(AI KB) How Does PCS Handle the 100mV Shift Criteria

This is meant to show how PCS determines if a Test Point meets the 100mV shift criteria.

Please Note: you need a Native P/S reading within the range your PCS Admin has set for this calculation to work.

• If the Structure IRF has been recorded, it will calculate it against the Effective Native and only use the 100mV shift criteria.
• The Target Structure P/S is used to determine if the reading passes criteria only when there is not a Structure IRF included with the current reading.
• The Effective IR Correction and Target Structure P/S are carried forward until a new On/Off pair are collected. Then it will be recalculated and carried forward.

PCS Inspection Records Data Grid Screenshot above with examples.

PCS System Field Calculation:

Target Structure P/S = Native P/S – 0.100 – | Structure P/S – Structure IRF |

Example

-.406 – 0.100 - | -1.000 – -0.700 |

= -0.506 – 0.300

= -0.806
