What does Summary Data Only mean?

You have downloaded records and one or more of the records in the File Review List has the notation "Summary Data Only" in the Notes column.  This means there is a no waveform or bargraph data stored with the record.  The three most common ways this can happen are as follows:

Because the Mini-Seis automatically activates when a sensor is connected, it also means that the unit will shut down when all sensors are removed.  However, the act of removing the sensors will cause a trigger.  Therefore the instrument may shut down in the middle of a trigger which means the data cannot be stored.  The solution is to either use the Trigger Disarm button or the Reset button before disconnecting the sensors. Depending on the duration, the instrument can store a limited amount of data from continuous triggers.  Multiple back-to-back triggers can cause one or more records to be "Summary Data Only." If WRAP is turned ON, when the memory is full the next event will replace the waveform data for the oldest event.  If you do not download in time it is possible some older events could be "Summary Data Only." If WRAP is OFF, when the memory is full the instrument will no longer store waveform data for any subsequent events until the memory is cleared.
