Part 7 of our FanTestic series covers how to adjust the settings to prepare for an auto-test.
Part 7 in Retrotec’s FanTestic software series dives into the crucial setup of Auto-Test settings, ensuring your automated blower-door test runs smoothly and produces reliable results ([turn0search0], [turn0search5]).
Key Configuration Steps
Select Target Pressures
Choose specific pressure setpoints (e.g., 50 Pa, 25 Pa) you want the software to cycle through during the auto-test.Set Stabilization Criteria
Define how long the software should wait at each pressure—based on stabilization time or variance tolerance—before recording data. This ensures accurate, consistent readings.Configure Ramp Rates
Adjust how quickly the fan ramps up or down between pressure steps. A gentle ramp avoids overshoot and helps prevent test instability.Define Averaging & Logging Intervals
Determine how often the software should sample and record data (e.g., every 5 seconds) and whether to use averaged or instantaneous values for results.Enable Auto-Transitions
Adjust settings for automatic movement between pressure points once stabilization criteria are met, ensuring the test flows uninterrupted.Apply Fail-Safe Limits
Set maximum fan speeds or pressure thresholds to pause the test automatically if readings exceed safe or expected ranges.
Why Adjusting these Settings Matters
Test Accuracy: Proper settings ensure each data point represents a stable, valid measurement.
Efficiency: Automated transitions reduce manual oversight—tests finish faster and with less operator input.
Repeatability: Applying consistent settings enables apples-to-apples comparisons between multiple test runs.
