5–6 Blastware Operator Manual
(3) Manual Override Record Mode
Use Manual Override record mode if automatic triggering is unreliable, due to excessive wind or
nearby vehicle activity, or to record the background noise level in the vicinity of a site. The
monitor begins recording when you choose Enter Monitor Mode from the Series II Menu.
(4) Strip Chart Record Mode (Blastmate II Only)
Use the Strip Chart record mode for long–term recording periods such as monitoring pile driving
operations. Strip Chart record mode operates with Blastmate II 677 and 477 monitors.
In this mode, the monitor stores summary Event information in intervals rather than in the real
time continuous method used in the other record modes. The monitor continues to sample data
continuously at the chosen sample rate but only stores the relevant peaks for the interval. This
reduces the data recorded to specific criteria only and greatly increases the monitors recording
time. For each interval, the monitor calculates the maximum positive and negative peaks, the
frequency of the largest peak, and the peak vector sum over the entire Event. Histogram mode
prints all peaks over the entire Event along with the numerical results of the data analysis. In
tabular mode, only the numerical results print.
(5) Storage Mode (Blastmate II Only)
The Storage Mode setting determines the amount of data recorded with each Event. In the Full
Data setting, the monitor records all Event data. In Summary Only mode, the monitor records all
Event data except each channels graphical waveforms and the Compliance Report.
To select a storage mode, click on the Storage Mode drop–down menu. Click the mouse pointer
on either Full Data or Summary Only.
(6) Record Time
The Record Time setting chooses between a fixed record time and an auto record time.
To select a Record Time, click on the Record Time drop–down menu. Click the mouse pointer on
Auto for auto record time or on one of the one to ten seconds options.
(7) Record Interval (Strip-Chart Only)
Set the record interval for the Strip-Chart record mode. The record interval is the period of time
the monitor records Event information before applying the data analysis techniques. For each
interval, the monitor calculates the maximum positive and negative peaks, the frequency of the
largest peak, and the peak vector sum over the entire Event.
To choose a Record Interval, click on the Record Interval drop–down menu and choose an
interval.
(8) Trigger Source
This setting determines whether the Geophone, microphone, or both start the monitor recording if
an Events activity exceeds a preset trigger level.
To choose a Trigger Source, click on the Trigger Source drop–down menu. Choose Geophone to
start recording when an Events seismic activity exceeds a preset trigger level. Choose
Microphone to start recording when an Events air pressure exceeds a preset trigger level. Choose
Geo/Mic to start Event recording when either an Events seismic activity or air pressure exceeds
the preset trigger levels.
(9) Geophone
The following options setup the Geophone channel for recording.
Note: The Geophone must be enabled as a trigger source before these settings can be changed.
i Trigger Level
The trigger level sets a threshold that must be exceeded by an Events activity before the monitor
begins recording. Use your judgment when setting a trigger level. You must set the level high
