Both types of transducer are calibrated by subjecting them and an accurate reference transducer to a continuous sweep of input parameter. Graphs are drawn by an X-Y recorder of either the direct output of the transducer under test or its output suitably processed to show departures from the ideal nominal linear output. 收起
