Charger DEMO-06-C1 at Demo Site F — OMR / Sholinganallur area
5 of the last 5 contact resistance observations exceeded 0.291 mΩ — the larger of the baseline median 0.26 mΩ plus 3.5 robust spreads (spread 0.009 mΩ, from the first 12 observations) and +8% of the median. The largest deviation was 8.4 spreads (29%) above baseline.
| Readings above threshold | 5 of last 5 | needs 3 |
|---|---|---|
| Deviation threshold | 0.291 mΩ | median + 3.5 spreads, at least +8% |
| Baseline median | 0.26 mΩ | 12 readings |
| Largest deviation | 8.4 spreads | spread 0.009 mΩ |
Confidence
Based on 26 valid observations. A deviation from this charger's own history is not proof of physical degradation; measurement method changes, sensor faults or operating conditions can produce the same pattern.
Suggested action
Keep monitoring; confirm the next measurement uses the same method and conditions.
