Counting items and checking damage at delivery does not show whether equipment meets needs in the workflow. Build the acceptance plan around the purchase specification and intended site.
Before the test
Agree in writing on the task and acceptance criteria.
Match model, accessories and plate or power configuration to the order.
Select loggers with known calibration status and define measurement points.
Assign safe loading, access and operator responsibilities.
Set up the test sequence
Use an empty unit for inspection or preparation; do not infer performance from an empty load.
Choose a load representative of the product, packaging and arrangement in real work.
Record start, handoff, ambient conditions and lid events against one clock.
Show each logger position on a diagram.

| Deviation | Acceptance criterion and owner |
If measurement points differ, do not hide the difference with an average. Review each sensor location and trace separately.
Approve the result
Keep the report with date, conditions, load details, device IDs and raw-data link.
A manufacturer's calculation or test does not replace your site trial; keep their scopes distinct.
List changes that require review: revisit the plan when product, route, layout or configuration changes.
Tie pass or fail to the specification and recorded deviations.
Before signing, name missing records and the owner of each correction. This lets later deliveries use the same criteria.
