Evidence preparation · technical review pending
This symptom does not establish a cause or normal/abnormal limit. Collect only evidence within approved access; your site plan and qualified reviewer govern decisions.
Information to bring to review
- Identify asset, exact surface/sensor and observation time.
- Retain load/charging state, ambient conditions and measurement method.
- For infrared records, retain emissivity/reflection settings, distance and window context.
- Reference prior comparable measurements and the approved plan for review. A temperature alone does not establish a cause or acceptable condition.
