Setting Trigger Levels
The trigger icon allows you to configure the diagnostic tool to automatically save PID data from
buffer memory to a file when a parameter value crosses a threshold. When triggering is armed, a
"Trigger event" pauses data collection and saves data to a file.
Selecting the
Trigger
icon opens a menu that includes:
•
Set Trigger
—establishes upper and lower signal values to initiate an event capture for the
highlighted parameter.
•
Arm Trigger
—activates the diagnostic tool to capture an event when the signal crosses a
threshold value.
