App id: MEAS-02. 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 = Von − VoffInputs
| Name | Unit |
|---|---|
| ON potential | mV |
| Instant-off potential (camera) | mV |
Outputs
| Name | Unit |
|---|---|
| Difference (ON − off) (hero result) | mV |
| Absolute difference | mV |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Signed difference is ON minus instant-off. This is not a criterion verdict.
Provenance
- CP instant-off IR-drop difference from ON and instant-off readings.
