How Does PCS Handle the 100mV Shift Criteria?

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 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
