# Record where the cabinet pressure readings were taken

Identify the points upstream and downstream of the part being checked. Mark them on the assembly drawing and record which panel, filter and fan were installed.

When a second test uses different measurement points, keep the two setups visible in the notes. The next reviewer needs to know whether a change came from the assembly or the measurement position.

For candidate models, see [Hongbo Motor’s fan catalog](https://www.hongbomotor.com/) and request a curve with the stated test conditions.

This procurement resource was prepared for Hongbo Motor.

## Summary
Document the specific upstream and downstream measurement points on the assembly drawing alongside the installed components. Maintain clear records of these testing configurations to ensure future reviewers can distinguish between assembly changes and variations in measurement positioning.

## Themes
- Cabinet pressure testing
- Assembly documentation standards
- Fan procurement process

## Key takeaways
- Pressure readings must be taken at points upstream and downstream of the part being checked.
- Assembly drawings must be marked with the specific measurement points used.
- Records must include the specific panel, filter, and fan installed during the test.
- Multiple test setups must remain visible in the notes if measurement points change.
- Fan performance curves should be requested from the Hongbo Motor catalog based on stated test conditions.

## Insights
- Documentation must distinguish between physical assembly changes and variations in measurement methodology to ensure valid review.
- Procurement of fan components requires specific performance curves matched to defined test conditions.

## Open questions / gaps
- What specific criteria determine which panel or filter configuration is required for a test?
