ERI — Earthquake Recording Instrument

⚙️ Threshold Configuration

✓ Applied

Trigger Threshold (m/s²)

TF resultant above this starts recording an event. Normal ≈ 0.6 m/s².

Normal Range (m/s²)

Fallback baseline used until auto-calibration collects enough samples (expected: 0.6–0.7 m/s²). Auto-calibration updates this live from idle readings.

Structure Name

Identifies the monitored structure in event logs and exports

Buffer Duration (seconds)

Record data ±N seconds before and after the event window

Displacement Limit — d_lim (mm)

NSCP-based allowable storey displacement. Used for BT/SAT/GAT classification

OVERALL STRUCTURE STATUS
