Description
Samples the trigger signal before collecting the triggered measurement and sets an appropriate trigger
level automatically. When collecting data on a triggered point, a message displays on the screen while
the trigger level is being sampled.
The length of time for which the trigger is sampled during autotriggering is dependent on two factors:
• The high pass filter selected for the point.
• The lower the high pass filter cutoff, the longer the trigger will be sampled.
Mach. Speed
If the Mach. Speed is set to `Normal,' the maximum trigger sampling time is about one second. If the
Mach. Speed is set to `Slow,' the maximum trigger sampling time is about 10 seconds. The Normal
setting supports autotriggering on machines running at speeds down to ~120 rpm. The Slow setting
will support autotriggering on machines running at speeds down to ~6 rpm, depending on the width of
the trigger pulse.

Value
First (default)
Last
All
None
External (default)
Uses the trigger input from the POWER/USB/TRIGGER
connector as the trigger source.
Laser Tach
Enables the internal Laser Tachometer when a Phase or Order
measurement is collected.
Always Append: adds the new data for a point to existing
data.
Always Overwrite: replaces existing data with new data.
Always Ask (default): displays a dialog box before attempting
to store the data.
