SELF TRIGGER (Waveform) Mode
This mode is designed for situations where data collection is needed for a short,
precise period of time (normally less than 60 seconds). This operation captures the
complete digital waveform for analysis. With this mode, you will select pre-
determined vibration and/or sound trigger levels to activate the instrument
automatically and record the activity for the specified period of time. All activity is
stored in internal memory in a numbered event format. Once the recording is
complete, the Mini-SuperGraph II returns to a wait mode for the next event that
exceeds the trigger levels.
When you select SELF TRIGGER from the main menu and choose EDIT, you will be
able to modify the following settings:
Sample Rate – 512, 1024, 2048, 4096, 8192, 16384. Faster sample rates are
more accurate at higher frequencies, but will create larger files.
Bit accuracy – 16, 14, 12, 10 bit. Higher bit accuracy results in higher data
accuracy, but will create larger files.
Recalibrate on temp change – Adjusts A/D Midpoint after 10 degree change if
needed.
