2. Open device alert tab and click on the Off spec alert sub tab.

 How Off spec alert works

1. Duration-Based Sample Collection:

-  It retrieves all data intervals (samples) within the configured time duration.

2. Sample Evaluation:

- Each sample is analyzed to see if it falls outside the target percent range.

- If the black line (actual) has most of its points outside the configured target range, then the corresponding Data Interval (Sample) is marked as Off Spec.

3. Alert Trigger Logic:

- The system calculates the percentage of samples that are Off Spec.

- If this value exceeds the configured alert, it triggers an Off Spec Alert Email.

 Example

• Configured Off Spec Alert : 50%

• Total Data Intervals (Samples): 10

• Off Spec Intervals: 6

• Calculated Off Spec Percentage: 60%

✅ Since 60% > 50%, an Off Spec Alert Email will be sent to the configured address.
