Identify the isolation criteria for casing inspections. Type a value in the field Casing Criteria Minimum Difference Between P/S and C/S to set the minimum difference allowed between pipe-to-soil (P/S) and casing pipe-to-soil (C/S) readings before the casing is considered shorted. The default setting is 100 mV.
|
Note: PCS Axis displays a warning message when the minimum difference does not meet the casing criteria for an inspection reading entered in the data entry grid. Similarly, an entry is added in the Field Computer Log when inspection readings transferred from the Allegro do not meet casing criteria.

Identify the number of days after an inspection reading is taken, that a native pipe-to-soil (P/S) reading is taken. Type the number of days in the field Days To Look Forward From Inspection For Native P/S.
|
Note: The number of days effects the system calculation for the fields Effective Native P/S and Effective Native Date in data entry grids. Native P/S is a potential reading taken prior to any current placed on the pipeline. It is also referred to as a depolarized or static potential reading.
