– Histogram:
Use the Histogram Record Mode for long-term recording periods such as monitoring of
pile driving operations.
In Histogram Record Mode , the unit stores summary information in intervals,
determined by the Interval Size setting, located within the Record Mode menu. The unit
continues to sample data continuously at the chosen sample rate but only stores the
relevant peaks for the selected
Interval Size . This reduces the data recorded and greatly
increases the monitor storage capacity. For each interval, the monitor calculates the
maximum peaks, the frequency of the largest peak, and the peak vector sum. For each
channel, the maximum peak and its frequency are calculated. Also the largest peak vector
sum is calculated over the entire Event.
NOTE: The Histogram Record Mode consumes more battery power than other record
modes. We recommend connecting a monitor to the supplied AC adapter or an external
12 VDC power supply.
NOTE: If you have purchased the optional Ethernet® communication cable in
conjunction with the Blastware Advanced Module , you can view Histogram data in
real-time. Refer to the that feature section for more information.
