Comparing a shaded trip with one parked in sun can mislead the review.

Record exposure

Use actual container exposure intervals, not only the daily maximum.

Matching fields

  • Internal and ambient sensor IDs
  • Time interval
  • Parking and shade state
  • Load condition

Read curves over the same interval

Align internal and ambient readings, then group trips by similar exposure.

Investigate differences

If similar exposures yield different curves, review loading, doors and equipment records.

Ambient readings are not product measurements. Assess product status using relevant readings and authorized review.
