A duct traversing measurement is primarily performed when detecting airflow issues within a ventilation system. This type of measurement involves assessing the airflow characteristics at various points within the ductwork to ensure that air is distributed evenly and efficiently to all areas of a building.

By conducting a duct traversing measurement during troubleshooting or when airflow anomalies are suspected, technicians can identify specific points of resistance, blockages, or imbalances in the system. This allows for targeted adjustments to improve system performance and optimize energy usage.

While duct traversing measurements can be useful during system installation to establish baseline performance, the practice is most urgent and relevant when addressing existing problems with airflow. Additionally, although routine maintenance might involve checking airflow, it is not as focused on pinpointing system deficiencies as it is during issue detection. Seasonal changes may also prompt maintenance checks, but these are typically more about preparing the system rather than directly measuring airflow issues.
