Minimum setup record
- Model, version, motor, impeller, battery or power source, firmware and accessories.
- Operating mode, state of charge, warm-up or stabilization time and ambient conditions.
- Fixture, outlet geometry, measurement distance, axis and instrument identity.
- Calibration status, sampling period, repeated readings and treatment of variation.
Which metric should be used?
| Metric | Use it for | Required context |
|---|---|---|
| Air speed | Velocity at a defined point or working distance | Distance, axis, sensing area, mode and instrument |
| Airflow | Total volume crossing a known area | Fixture, cross-section, velocity distribution and calculation |
| Static pressure | Ability to work against restriction | Pressure fixture, operating point, leakage control and unit |
Procedure
- Lock the approved sample and configuration record.
- Mount the unit without blocking the intake or changing the outlet.
- Mark all measurement positions before testing.
- Stabilize the selected mode, then capture repeated readings.
- Report the full set or declared averaging rule, not only a transient maximum.
- Photograph the setup and record exceptions.
Acceptance boundary
A result applies only to the tested configuration and method. A motor, impeller, battery, outlet, firmware or fixture change may require retesting.
