Single-point calibration is insufficient for complex leak testing. If any aspect of the process change from test to test. Theory-Based Signal Calibration with Single-Point T1 Measurements for First-Pass Quantitative Perfusion MRI Studies Some people at work are suggesting the use of single point calibration in-place to calibrate our thermocouples/RTDs, and prevent damaging them through removal. Purpose Artifact calibration is a measurement process that assigns values to the property of an artifact relative to a reference standard(s).
