F3 - Snapshot






A stream of data can be stored by the Tech-1 in snapshot mode (F3) to help isolate an intermittent or transient problem. The Tech-1 continuously refreshes the data by pushing out the oldest (earliest) data to make room for the new (latest) data. A "trigger" point is used to tell the Tech-1 when to start or stop recording data. The trigger point will determine what data will be captured by the Tech-1.
