Use the ↑ and ↓ keys to select the type of monitoring you want to use (See the
Monitor Modes section for details about each available option):
SELF TRIGGER (Waveform) – designed for situations where data
collection is needed for a short, precise period of time (normally less than
60 seconds). This operation captures the complete digital waveform for
analysis. Each event is stored individually in internal memory.
BAR GRAPH – designed for situations where large data collection is
needed for long periods of time (normally over 60 seconds and lasting for
hours or days). Seismic and/or air data is collected and recorded in a bar
graph (histogram) format and stored in the internal memory for future
use.
COMBO – designed for situations where both bar graph and waveform
data are needed. The files for these will be split into each type and stored.
