurement-Converter translates of a measurement value to a physical quantity in linear context. This is for example useful to converts a measure current (in mA) to humidity, temperature or pressure.
The device calculates gradient (m = delta y / delta x) and y-intercept (n = y - m*x) from to given points configured in the device setup (minIn:maxIn and minOut:maxOut). On every change of the input measurement, a new physical quantity is calculated.
