The <font color="#0000FF">'''PRI index''' </font>'''Tab''' shows the '''''Pressure Residual Intensity Index''''' for the measurement chain in use (both numerically and graphically) and the comparison with the IEC 61043 Standard Limits. Using the Load and Save buttons, the user can retrieve from or write to the disk several PRI profiles. Pushing the Set IEC 61043 PRI limits button, the default limits specified in the standard are loaded. The PRI here used is referred to the actual measurement chain and it follows the advices of the standards: the PRI is the one for the 25mm spacer. During the measurement the software automatically computes, depending on the spacer in use and its frequency range, the corrected values for each active frequency band. The values of the PRI spectrum can be edited typing in the Lp and Li cells (useful if the user has the probe/system calibration chart from the producer or the Calibration Laboratory). | The <font color="#0000FF">'''PRI index''' </font>'''Tab''' shows the '''''Pressure Residual Intensity Index''''' for the measurement chain in use (both numerically and graphically) and the comparison with the IEC 61043 Standard Limits.
