An empty unit shows air response; a loaded unit includes product and packaging effects, so the tests answer different questions.
Locate the issue
An empty test can screen the body and cooling-source arrangement. Verify product performance with planned load and placement.
Build the comparison. State the test purpose; keep sensor points consistent and record empty, representative and planned loads separately.
Four control fields
- Test purpose
- Load state
- Sensor point
- Decision scope
An empty-unit result does not guarantee a loaded shipment. Interpret each curve only for its stated decision.
