Trigger on XY Vector or Z axis
An event is triggered when either:
• The magnitude of the Z acceleration exceeds the Z Axis Event Trigger Level, or
• The magnitude of the XY acceleration vector exceeds the XY Vector Event Trigger Level.
An event is considered as a severe event when either:
• The magnitude of the Z acceleration exceeds the Z Axis Severe Event Trigger Level, or
• The magnitude of the XY acceleration vector exceeds the XY Vector Severe Event Trigger Level.
The trigger filter setting used for the Z axis is separately configurable to the setting used for the X and Y axes.
Trigger on X or Y or Z axis
An event is triggered when either:
• The magnitude of the Z acceleration exceeds the Z Axis Event Trigger Level, or
• The magnitude of the X or Y acceleration exceeds the X and Y Axes Event Trigger Level.
An event is considered as a severe event when either:
• The magnitude of the Z acceleration exceeds the Z Axis Severe Event Trigger Level, or
• The magnitude of the X or Y acceleration exceeds the X and Y Axes Severe Event Trigger Level.
The trigger filter setting used for the Z axis is separately configurable to the setting used for the X and Y axes.
General Notes on Triggering:
• The event trigger starts the event logging process. The log contains 2 seconds of pre-trigger data and 30 seconds
of post-trigger data.
• The log files generated by ADR Manager contain the trigger filter output that was used to trigger the event. These
readings can be used to determine suitable filtering and thresholds.
