Impact Severity is a configurable value from 1 to 100 on MiX 4000 units. It determines how much G-force must be sustained before the system logs an impact event. The setting does not apply to a single fixed timeframe. Instead, it sets a G-force threshold across three fixed impact duration windows at the same time: 50 ms, 150 ms, and 300 ms.
An impact event triggers if the recorded G-force exceeds the threshold for any one of the three duration windows, not all three.
The G-force threshold for each duration window is calculated from the configured Impact Severity value:
- 50 ms window: G-force threshold = Impact Severity value × 0.2, capped at 8 g. The cap is reached at a severity value of 40 and stays at 8 g for all higher values.
- 150 ms window: G-force threshold = Impact Severity value × 0.2 ÷ 3.
- 300 ms window: G-force threshold = Impact Severity value × 0.2 ÷ 6.
Please note that a higher Impact Severity value requires a higher sustained G-force to trigger an event, so fewer but more severe impacts are logged. A lower value logs more impacts at lower G-force levels.
