Change between a previous and current pipe-to-soil reading.
Cathodic Protection
Change between a previous and current pipe-to-soil reading.
App id: MEAS-05. Reference version 1.0.
How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
ΔV = Vnow − VpreviousInputs
| Name | Unit |
|---|---|
| Previous potential | mV |
| Current potential (camera) | mV |
Outputs
| Name | Unit |
|---|---|
| Change (hero result) | mV |
| Cathodic shift (previous − current) | mV |
| Change vs previous magnitude | % |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- A movement in the negative direction is the usual cathodic direction and is reported as cathodic shift.
Provenance
- Historical comparison of two pipe-to-soil readings. Not a trend engine.
