sum is calculated over the entire Event is also displayed. Select the drop-down list to set the
desired Histogram Interval time.
(6) Enable Standard Geophone
The Geophone channels record ground vibrations. In this section of the dialog box, you enable the
geophone channels by selecting the Enable Standard Geophone option.
i Enable Trigger
Click on the Enable Trigger checkbox to use the geophone channels as a Trigger Source. For
example, when selecting the geophone as a trigger source, Event recording begins on all these
channels when Event activity exceeds the Trigger Level of the geophone. Refer to Trigger Level,
below.
ii 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
enough so the unit does not trigger on unwanted Events such as nearby vehicle traffic. At the same
time, you have to set the trigger level low enough so that an Events activity exceeds the trigger
level and starts the unit recording.
To set a trigger level, click on the Trigger Level box. Enter the new level.
Note: In certain situations, the actual trigger level may be lower than the trigger level that you
entered. This is because the monitor converts the analog signal it receives from the
geophone into digital data, which consists of a series of discrete values. If the trigger level
that you entered does not match one of these values, Blastware automatically sets the
trigger level to the nearest lower value.
The available Trigger Level range is 0.127 – 254.0 mm/s.
(7) Enable ISEE Microphone
The microphone channel records air over pressure. In this section of the Micromate Recording
Setup dialog, you enable the Microphone ISEE Channel, select the channel as a Trigger Source,
and set a Trigger Level.
i Enable Trigger
Click on the Enable Trigger checkbox to use the microphone channel as a Trigger Source. For
example, when selecting the microphone as a Trigger Source, Event recording begins on all these
channels when Event activity exceeds the Trigger Level of the geophone. Refer to Trigger Level,
below.
ii Trigger Level
Set a Trigger Level for the microphone. To set a Trigger Level, click on the Trigger Level text
box. Enter the new level.
Note: In certain situations, the actual trigger level may be lower than the trigger level that
you entered. This is because the monitor converts the analog signal it receives from the
microphone into digital data, which consists of a series of discrete values. If the trigger
level that you entered does not match one of these values, Blastware automatically sets the
trigger level to the nearest lower value.
The available Trigger Level range is 100 – 148 dB(L)
